I own or have tested the Exped Downmat UL, Nemo Tensor Alpine and Tensor Insulated, Sea to Summit Etherlight XT, and Thermarest XTherm (all in long-wide) so I can give you points of comparison with the pads in this review. Of the pads he tested that I own, I concur with all of his findings. Measured pad specs in LW (77"x25"): Downmat UL 11.5"x5.5", 34.1oz, R-7.2; XTherm 10x4.5", 27.7oz, R-6.9; Tensor Alpine 9.5"x3.5", 26.2oz, R-4.8; Etherlight XT 10"x5" (12"L with the pump sack at the end), 25.5 oz, R-3.2. The Etherlight is by far the most comfortable (especially for side sleepers), Tensor is second (the Alpine feels the same), Downmat UL is third, and XTherm fourth (though still relatively comfortable even at only 2.5" thick). As a side-sleeper I have to air-down the pads enough to conform but still keep me off the ground. They all loose considerable R-value when you do this, except for (amazingly) the XTHERM. The Downmat UL has a higher R-value of 7.2, but performs second in this regard because it only uses down for insulation, and is equivalent to having an uncompressed down bag underneath you, so it's R-value will be relative to it's thickness. The Tensor and Tensor Alpine live up to their R-value only when fully inflated, but get very noticeable and uncomfortable cold spots under the hips and shoulder when you air-down (as the spots without foil get closer to the ground and transfer more heat). I still feel these cold spots even with a Nemo Switchback R-2 closed cell foam pad underneath in anything below 30-35 degrees. I can comfortably use the Etherlight and Tensor down to these temps if I put the foam pad ON TOP of the air pad (don't ask me the thermodynamics of this, but it's a tried and true method). Below 30 deg I use the Downmat or XTherm, and anything below 15 deg I use them in combination with a foam pad (mainly to keep from dying if the air pad pops). Tensor and Alpine are both very quiet and are the most compact of these pads but the material is very thin. Love these pads for cool to warm weather but I've had two go flat on me, either from pinhole leaks or air leaking out of the valve. The valves can be somewhat annoying. It's second only to the Etherlight in speed and ease of inflation, but the valves can be hard to open and close, and sometimes the 'deflate' valve pops out when your'e trying to open the 'inflate/adjust' valve (they are nested) and dumps the whole pad, and the 'inflate/adjust' valve sometimes doesn't seal (leaks). The Longbow Alpine version may prove to be more robust though 9 oz heavier. Etherlight is the fastest and easiest to inflate and adjust. It's well made and uses thick enough materials not to be too concerned about punctures. Though not as quiet, compact, and light as the Tensor, for me the trade-off for comfort and reliability is worth it. This is my favorite pad by far for luxurious mild-weather backpacking. XTherm is my go-to pad for cold weather despite not being the most comfortable or quiet--simply because I have the most confidence in the warmth, materials, and valve (they are the most robust), it has the best weight to R-value ratio, and it's still more comfortable than 80% of the other backpacking pads out there. Yes, it's by far the loudest, but I don't really notice when I use it in cold temps because I'm in a thick bag wearing a beanie and I can't hear anything anyway. Your tent-mate however may be annoyed. Downmat UL would be my #1 cold weather choice if I were a quilt user. It has the most comfortable materials (almost fuzzy), is quick and easy to inflate and adjust, and though vertical baffles are not my favorite, is quite comfortable. Plus the raised side baffles help keep you on the pad. Downsides--it's the bulkiest, heaviest and has some users reviews reporting it popping in their tent and spraying feathers everywhere (I haven't experienced this myself--fingers crossed).

First off, I like your scientific approach to this topic. It's very interesting. But, there's something you need to understand about how IR Cameras operate. They measure the thermal radiation being emitted from an object, but depends highly on the emissivity of the object (or the effectiveness of the object to emit radiation). Surfaces vary in emissivity from 1.0 (perfect blackbody) to 0.1 (shiny copper). The different surfaces of the sleeping pads may have been throwing off the temperatures being measured by the camera. A better test would have been to place a lightweight strip of fabric or even electrical tape (e~1.0; this is what thermographers use) across the surface of the pad and measure the temperature there. I also agree with the others that a common range or color template would have been a good idea, for comparison purposes. I'm looking forward to the next video. Thanks.

Also what can be added - contact has huge impact on thermal conductivity. Mats are going to conduct different, while are loaded. Some kind of additiona mass could be introduecd to compare results whith some preload. Also IR camera stuff above is important as hell. Values may vary a lot. BUT I like very much the approach. good way :).

@EliasLabordus3 жыл бұрын
Thanks. Couple remarks: First, the scaling is different for all pads on the temp map. So it gives a skewed image (When it looks more blue, it gives the impression that it's better, but that is not necessarily true). Second, I think the heat reflection is meant to bounce it back up, not down. So you should probably have put the pads upside down on the heater.
@SleeveZipper3 жыл бұрын
Nice testing method. Thanks! However... :-) The idea behind the Static V design is such that the v-shaped grooves are filled with the sleeping bag material when you lay on them. So that’s how they turn out a bit warmer than you would expect based on your test. It’s probably not an enormous difference but from experience I can say the mat is not far off from my insulated Exped down mat.

Good test. I tend to just bring a closed cell pad, put my regular pad on top and now I magically have an "insulated" pad. You don't have to go bankrupt buying dedicated winter gear to go backpacking in colder weather. Bring an extra blanket, double up your sleeping pads, wear a hat and some warm heavy socks to bed. And carry a few hand warmers to fire off inside your bag if your particular version of the McGyver "winter" bag isn't cutting it at 2AM.

That said, I don't know if I'd thru hike with it over the insulated Klymit. There have been reports about being less durable.

This was very throurough, so cool. I have a suggestion for a thing to try, which could put many an online debate to rest. I don't have a thermal camera or otherwise I'd do it myself. People are always arguing about how much space blankets/mylar/reflectix does or does not add. I think it could be really cool if you could film your pads with a sheet of that. I'd propose this stack: Control: 3D printer bed cloth to spread heat Sleeping pad (face down) black cover blanket (to get uniform temp readings) Test: 3D printer bed cloth to spread heat Sleeping pad (face down) Reflectix/mylar (shiney side down) black cover blanket (to get uniform temp readings) The argument is usually that the reflective foil can't work because the pad is touching it, while others insist that it adds meaningful warmth to their system nonetheless.

This is the best video on KZbin for sleeping pad evaluation. Thanks so much! I have a Nemo Tensor wide pad. It's rated at R4.2. It's confortable, packs relatively small and is reasonably light. Also have a Big Agnes AXL mummy. It's only 20" at the widest point. My arms kept falling off and getting cold so I bought the Tensor in 25" width. My summer go-to pad is a knockoff of the Klymit V. It has a claimed R value of 2.2. Only 16 ounces and pretty comfortable for back sleeping. Price difference was about $100, and the quality difference is obvious. That said, I'm trying to lighten my load so when the weather/temps allow I go with the lighter pad. A tip; I use a silver mylar coated bubble wrap pad under my pad to increase R value. It's recycled packing material from Hello Fresh shipping container. (They no longer use it.) 2 ounces for a 22 x 60 inch piece.

Great content! Love that you went through all heat loss mechanisms. How you use a pad makes a big difference as well, especially on snow. I camp in floorless tents in the winter. I dig a pocket for my inflatable in the snow (tensor insulated mummy) then overlay a 1cm smooth evazote pad on top (failsafe winter contingency, and improved comfort, really, bed-like). Total r-value 4.9 for the system. Snow often has a high air content, even as it compacts you don't need crazy high r-values to be comfy. I've been a couple times at -20 to -30 and was totally fine. Biggest issue at those temps is breathing comfort. Layering is a great concept for sleep systems as well, pads and bags. I do everything with a combination of a 0 degree bag, a 32 degree quilt and the two pads above.

15:30 You have to make an integral of every spot/temperature across the whole surface above the heated bed, in order to compare... And not compatre only the highest temperatures with each other. For example: The 3rd (upper line, right) has a lower hot-spot-temp than the 4 (lower line, left), but still, the hot-spots on the 4th are miniscule compared to the hot-spots of the 3rd (if the temp-scale was chosen to be always the same, which here isn´t the case, in as much as I can judge it: 3rd: 55 to 65,9°. 4th: 60,6 to 67,6°C), so the 4th is surely better than the 3rd, simply by eye. If the results weren´t so clear as in this case, then, judgment by eye/vision wouldn´t be enough, and in that case, you´d have to make an integral over the whole surface corresponding the surface of the heated bed.

@gregsantos93923 жыл бұрын
One thing to keep in mind regarding this test is that it doesn't take into account the insulating properties of the sleeping bag on top of the pad. Sleeping bags insulate best when the insulation if fully lofted. When the insulation is compressed (by your body lying on top of it) it loses most of its insulating value. The deep grooves of the Klymit pads are designed to allow the sleeping bag to loft and provide insulation to the body. Most of the other pads only have shallow depressions which limit the lofting (and therefore the insulation) of the sleeping bag.

I have to give a plug for the Klymit V UL insulated. It's been my go to for winter camping. One of the things the this video (great video, BTW) doesn't take into account is that the ridges are designed to create spaces for the loft from your sleeping bag to fill. Keeping the bag "lofty" increases its overall insulating properties. When a bag is compressed against a flat surface, it will loss some of it's insulating power. Thus, by creating ridges, you lose some insulation from the pad, but gain it back with your bag.

hands down the most comfortable for me is the Nemo, it tried several of the others including sea to summit and it was a no go. The tensors I beams are just far and away the most supportive and comfortable of the bunch. Im pretty sure the xtherm has BOTH the reflective materiel as well as a layer of synthetic fill which is why its a 6 r value and also retains the heat as you showed. Its a bit of an apples to oranges comparison there with that pad vs the others as they arent designed to do the same thing. A much closer comparison would be the nemo alpine version of the tensor. Great work on this, and great examples!
@GearTestTV3 жыл бұрын
I haven't reached out to Thermarest to confirm this, but their website listing for the Xtherm emphasizes that their design does not have the same issues as down or synthetic insulation, so my understanding is that the Xtherm does not contain any lofting insulation. The Tensor is great though! Haven't had a chance to get my hands on the Tensor Alpnine, but I'd love to compare it at some point.

Hello... Very interesting and well-done video... I'm retired and I hike a lot with at least a 7 to 10 days trek per month...To me, after all of these years, I only use now 2 to 3 superposed foam mattresses. The real problem of all of these 'inflatables' is that at a certain point it will be flat because of a hole, a melted side that leaks, the valve, patch that don't glue enough, long and hard to inflate especially on high altitude etc... I spent a lot of money in all of those, including military ones... My foam mattresses are big, make a big roll over my backpack, but they are light enough, insulated enough even in frigid temps, i'm all set in seconds, they make no noise at all, I saved a lot of crazy money and it works good nights after nights after nights. I also saved a lot of nerves spent insulting my 'deflated' inflatable mattress in the middle of the night at the top of a mountain during a freezing night, one after the others... Like that, I enjoy much better backpacking without problems...And I sleep well!

Loved your video and your methodology. I have 2 of the Static V Insulated Pads (different than the ones you are showing) and one has the older valve like you have and the second one I have is with their new valve system. The reason I have 2, is because my pad with the older valve made the same noise as yours and it sounded like air is escaping so I contacted Klymit and they sent me a new one with their new valve system and let me keep the old one and sure enough there is no noise on the new one. I think the air was only escaping within the pad and not out of it, but my point is it could be because of the old valve even though it doesn't sound like the sound is coming from it, but more importantly, Klymit was great to deal with and had amazing customer support.

Not necessarily. The water line for our clothes washer runs through our garage space. Its insulated but if our garage gets below freezing (rare) then the hot water line freezes up but the cold water line does not. It’s called the Mpemba effect. Since the human body is mostly water a small badly insulated area could see similarly larger amounts of heat transfer than the average insulation amount would lead to. Not the same mechanism necessarily, but if it happens with water your skin is 2/3 warm water. That’s a lot of heat transfer material.

Just a note on the Klymit UL SL...I have one and used it on a trip in Utah's High Uintas Wilderness in late August where we got a night that made our camp really frosty and froze our water bottles. So nighttime temps easily got down to 25-30 Fahrenheit which was roughly confirmed by a keychain thermometer I carry. I didn't feel a chill at all sleeping on it. Why not? Because my 20 degree down bag lofted enough under me to fill those gaps where those welded seams are between the baffles on the pad. It is actually designed for that to happen. So...While the Klymit may not be a true 4.4 under the new standard, I think it could definitely be very close as shown by your test when used with a lofty sleeping BAG and so it certainly works well for 3 season use with such a bag and even 4 seasons in most southern regions of the country. I would NOT use it with a QUILT, as your test shows that would be risky in colder temps. I do also slip my sit pad under the pelvic area to protect my hip in case I do end up bottoming out with it when using it but haven't had it really happen yet. I also use a trash bag inflator I made for it to minimize warm moist breath going into it. Oh, and I also get the occasional squeak with it. Was worse out of the box, but very infrequent now and doesn't seem to occur when it's all settled out. It's a fine pad for those who don't have the budget for the more premium brands and models. That all said, I did pick up a previous model of the standard NeoAir on clearance last year and have been favoring that for its additional weight savings. Also just got my wife the women's version of the insulated Ether Light because she hasn't been a fan of the horizontal baffles of the old XTherm she'd been using. That Ether really is plush and comfy! Now...I would love to lay on a Nemo sometime to see how it compares in comfort.

I don't have and don't like the Klimit mats, but there's a catch with the V shapes that they use, as someone with a sleeping bag will have some of the sleeping bag insulation fluff up and fill the grooves between the V shapes, thus adding some warmth to your back.

I have three ther-a-rest sleeping pads (uber light, xlite, xtherm) I started with just the xlite but got the xtherm for winter and the uberlite for summer backpacking. I found that I use the uberlite most of the year. If the night temps are going to drop I found that I need the xtherm (that cold really sleeps through!). I rarely use my xlite anymore. My xtherm has kept me warm in below freezing & when snow is falling (and I get cold easily). Never have regretted the high cost. I don’t have a problem rolling off it (even sleeping with my dog) as my sleeping quilt & sleeping bag both have clips so they stay on top of my sleeping pad.

I'd for sure want to see this kind of video comparison done with the self-inflating sleeping pads. I'm curious to see what the differences will be; I have a sneaking suspicion there's a possibility of more thermal transfer (due to the interior expanding filler). Regardless, I'll keep an eye out if you get a video posted for the self-inflating genre of sleeping pads. Cheers

Also, I am glad you mentioned ground temp vs air temp. I used my BA AXL (uninsulated) over the summer in the Sierras, and it got cool in the evening, 30s-low 40s, but had no issues staying cold. Fast forward to December, I hiked out i. A local area where the temps have been hovering around 30s-40s all day, and low 30s at night. The ground was colder, and I was doing crunches all night to stay warm.

I got the Klymit UL insulated and froze my arse off where my hips and shoulders did not have any support while side sleeping. It was about 3-5c outside, in an OEX Bobcat, on grass, with a Mylar blanket underneath, I was using an 850 fill down bag. I would recommend this mat for summer use only.

How does a foam pad added under the air mattresses add to the overall R-values? It would be interesting to see the before and after on the thermo camera. Always wondered if it would make a difference on top the air mattress or on the bottom next to the earth.

Howdy, when Winter camping on top of snow, my wife and I use a combination of Thermarest Camprest, on top of a Ridgerest foam pad, and have found, with a good sleeping bag, that this combo is excellent for keeping us warm and toasty! As an aside, I do find it interesting that most "testers" do not mention the older, slightly heavier self-inflating Thermarest pads. They work, pure and simple, for three season backpacking and camping, and with the addition of a wide Ridgerest pad underneath, do very well in snow camping, too! Works for us, anways. - Doc

Great video. Since the past 2 weekends, both well below freezing, I've been trying to talk myself into picking up the xtherm.$$$$. My R-4 Big Agnes has been cold even with foam underneath. It may be the size, a lot stocks out side of my quilt. I'll miss the 4" but I'll enjoy the warmth. Invest in sleep.

Like you, I have the same two Klymit pads. They were my first ones and worked for what I was doing. Over time, I have developed into a side sleeper and have found the Paria Recharge XL (76 x 23 x 4, 4.7R, 26oz, $85) works best for me. I cannot sleep on a firm pad and the 4 inch thickness allows me to have a softer pad without hips or shoulders hitting the ground. I have used it in the mid 20s with my SD 20 degree backcountry bed and stayed plenty warm, actually a little too hot at one point. I wish I would have known about that pad before buying the other 4 I have in my basement. It's amazing how much money we waste on gear over time.
@lakorai23 жыл бұрын
The Recharge XL is the most comfortable pad I have ever purchased. The Nemo Tensor Alpine was a close second, but its 20d face fabric is fragile and pops easilly. The Recharge is songood that I also bought the DW version for when my wife and I car camp. For winter I found the ReCharge's R value however to be a bit lacking since I sleep cold. For winter camping the best pad I have ever used is the Exped Downmat XP and UL. This is fantastic as they have r values of 7 and 8 and unlike the Thermarest Xtherm it is a slow heat gain, rather than the raging heat from the Xtherm. The Expeds also have a superior valve system and are 3.5" tall; way better than 2.5 on the Xtherm. Thermarest is super noisy and I hate the chip sound. Returned that immediately to Moosejaw after inflating one time.

Aaaaaaand subscribed. That is a VERY thorough pad review. WOW! I own the Drop version of klymit insulated pad. Pretty good. I think the idea behind the space between baffles is that it allows the down in your bag to loft and fill the space. Not sure if thats how it actually works in practice and of course a quilt would negate this feature. However, i've never felt cold in mine, down to about 5 celsius anyway.
@dkeener133 жыл бұрын
I think that's right, and that the Klymit pads might work better with a bag than with a quilt because the insulation can loft up in those gaps. I've used one with a quilt and I would say it was a terrible performance.

@larrydonna3693 жыл бұрын
Hi, I think another consideration is whether the pad will be used with a sleeping bag or a quilt. The klymit static v is warmer than you would think because the deep groves seem to allow the sleeping bag to loft in the air pockets beneath it. I've used this in the mid 20's with a 15F bag and was toasty. I would not recommend that temperature with a quilt unless you can get the quilt underneath you.

Great review. I would agree with you so much from experience also. I had a Thermarest and sold it, it was intrusively noisy and I rolled off it all the time. I use a Nemo Cosmo (primaloft insulated) for Kayak Camping and an Exped Downmat HL Winter for the winter backpacking. The Nemo is hands down the most comfortable pad I've ever used. I'm a big fan of Cascade Designs products, but not Thermarest Pads.

I'd love to see you do a test with multiple mats, (close cell with a air mattress, maybe reflectix and an air mattress, etc). I would be curious to see which one is better next to the ground and/or which ones would be better next to your body. You have a great channel keep up the good work 👍👍
