[@AlexAnteMachina]

To be honest, I worked at an hiking/trekking shop and I knew this for years. Since then I became a huge fan of ponchos. Especially expeds‘ pack poncho. Ponchos allow more airflow underneath and do not even try to lie about „breathability“ and protect you AND your gear from becoming wet. Also it is easy to put it on/off during light rain or when the rain pauses for a few minutes: The poncho can be attached to the Backpack so you just throw it over your head and it hangs there behind you and when rain sets in again you just reach back, grab the thing and pull it over your head again. And in case of very heavy rain or wind you can combine a poncho with a pair of rainchaps to protect your legs, but they leave your crotch open which helps ventilation by a higher amount! That said: Great Video! Thank you for that much time and effort! It’s always a pleasure to watch your videos!

[@wimahlers]

Experienced and did the same ... since 1986. Since then I wear a rain jacket in the city and a poncho when backpacking. Also, I still use a backpack with an external frame (heavier, but better airflow and better load bearing when needed). To clarify, I still have 2 Goretex rain jackets. And I also own 3 backpacks with internal frames.

After spending $1000 on a “gore-Tex pro” jacket, I thought it was the best jacket going for years. But after multiple rainy days on trail I noticed I was soaked on the inside.

Arc’Terxy warranted the jacket for me and I bought the same model again.

100%. I've worked professionally in the ski industry as a Lift Operator for years, and we have to spend hours standing in blizzard conditions, rainy conditions, and everything in-between while working hard shoveling snow and doing other physically demanding work. And I can tell you as someone who professionally is paid to be outdoors and do sweaty work: the best waterproof jackets you can get, are just the fully rubberized heavy duty rain gear. And if you want to stay warm, just have a puffer underneath. These crazy goretex systems are just completely unnecessary and most of them get you wet anyway. Just wear an oversized rubberized rain jacket so it allows air to move underneath it and you'll stay much dryer.

I work as a full-time glacier and alpine guide in Iceland and have owned many Goretex layers. I have noticed that a nice new Goretex jacket works well during a chilly alpine ascent (due to both the humidity difference and fresh DWR coating). This is why I only use Goretex for high-alpine trips or ice-cap related activities. When it comes to daily glacier guiding in the rain (a high-humidity environment), Goretex is worthless. What I started doing is just buying cheap rubber jackets/pants that both last longer and are exponentially cheaper. Great video!!

It was during my time working in Iceland that I figured that I didn't like GoreTex because of how wet I would be on rainy days. Bought a 66° fishing poncho and I love nothing more than that

How are they exponentially cheaper? Do they get more and more cheap over time?

[@megalep7025]

Agree, but the problem for me is that rubber clothing is very bad when the sun comes after rain and the only thing you need a jacket for is as a windshield. Under those conditions goretex is far more comfortable than rubber... And if you are outdoors fro some weeks at a time only rubber outer-clothing is not comfortable

As a textile designer of 30 years, I really loved the video. The other part of the story here, other than the membrane and fluorocarbon, is the base fabric design and membrane adhesive formulation and garment construction. In the case of the garments or brands you mention, these are all flat filament CF fibers, likely polyester or nylon 6. Air textured yarns, spun yarns or fiber blends will have an impact. The weave design will have an impact. For example, a plain weave vs a basket weave, or the thread count ... 45 threads per inch vs say 55 of the same yarn count in warp or fill. Microporous films may have a lot of polymer melt adhesive for durability, which may negatively affect breathability, or a little bit of adhesive which give a better feel. There are also breathable coatings, in the microporous option or hydrophilic option. And of course, apart from these factors, there is garment design. A well known brand and high price tag, doesn't necessarily mean the best product. It should also be noted that C8 fluorochemistry is being phased out in favor of C6 for environmental reasons.

[@benh9781]

[@JHMC-s2x]

In NZ, the places we hunt often average 200+ rain days per year, and it looks like the jungle from Jurassic Park (it literally is). We wear wool. It stays warm when wet, and we don't even pretend to attempt to stay dry. Rain jackets are for cutting the wind basically. It's also quiet when you brush again stuff unlike all the synthetics. If its a really really bad storm, an old school fisherman's yellow PVC rain jacket outperforms anything.

[@hoilst265]

Similarly, at the opposite end of the spectrum - in the hot parts of Australia, there's nothing better than...linen. You know all those fancy-schmancy hi-tech sports fabrics that promise to keep you cool, wick moisture, and dry fast? Yeah. Linen does that already. Cold to the touch, hollow fibres. And those synthetics? They really only work when there's a breeze blowing on them. Otherwise, it just feels like wearing a garbage bag.

[@leonsappl]

Yes agreed. I basically only wear wool and outer being with a lanolin coating. For sedentary torrential rain any waterproof cover doesn't need to be breathable. In Australia we have the bluey jacket, the UK has the donkey, the US mackinaw, French I forget the name. NZ has heaps like swandry, feathertop. All basically the same. Dense wool weave with lanolin. Bush shirts more a light flannel weave. Went out of favour with goretex and the like. some trades in Melbourne and tassie still use them. If going without waterproof jacket in heavy rain arguably high wicking 100% synthetic better because absorbs very little water but I still prefer the benefits of wool and adjust my behaviour to compensate

[@leonsappl]

​@@hoilst265Yes true but for hot dry climates the physical attributes are completely different. You want loose fitting clothing that is a loose weave/knit to allow air flow and encourage the body to Thermo regulate with sweat. As for materials yes agreed linen/viscose/lyocell/cotton and even wool. Yes completely agree wearing synthetics in the heat are completely flawed logic. The only synthetic I'd possibly recommend would be polartec delta but have never tried. This tries to mitigate the discomfort of cotton shirts wetting out from sweat by creating mesh grid of synthetic next to viscose. One section stays dry and the other absorbs moisture. The concept being you don't get completely soaked from sweat

“When humidity is high, these jackets don’t seem to breathe at all.” This was my experience with Gore-Tex hiking the West Highland Way in Scotland.

@@danthelambboy Military poncho comes with a liner, so standard layering on self, liner inside poncho, and fold around body to secure with belt or rope. Arms are typically down to side so you don't lose that much body heat, esp if already moving. If it's blowing that bad, you should probably stop to take shelter anyway. There are some trade offs to a jacket, but weight, versatility, effectiveness, COST - it's really hard to beat. If you're going into an area where it could turn nasty enough - just bring a cheap set of Togs to boot. You can strip naked in jugle with poncho on to the other temp extreme of zero +/- with clothes, togs, and poncho/liner to act as wind/rain break - for what - less than $100 and 10 lbs of gear?

I'm a former REI sales specialist in camping and outdoor clothing. I was geared up with all the best equipment and started out on a long Appalachian Trail thru hike and quickly realized that GoreTex and other similar fabrics were indeed useless in the rain soaked conditions on the trail in the humid south. The best thing was to just suck it up and expect to get wet and hope to dry out later on. Open up the vents and pit zips and flush as much air through the jacket as you can. The GoreTex shoes were also useless so again just expect to get wet, live with it and know that you can dry out later on. If you encounter a quick and short shower then you may be protected if the shower doesn't last too long. Often just wearing GoreTex outer wear gets one hot and sweaty and it basically begins raining on the inside.

I own an Outdoor Research Goretex rain jacket and can confirm-- it does a pretty good job keeping you from getting soaked by rain, but it's certainly not dry inside. I always feel clammy underneath especially in the arms. I'm in Iceland (cold maritime climate) and even when I use it as a wind shell, it can feel clammy inside on cold, humid days as well. It works best when you're not exerting yourself (just sitting or walking a bit), or as a wind shell on dryish days, but once you start doing work, it always ends up feeling damp inside if it's at all humid outside.

Thank you soooo much for this video.

[@frstesiste7670]

I'm old enough to remember the pre GoreTex days - at least pre GoreTex where I lived. What I had before where cotton and polyester-cotton blends (like the G1000 used by Fjellraven) treated for waterproofness. These kind of worked - actually really well in misty conditions or with snow well below freezing - but just didn't work well in heavy prolonged rain. I remember biking to school a couple of times in a cotton "waterproof" outdoorsy and almost new jacket and it worked for the 15-20 minutes ride, but after an hour in steady rain it just wet thru. So going hiking with these types of clothes I'd bring a lightweight really waterproof jacket in addition. The other option was to leave the cotton jacket at home and bring only a more heavy-duty rain jacket that certainly would keep the rain out but was unnecessary uncomfortable if the rain let up. Then GoreTex came along, and I bought one of the first jackets available where I lived. And it worked! Not like some miracle fabric that solved every problem, but it was lighter than my cotton jacket and much lighter than an outdoorsy jacket plus a rain jacket. It also kept me at least as dry in rain but was less comfortable than poly-cotton and cotton in warm weather when it didn't rain (no test equipment, but lots of experience and curiosity). I even did a (fairly unscientific but what I could manage) test cross country skiing in around -15C. Same loop of 5 miles three times with polyester-cotton blend, cotton and GoreTex and to my surprise there where clearly less condensation on the inside of the GoreTex jacket. I don't disagree with your findings at all - it's fairly basic knowledge that with close to 100% humidity outside a fabric wont "breathe" much (good illustration with the parking lot BTW, hadn't seen that before). The question is however, what did GoreTex replace and what are the options now? Other waterproof-breathable materials struggle with exactly the same limitations when it comes to high humidity outside the jacket. I've tried Entrant, Triple Point, many versions of GoreTex, eVent, Dermizax and a couple of other with unspecified waterproof breathable technologies and in heavy rain they always struggle and I'll get condensation. But they also replace two other jackets that weigh more and I have to switch between when it's not steady all da rain. I live in an area with fairly unstable weather but even here it's much more common with a mix of showers, light rain/mist, sunny, windy etc. than all day heavy rain and waterproof-breathable tech keep me fairly comfortable in all the conditions. I haven't found anything that works better, maybe except for an umbrella but umbrellas have some serious problems with wind and overgrown trails.

When a daily downpour broke in a Central American jungle, we broke out our Gortex the guide broke out an umbrella.

@@fiatlux4058 if that cold air with little capacity for water is warmed by the body heat it still holds as little water as when it was cold, but has the capacity of warm air.

It is kind of the same principle a hair dryer uses, the warm air can hold more water then wehen it was cold, ort in that case room temperature, the warmth of the air alos helps to evaporate the water too of course. Also it isnt about zero degrees, the ability to hold water drops with temperature in general.

Like many outdoor enthusiasts I jumped in Goretex as soon as it became available in the 1970s, and upgraded through each new generation. It never worked as advertised as soon as the DWR deteriorated or in high humidity conditions. Finally I realized the flaw in the technology. ..just the problems that you identified. The only thing I have found that really works…to the extent that anything can. GOOD JOB exposing the scam!

[@tom24057]

Edit; firstly I’m a fan of the channel. Secondly, GoreTex can be both breathable and waterproof simultaneously, assuming ‘correct’ conditions for the fabric to work efficiently . Gortex works, but it has its limitations. Your test created a humidity equilibrium either side of the fabric; of course this leads to no further evaporation. As you say, in cold/low relative/absolute humidity environments goretex will perform just fine. Raining isn’t a guarantee of high humidity as liquid water and water vapour are two different things, and the DWR is there to mitigate surface liquid from wetting out the fabric. If rain persists, humidity will rise due to the liquid rain beginning to evaporate; raising absolute and relative humidity. However rain is not an indication of inherent high humidity to the point that makes GoreTex immediately ineffective. In cold mountain environments with high winds, driving snow and low absolute humidity (absolute and relative humidity are two different metrics. Ref psychrometric chart for further info) with the user exerting a moderate effort (likely the largest use case scenario for GoreTex) it’ll work just fine.

[@biomorphic]

I totally second this opinion, which I shared in a similar comment. For alpinists Gore-Tex works well. I add that in a rain forrest you'll get soaked with ANY shell, no matter what is the material, so better not to use a rain jacket at all if you plan a trip in Borneo.

The moment I got to the top of the mountain, the air was strong and still raining, closed the jacket completely, the humidity inside evaporated while I set up my tent, and I was feeling fine except for my fingers that froze. Would a plastic bag or umbrella allowed that? Definitely not. What about a cheap jacket? I don't think my sweat would had evaporated so easily. What about a really expensive one? Probably not needed as well. The same goes for the rest of the equipment, that is the reason we don trek in jeans and cotton shirts. We need to be breathable.

I'll admit, I paid over $300 for a Goretex jacket years ago, but never realized I was scammed. I thought it was simply "worn out" when it left me just as wet inside as the exterior rain outside.

[@kai-uweoch1159]

The beauty with all those membrane jackets is that they kind of work under different circumstances. A membrane jacket will protect you from the wind, it might give you a little bit more insulation when it's cold and it will keep the rain off if it's raining. So it's a multi purpose piece of equipment. However you need to know its limitations. This is transporting sweat caused by intense physical activity when it's wet outside - and worse wet and warm.

And correct me if I'm wrong, but nobody has ever said that membranes will keep you dry in 100% humidity. There is no scam - membranes are breathable in conditions when you can use other breathable fabrics and waterproof when you need waterproof

@@dmitriitsunenko9055yeah this video is hilarious because it starts with a straw man argument. Nobody expects it to do both at the same time. The point is that it’s waterproof when it’s raining, and breathable when it’s not. It would be quite a jacket if it could enable you to evaporate sweat in 100% humidity!

[@nauticalwaters]

Love this video and actually it explains how I’ve felt with my goretex jacket through my years of use. 1. Performance in heavy rain - meh, keeps water out. But yes with sweating or anything condensation sits in the jacket 2. Performance for high winds, alpine conditions surrounded by snow where you want to have breathable but shell like barrier to make sure any melting ice or snow is not getting you wet. I’ve been glad to have it The experience above makes sense now with the video

[@RC-qf3mp]

Good video and analysis, BUT… 1) the big pit zips in my Montbell and Patagonia are great, and i regularly air out by fully unzipping and lifting up the jacket. It creates a fast cooling effect which is also reduces sweat. 2) when it gets hot, or i know it will be even just warm and rainy, i use a very thin alpaca or merino layer underneath and then the rain jacket. The jacket provides warmth, and can get muggy, so i do the regular airing out. 3) a big source of heat, sweat and lack of ventilation (air) is on the back, so i use a Vaucluse air ventilator with my frameless, hip-beltless pack. This extra air on the back helps with outside and inside moisture - less sopping wet back sticking to the pack, and less heat from the pack up against the back, which also means less sweat b/c less heat. You always seem loaded out with a huge pack, huge hip belt, and complete contact all over your body. I even stopped using a fanny pack and love the sense of freedom and air all around me. Improved visibility too when i look around on the ground. All this extra body exposure to air and fewer materials contacting me allow for extra ventilation, easy to open/close zip my jacket, i can undo the chest straps for a few minutes of super-ventilation as well. One thing to consider is the pros/cons of a goretex hiking PONCHO. Of course, it would have to have straps for wind, but the whole idea of the ancient poncho technology is that it allows for flexibility in ventilation. As for the click-baity title of the video - perhaps phrase the title as a question. “Is Gore-Tex a scam?” And provide your facts, and let viewer decide. It’s a serious accusation to accuse anybody of perpetrating a scam. I know you just want clicks, but you can get the clicks without the formal accusation. If a specific manufacturer makes a specific claim that you think is, at best, dubious, then let’s see that specific statement and why you think it’s dubious or false. But no point in risking yourself from defamation to even go there, and you don’t have to. You provided a solid analysis that speaks for itself.

In my opinion it’s somewhat not a scam. If it’s dry outside you have a nice breathable jacket. If it than starts to rain, you don’t need to switch to a raincoat. It’s like 2 separate jackets in one. Just don’t expect it to be both at the same time

I worked in the extreme sportswear industry and we knew that the best that "breathable" fabrics could do under the ideal circumstances was about a 7% improvement. If the outside or inside got wet from precipitation or sweat, it was like a thick plastic sheet. But if you did not have "breathable", few people would buy. They were well trained consumers. Since we had an extreme customer base who knew when things were working and not, we were very early with the zip vents in pits, pockets, pant legs, .... And we had the flap vents also.

[@lfcbpro]

I wouldn't say 'trained', more like lied to. The absolute BS by any brand with Gore-Tex, even still today, is amazing. You'd think it was the best thing on the planet. But most people who have used it know it simply doesn't work as intended, and the best you will get is a very waterproof item for a few years. You'll still get soaked inside.

[@Alche_mist]

One thing with the PTFE toxicity: Short perfluorinated chains are troublesome, but the truly long ones (i.e. PTFE coatings on cooking or chemical gear) are so stable (including thermostability), that as long as they don't come into contact with reactive or sharp metal, they are very safe. And while the membranes are generally made with the "safe enough" molecules, the overcoating is decidedly not.

[@FatherTimex]

I think maybe you are ignoring the fact that a breathable, waterproof coat is still useful, even if it can't do both at the same time. It lets you have a jacket that keeps you dry in the rain, even if your sweat still gets trapped, which is better than just getting soaked by the rain, while also having a breathable jacket when it isn't raining.

[@TacShooter]

All I can tell you is that the Goretex ECWCS Parka I wore in Alaska in the Army in the late 80's was thin, lightweight, and utilitarian and kept me super warm and dry. It was a huge improvement over the fluffy layers of the old parka we were issued. If that Goretex was a scam, sign me up for the scam. I rarely needed to wear the fleece layer underneath and usually wore only my usual summer Army uniform underneath.

[@cardgenius1]

Gore-Tex in a jacket works great here in Colorado. It's very dry and when it rains, it doesn't do it for long so it keeps the water out very well. Sometimes you'll get caught in a nasty storm and your jacket will get soaked through but the storm will be over in 30 minutes and then your jacket will be dry 10-20 minutes later. Boots on the other hand is a no go for Gore-Tex. The membrane just can't keep up with the amount of sweat you produce which results in soggy wet feet. Boots with good ventilation and no membrane will stay much dryer, even with the many stream crossings we have to deal with in the High Country.

I’m out in the rain the snow the ice as a part of my job and sometimes for long hours. I have pulled 72 hours straight no sleep . The best rain gear I have found is a combination of a good old-fashioned army poncho with a set of rain gators (to keep everything from your knees down to your waterproof boots dry) . All you have to do is every so often when the heat and humidity buildup underneath, the poncho is just flap it to vent it. Gortex and other high-tech fabrics suck in those environments and believe me I’ve tried everything. Lots of guys love Carhartt in the winter. yet if you work beyond 12 hours the humidity from your body wipes out the insulation value and you get cold. This is where polypropylene or wool as a base layer ( I like prefer wool for safety reasons it won’t melt your skin if something goes horribly wrong) fabrics a wool insulation layer and gortex really shine particularly in high cold wind and snow .

[@pinetree5489]

Just going to share an experience that may be helpful to others. Hiking some years ago in N.H. in November. Some snow on the ground, snow in trees-melting and dripping, exceptionally wet. Temps 33-34F. After maybe 3 hours, we arrive at the shelter soaked to the bone and while fine hiking, begin to chill quickly once stopped (as expected). Instead of changing into some dryer clothing, realizing that the wet clothes won't dry well at all, I decided to just walk (w/o pack) at a speed that generated heat but not enough to sweat while opening my jacket zipper and vents accordingly. After about 20 minutes from the shelter I felt the idea was working and turned around to head back. Back at the shelter after about a forty minute leisurely walk, I was bone dry! We were higher now in elevation so trees were much shorter (less dripping) than 'in the forest.' Even the outer wear was dry (breezier up high). Probably (as I remember it), only my leather hiking boots were still somewhat wet. It was great learning experience in managing wet conditions.

The more you are moving, the more you sweat, but also the more you are forcing fresh air through the vents. Another huge difference was switching to a mesh ventilated backpack.

Really appreciate this kind of content! Really good companion to the FortNine video that did something similar for motorcycle jackets.

I just couldn't justify spending multiple hundreds of dollars on a jacket that with exposed membrane (like the Gore R7 Shakedry) that I would almost certainly need to replace in a few years of heavy use because it literally would just not last that long. The exposed membrane literally wears down with things like a running pack on for example.

Another point that i, for some reason, rarely hear in the WPB fabric debate is that sweat isn’t just water. It has a fairly high concentration of minerals, which also make it harder for the water to evaporate. And when after extensive use these minerals pile up on the inside of the goretex membrane, they can actually pull the water in through the goretex. Which is especially a problem with goretex shoes.

So this is a surprise to anyone? I've used them since the 70s, and they never worked perfect, but they were noticeably better than the hard-coated urethane jackets we used before. When you're backpacking, you only want one wind/rain shell. Sitting around in a rubber jacket to keep the wind off sucked, so the so-called waterproof breathable jackets were way better for that application. A few of my friends had expensive ventile parkas which might have been the best compromise, but like today, they were very expensive.

Small correction: The membrane is the same ePTFE that Gore-Tex has always used. What has changed is that DWR coating on the outer layer of the jacket. Gore-Tex jacket makers used to use C8 florocarbons as the DWR, then switched to C6 when C8 was banned, and now some jacket makers will use other DWR. The point is, the membrane is fine, the problem was and is the DWR treatment on the outer fabric.

I've known this for years! The capacity of Goretex to transpire moisture depends on a differential in vapour pressure. When it is raining it is 100% humidity outside, and when it is 100% humidity outside there is no vapour pressure differential to drive your sweat out through the membrane. So you get just as sweaty as as you would with much cheaper impermeable waterproofs. Goretex is at its best in cold dry conditions. My solution: a silnylon poncho. It's airy, much lighter, and you sweat a lot less. And a hiking umbrella.

[@TheRedStarman]

I'm a delivery driver for Amazon. When it rains, I stay driest when I have the heater and air conditioning running. It really is all about how much capacity the air has for water, and if it's being dehydrated (due the AC), my clothing dries far more quickly than if I just turned on the heater itself. Delivering through several back to back storms in a month taught me that.

[@MonoBrawI]

Note that even at 100% humidity your clothes will continue to dry out on you when the air around you is colder than your skin as the boundary layer warms up and can absorb more water. In practice I find 100% humidity fine at 20ish degrees C as those translate to roughly 50% at ~33C temperature of your skin.

[@robertcarpenter7890]

If you look through the different membranes they make you'll find that they already have this fabric dialled, it's called gore shakedry and has been implemented in mainly road biking and trail running attire. Due to it essentially being a reversed 2L membrane it shed water off immediately and had a waxy finish, it worked exceptionally well in rainy conditions but due to the fragility of the outer fabric it meant that the membrane would break down under heavy loads. It was designed for little to no need for packs (road cycling, running and trail running) and I can say that with a heavy pack my jacket lasted under a year before there were major leaks in the shoulder and hip areas of the jacket, this too applies to any waterproof and breathable jackets with super light membrane qualities as they're mainly designed to be used sparingly and infrequently in hot climates or in extremely high output pursuits where large packs are not involved

Hi Steven, great video. I've found that Goretex works excellently as a ski jacket outer shell. I think skiing is an ideal environment for it. It's dry and cold outside and you're only producing a small amount of vapour inside. Plus, the airflow is quite high as you're moving fast. I tend to buy used Goretex items and reproof them. The older items were built to a much higher standard and I prefer the style of original Latok or Berghaus. They were very well designed. One of my biggest bugbears is laminated pockets etc which detach too easily. Also, my one key feature for an outdoor jacket that tells me it's been designed by someone who knows: Pocket zips must close downwards!

About 30 years ago, I bought a hooded rain jacked, and rain pants. Both were Goretex garments. They were water proof for a few years. Then, they were magnetic to water.

[@drumbrakes]

Thanks for a good video. 2 comments from me: 1) your test setup might benefit from a wick in the water to help it evaporate - perhaps an offcut from a wicking baselayer product? 2) I absolutely agree that goretex and all the competitors don't wick well during rain, but when the rain is frequently on/off all day long (Or all month long in Scotland), then you get the benefit between rain showers. It's still cold and it's still windy, so I'm not taking my wet jacket off to pack it in my bag. I just keep walking/riding and if it's a good breathable fabric I will dry off pretty inside the jacket quite quickly. Even when the outer layer has wetted out, a 30 mph wind will dry that pretty quickly, and a good tight fitting wicking base and breathable intermediate layers really help get the moisture inside to evaporate. I've also spent a summer riding in the southern half of the US. The weather is much more humid, much warmer, and more importantly, it usually rains very heavily for 30 minutes, and then the sun comes out again for the rest of the day. In those conditions, it's easier to just get wet and then dry again, or put on a waterproof when the rain starts and take it off when the rain stops.

[@jacksmack2382]

What you miss in this video is that, as long as the temperature inside the jacket is higher/warmer than outside the jacket, there is still a vapor pressure differential that should drive vapor from inside the jacket to outside the jacket, even when the outside is wetted out. The problem is that this differential is generally not sufficient to transfer the amount of sweat generated while hiking.

[@jimwing.2178]

That's a myth. If the outer air temperature is below dewpoint, then the vapor will condense before it makes it through the Goretex. Since liquid water can't pass through, the membrane will wet-out and block the passage of vapor.

[@johndavies1475]

[@At-07461]

Pit zips do work in such conditions. If it's not enough, you have to unzip/open other areas. Perhaps just not enough at times. Once when I was younger,, I was slogging up to Muir pass in the High Sierra wearing a T-shirt and poncho in light rain/sleet and was pouring sweat while doing so. It was fairly chilly. Still a ways from the pass, I started shivering for a while which then eventually stopped and I felt dead cold inside. At that point, I knew that Hypothermia was approaching. I can't describe it other than to say that I felt cold "inside" and knew that if I didn't do something IMMEDIATELY that something bad was going to happen... I quickly set up a windbreak and fired up my stove to make some hot soup and staved off the big 'H' at that point I think. Could have ended up much worse. I later used the first version of the US military Gore-Tex jacket which had pit-zips and a liner (which I still have) and it worked well enough but was heavy, durable and warm. I eventually switched to the first version of the Marmot Streamline Gore-Tex jacket which was incredibly light, had a mesh liner with pit-zips and worked great. Then they switched to no liner and it worked less great. It seems as if we're regressing at times. Haven't been hiking for quite a while but from the looks of the comments, little has changed...YMMV. 😉

The best thing ever to keep you dry is a plain good old poncho, open at the bottom to vent out, waterproof at the top and hood to protect you, but even a poncho has limited use; You can only walk, no climbing or working in it...

[@WhiteBreadThunder-op6in]

Kudos. The time and energy you put into research and production of this short video is incredible. Best rain jacket explanation ever.

[@alynnhiscox7303]

I've been an all-weather hiker and motorcyclist for 40 years, and only bought a Gore-Tex labeled product once. It worked no more efficiently than my standard rain gear, cost me a fortune, and was an overall disappointment. Thanks for doing such an in-depth study on the non-effects of Gore's waterproof/breathable claims. You're doing a great public service by showing that one does not need to spend huge amounts of money on gear to achieve good results. Of course, that leaves more money for other new gear! :) Great channel!!

Bilt rain jacket is hard to beet for the price.

Bilt is a crapshoot. I've had some gear fail immediately and some last for years 🤷🏻‍♂️

@@rrandydduke I've been riding with Olympia gear for several years, and their rain liners work extremely well. I carry the lightweight liner to use when hiking as well.

I think in dry conditions, in the mountains, where wind is very common, Gore-Tex works. Otherwise no athlete would use it. It is not a bias, it just works. Also it does for daily use. I have an Arc'teryx shell, and it keeps me dry when it rains in the city. Yes, you may need to reapply the DWR once in a while, but it is not a big deal. It is a spray. I don't use the shell often, because for light rain DWR is enough, you do not need Gore-Tex at all, so in 5 years I never had to reapply the DWR yet to my shell. I used the shell under heavy rain and snow, and it kept me warm and dry. That was in winter with multiple layers below, up to -10ºC. In a rain forrest, there is nothing you can do. The humidity is so high that it is pointless using a rain jacket. It is ok to be soaked when there are 30ºC. But if you get soaked at -20ºC you die. So, it may not be the best product on the market anymore, but Gore-Tex is not a scam, not for winter shell jackets, at least.

It’s a big deal that you’re poisoning the planet with your respraying of PFAS coatings

[@canoedude]

Where I find that goretex works is in cold weather paddling gear. You need the waterproof-ness when in the water. You're going to sweat while paddling. The breathing happens when you get out of the water - I'm frequently wet inside the garment while paddling (sweat) but am dry but the time in have my boat loaded. I have adopted ponchos for when I'm hiking - very well ventilated. I use a belt sometimes to keep them from flapping.

[@Brurgh]

Regardless of whether you want to buy or own a goretex jacket, the information regarding how to remain dry is valuable. You need airflow between you and the waterproof layer, to prevent water saturated air lamination. This then prevents you getting wet from your sweat. So a fully waterproof layer with ventilation is best in any condition. Goretex seems to be good when it's super dry outside. But if it's wet it's not as good, but still usable if it has ventilation. But is goretex worth it considering the environmental impact, likely not.

[@robertos4172]

I think it even worse that stated: If you have Gortex boots even on a low humidity warm day, the rate you create moisture overwhelms the silly slow rate the gortex can breath. You might as well be wearing plastic bags on your feet if you want to ford a stream. It is completely worthless.

[@austinrhubarb]

Yeap. I've had 2 pairs of GoreTex hiking boots from expensive brands, and have been disappointed with both of them.

[@reccecs4]

There’s different grades of goretex for footwear. The insulated / performance / extended grades in the Comfort range for footwear are designed for different temp ranges. Even some military desert boots use Extended Comfort, mainly for pathogen protection ie from dirty Afghan open sewers. It works great in hot weather. I’ve worn boots with it in the summer with it no issue, breathes as well as a non goretex boot. Absolutely critical to use the right products with it though, regular polish will make any boot a sauna. The real hassle is drying them in the field if they get wet inside; basically forget about it until you get somewhere dry. If you know your boots will get wet inside you’re better off with a non WP boot and using WP socks instead.

[@SolarCookingGermany]

Right, I had Gore Tex boots about 30 years ago. Never again!

[@trentvlak]

The only good thing about goretex footwear is that the waterproof membrane is inside the boot so the outside can get damaged but your feet still won't get wet when going through puddles.

[@2pintsofcremedementh]

Wool for warmth, oilskin to keep you dry. There's a reason that's what farmers wear.

[@philipgriffiths9859]

True. Never seen trawler men wearing Goretex either.

[@RobertParker-v7v]

Pretty much exactly what I came to say. Except for times when I need to keep weight way down, I'd rather go with an oilskin jacket. I'm just as sweaty with it as with Goretex, but I'm drier in the rain.

[@ebec2believe776]

Just found your video and THANK YOU!!. Recently far from home on a trail and the discussion of rain gear came up. We are from South Florida in the Rainshine State. There is no rain gear technology that breathes in South Floridian rain. Either get wet from the rain or get soaked from the abundance of sweat from being wrapped in plastic. Quick rain, quick dash from dry to dry then a rain protection makes sense. More than 30minutes its a wash. Nothing can breath during rain event or Miami humidity, its basically one in the same.

[@ebec2believe776]

I will admit a nice design w/GorTex makes a fantastic wind breaker for freezing cold morning in SoFl when the temp dip into the 50s, brrrrr

[@kenoskyiscool]

Rain jackets, in particular for hiking, are meant to keep you warm, not necessarily dry, to help prevent hypothermia.

[@NordicOutland-amazon]

I think it is most important to keep you dry i/o warm. A mid layer or vest should do the job for warm.

[@durstongear]

Great video. Big effort and well explained.

[@medic2299]

Absolutely right. Been saying this for year, which is why I went to a poncho years ago. The only time I'll use a breathable jacket is like you mentioned in the video, winter / cold weather............... The poncho otherwise is a great option because air is constantly moving in and under and all around. You will notice if it's raining, you WILL get wet. There's really no way to avoid it......................

[@jondspen]

Well - unless you're doing REALLY cold (like mountains or near artic - or job where you need full protection) - poncho still best IMHO. Layer as you want underneath, put on poncho. If you want to trap air, fold it around and put a belt on outside. Plus if sun come out, you don't have to stop to take off, just throw back over your shoulders.

[@majksenkerik7397]

@user-hj8iq1zr8g because the cotton will sooner or later start absorbing the snow as it melts on you and will get wet. Which is a bad thing especially if you are, say, crawling/sitting/kneeling in the snow. GT gives you a hard shell with some breathability that actually does work in cold.

[@Detvanliga]

Well, it is not always raining, is it? Sometimes it is cold and then I sweat. And if I wear Gore-Tex that sweat is actually ventilated out, while the jacket is keeping me warm. .

[@emu314159]

Literally any buffer layer will keep you warmer then. And dry.

[@imagesolu]

love it I worked in the garment industry for 15 years, doing design and fabric testing, i have been telling people for years to stop with this non-sens waterproof breathability scam... there is no such things as breathable to start with, a fabric does not breathe it let moisture out or absorb it more or less depending on the construction and the fiber used.

[@topendgold9284]

I live in a tropical area. When it rains, nothing except shelter will keep you dry, the best clothing to wear in the rainy season, is quick dry clothing. If it's hot , but still in the wet season, you are going to be wet with sweat anyway , again, quick dry clothing is the answer. I do a fair bit of prospecting, and carry a camel back water bladder and small storage pouches, I carry a small telescopic umbrella, which is very handy, provides shade when needed as well.

[@SpaceCaptnFace]

In the army, people made gortex and gortex covers to be the be all end all best piece of gear. My first time downrange on fort Carson and it stormed like crazy.... Commander was like "make sure you've got your gortex cover on your sleeping bag". Sure thing buddy... As an hour later the whole unit woke up soaked in their bags

Gave up on goretex boots years ago. Oh and pit zips are the bomb!

[@kiwibloke2000]

Yeh, but breathable jackets are essential, live saving when you are in alpine conditions where the air is dry but cold enough to freeze your sweat...if it doesn't evaporate...and where pit zips don't keep the wind out. For wet hiking I have gone towards a rash shirt and softshell vest. Don't try to stay dry, just warm.

[@undrellx]

That and the PFAS cancer chemicals they're made of aren't compatible with excretion, so literally the only way to reduce the amount of them in your blood stream is to give birth to a baby, who in turn takes away some bio mass including some of the PFAS. Possibly the worst gift you could give a new life.

[@peterberry8494]

I wear a goretex jacket and pants for resort skiing. They have been 100% waterproof even during all day wet snow, with falling, sitting on the snow etc, until the seams go or they delaminate. For resort skiing, in a gondola/bubble or a mountain restaurant, you can see the steam coming out through the jacket, and you don't have to keep farting around with the front zip, pit zips or taking the jacket off. Similarly if it stops snowing, the moisture underneath comes out. So waterproof AND breathable is useful if it sometimes stops raining or snowing on you. I get that this is a hiking channel, but think it's worth a mention that the situation is different for skiing. ps all that stuff about needing a humidity gradient between inside and outside applies also if you're wearing just a pair of shorts or a wicking baselayer. Sweat will not evaporate when the humidity is high.

He said it basically didn't work. He wasn't recommending one over the other, was saying they changed it to say it's better but it isn't. None of the Goretex (original or copies) work without airflow and with humidity. In the end he directs to another video where he covers a range of rain gear. That was the point.... All of these types of jackets are a scam. the science shows that they don't work.

[@daveshilling2673]

He clearly explained that the green jacket is functionally no better than the orange one, because there's no airflow regardless, and the air is not dry enough anyways.

[@christopherpardell4418]

I used to have a North Face goretex jacket that I loved. But because I paid attention in high school physics I never expected it to ‘breathe’. If it’s humid enough to rain it’s too humid for perspiration to evaporate. It’s why Biloxi is sweaty hell in the summer even with your shirt off. What I liked about it was it was windproof, and waterproof, so I did not get drenched in rain, nor chilled in a breeze, and it could be stuffed into its own pocket to fit inside a pack.

[@SchumacherAcosta]

I appreciate the amount of thought and time you take to test - keep up the great work

[@jewelhome1]

Thank you. Some real science. There is also a temperature gradient from skin through any insulation to the inner jacket surface. As moist air moves through the insulation to the surface, it cools and loses capacity to hold water vapour. So the water condenses out into droplets which cannot pass through the GoreTex and soaks the interior. I’m always wet wearing the stuff.

[@austingavins9181]

Here in Ireland it is constantly high humidity for most of the year, with temps usually ranging from -3 to -4 C to 20 to 25 C. I am yet to find a definitive "waterproof" that will keep rain out and allow moisture to escape. However, I am finding some success using a Poncho during summer (sil nylon and plenty of "breathing" holes!) and am trying a Paramo jacket during cooler months. The Paramo is interesting as it doesn't use a membrane and relies on a "pump liner" to force water/vapour from the inside to the outside using your body heat. It also adds a Nikwax (water based) DWR to the outer fabric. Only used for a few weeks so far, but it appears promising for the way I hike and how "hot" I run when hiking.

[@craiglang3492]

I’ve just about worn out my Paramo jacket from 5 years of year round use summer and winter in Scotland. Best jacket I’ve ever had. Walking, cycling, hiking. Warm in winter, not too hot in summer. Would definitely buy another one. And it doesn’t make rustling noises like a standard waterproof jacket.

I think the idea with a breathable rain jacket is that you don't have to change when it starts raining. Obviously you do not want to wear a non-breathable jacket when it is not raining. Also, once it stops raining, you will dry up. I wear breathable waders when I go fishing, and it makes a huge difference since at least dry when I'm off the water for a while.
