[@peterfconley]

Dude, the capacity measuring you did made my day. I’ve always wondered if those figures were nominal or actual and it was SO satisfying the way you did it!

[@MyLifeOutdoors]

Glad you enjoyed it. I was surprised at how tall each pack was when “full” I don’t think you could actually hike with them that tall.

[@peterfconley]

@@MyLifeOutdoors that was always my hunch. I’d be curious to see a breakdown on capacity with the top closed and what percentage of nominal capacity that is.

Nice review. I like how you put the bloopers at the end 🙂Currently I'm using the Osprey Exos Pro 55 and still happy with that. Slightly heavier than the "ultralight" but that trampoline back is really great for ventilation.

[@mattbeckwith8575]

I’ve had the regular Exos 58 for a few years now. Still under 3 pounds, carries weight nicely, and the trampoline back saves me from a lot of sweat. I think eventually I’ll move up to the exos pro, it looks great!

It is hard to know what is going to be comfortable until you actually try a pack, and know how to adjust it! That said, I have a Kakwa 40 that is by far the most comfortable pack I have ever used, and I have use many!!! It does not allow any airflow on the back, but for me, that is not a deal breaker when it is so wonderful to wear. Awesome review, keep them comming.

That's intersting the 55 is not the same fit. I literally forget I have my Kakwa 40 pack on most of the time I am hiking. I just can't say that for any of my other packs.

[@Pasequale100]

[@damiano_damiano]

great video thanks 🙂 I have an Osprey Exos 38 which without the brain (which is actually removable) weighs just 1 kg (2.2 pounds). An ultralight backpack to be worth calling ultralight must be at least weigh around 0.5 kg (500 g / 1.1 pounds): that's why I went for the Liteway Eq. 35 Liters, with its 420 grams (0.92 pounds) seemed the perfect choice! Unfortunately the Osprey Exos 38 is much more comfortable anyway... and at the end of the day 500 g / 1.1 pounds is equivalent to half a litre of water... in my opinion the gain in lightness is not worth the loss in comfort.

[@RayHikes]

With the gossamer gear, if they say it's a 60L pack, they're measuring EVERYTHING. I have a Kumo 36 from them, and the internal volume of the main pocket is only 28L. The other 8 liters are in the front mesh pocket, and the side water bottle pockets. I love the packs but wish they'd be more up front about how small the packs are. Although, the lack of space did force me to go more ultralight, so maybe Gossamer is just trying to get us all to be more UL? Edit; Just looked it up and gossamer gear only claims a capacity of 36L in the main pocket of the mariposa. They say there's 24L spread across the exterior pockets.

[@seattlegrrlie]

Man, I hate this. I know people like pockets, but they drive me nuts. I don't like to spread my stuff into multiple places and the size of the pocket is always wrong so what you want to put there just doesn't fit. This totally kicks this pack off my list

[@JimHep]

I bought my HMG second hand about 4 yrs ago. I usually come in at around 27-30 lbs all in (gear/food/water). I honestly really like it. 🤷‍♂️ No back pain which is something I have struggled with in the past. I do pack it in such a way to add to the structure of the back, but I think that is a recommendable on most of the UL packs. One of the “odd” features that I really like about the dyneema packs is their ability to maintain structure when empty. I have always like a simple duffle/bucket style pack that holds its shape when empty. I use one large pod for my quilt and a smaller pod for odds and ends.

[@frstesiste7670]

Always wanted to do a fill with water test, but kind of impractical in a condo without even bathtub for protection if anything go wrong. Great test!

[@MyLifeOutdoors]

Trust me…lots went wrong on this one…each pack was about 120 lbs once full. Very hard to keep up right And when you dump it there was no controlling the water…

[@markswishereatsstuff2500]

I have an Atom Packs Mo40. Has a sturdy removable hip belt. Load lifters and I think it weighs around 28oz with one zippered hip pouch and Chicken Tamper water bottle carrier on the shoulder strap. I got funky colors to make it one of a kind.

[@jadenm]

Great video. I absolutely want to get the arch haul but, like you said, the price is the barrier and buying the hip belts just makes it that more expensive. Those load lifters make a huge difference for me. I tried two different sizes of the hyperlite and wanted that pack to work. It checks most of the boxes for me but in the end, shoulder pain caused by the straps were too uncomfortable after a few hours of wearing it with 20lbs of gear. No matter how i adjusted the frames, it just wouldn’t work for me. Magic straps really are magic to my backpacking experience. 🎉

[@markjones127]

In the UK we have a brand called Montane who do an 'almost' ultralight pack with the running harness set up, it's called the Trailblazer and I have the 44L version but it's a Tardis, I can fit my tent in one of the side pockets for example meaning it leaves the 44L main sections free, and the design means it has compression straps which double up to hold my tent in place, I don't think it was even designed to be used that way but it works for me, it's 2.16lbs and all their gear is designed more for fast hikers and mountain runners, the back length can also be adjusted with an easy to use Velcro adjustment system, I love the running pack style shoulder straps with bult in pockets though.

[@antoniolaza736]

not from uk but second for this, can't wait to get it delivered so I can put it to test. After long thorough research for a budget friendly, framed, adjustable and ultralight pack i bumped into the montane 44, from that point couldn't find anything which could justify the extra price for what it offers, less than 120E, what could i ask more for. I'm aware of certain downsides presented by others but willing to take them. How is the overall durability of that pack though, sewn failures or ripped material (excluding the mesh thing, that's kinda obvious for any pack). What about the frame, is it holding well? Padding comfy enough (we talking about ul, so a total weight of 10-12kg)?

[@cornflourr]

Yes I have the montane 44L backpack too and it’s SO comfy!! I wore someone’s Hyperlite Unbound 40L pack for a section of the hike and was immediately in pain on my shoulders. The montane is actually a very similar weight to the Unbound 40 but with way more comfortable features

[@chrisholiman2552]

I took that Hyperlite on a trip and loaded it with about 35 pounds of food and gear and it was horrible. The cheesy belt would not stay on my hips and my neck and shoulders were destroyed after the first day. I believe the rating for that pack is 40 pounds, but I wouldn’t put much more than 20 in it. I traded up to a heavier pack with belts that actually cup the iliac crest so the weight stays on the hips. Well worth a couple of extra pounds.

[@randyholloway920]

HMG is the facade of UL backpacks. They are all too heavy and over-priced for what functionality orfeatures they have. That’s why they’re called Meh packs.

[@zero11010]

Really neat idea! Rather than wasting so many gallons of water (I'm in a state with frequent water shortages, so I think about it a bit) you could use a syphon to transfer water from a filled bag to an empty bag. You can use gravity to do the trick and not have to worry about buying anything (other than a few feet of tubing). And, you can use the weight of the water to measure how much you have in a given bag. A liter of water weighs 35.27oz. So ... 55L of water weighs 1,939.85oz (plus the pack and garbage bag weight). Totally not very important. Most areas have plenty of water and I imagine it's only 60 or 70 gallons to do this for a series of bags in each video. Still, you'd be able to cut that dramatically if you were interested.

[@philipkitamura2870]

Like the 6 Moon Designs Minimalist V2, Mystery ranch Bridger also has a vest design also in 50L. I haven’t heard of the 6 Moons pack till today, so it’s great to hear there’s more of the vest designs popping up!!

[@SultanofSpey]

I always hike alone because the very reason for hiking is solitude, not community. I don't bring a phone. I bring an ACR RescuLink which I predict I'll need someday. I don't walk all day in the rain to get somewhere "down the trail". I pitch a tarp, make coffee, and listen to the rain hitting the tarp. I carry a real toothbrush and use it three times daily. My 65L Mystery Ranch TerraFrame weighs over 5 pounds, my 80L version weighs over 6. I wear boots, not sneakers. I change my socks everyday, sometimes twice a day. I like to wear clean clothes at least every 4th day on a 1-2 week outing. I carry first aid items items well beyond the 99 Band Aids and single alcohol wipe found in the venerable "Adventure Medical Kit" in the yellow bag. Sometimes I carry bear spray. Sometimes I carry a firearm. Sometimes I carry both and I know how to use both. I carry a 3" fixed blade knife that is practical and razor sharp. I also carry a small SAK becuase it was my grandfather's. Sometimes the zippo in that same front pocket doesn't work but I don't care because it too belonged to my grandfather. While I do strive to cut the clutter and bring dual use items, I always build redundancies into every critical system I carry such as fire, shelter, water procurement/disinfection, signal, and navigation. I'm not an ultralighter and I know I'm not one of the cool kids because of that. But somehow, I find the strength to carry on each day...by myself, alone in the woods.

That Bonfus is so ultralight, you couldn’t even see it in the original lineup! Love this overview. It’s funny how misunderstood this class of packs are to those who don’t have experience with them. I’m one of those weirdos who hasn’t even put on a “traditional” pack in years. I believe the pseudo-standard for pack capacity testing is ping pong balls, oddly enough. Also, most pack makers list the internal vs external volumes of their packs. It is all over the place! From their websites: Arch Haul: 50L (37L main body, 2.5L each side pocket, 8L center pocket) Southwest: Internal 55L, External 9.8L Mariposa: Main Pack Body to Extension Collar Seam 36L, Spread Across 7 Exterior Pockets 24 L Minimalist V2: Body 2441 ci | 40 L Extension Collar 550 ci | 9 L Exterior Pockets 610 ci | 10 L Kakwa 55 Internal Volume (S / M / L) 43L / 46L / 49L - External Volume (S / M / L) 15L Framus 50L internal volume, 8L external pockets

[@MyLifeOutdoors]

I should have gone looking for this info. Based on my test it all sounds pretty accurate except the Minimalist and the Mariposa can both hold much more than they claim. But they might start getting top heavy.

[@jpriddle]

@@MyLifeOutdoors Re-reading my comment, I meant to say the measurement standards are all over the place. 😃

Should have added the load carrying capability. It matters especially on water carry. Not everyone can go from water source to another two times a day.

@ Yes! Weight capacity is very important, too. As a frequent desert hiker, I can relate.

@@jpriddle Just filling 15 litres of water bottles for a 3-day desert hike. That’s 33 lb + gear. 🤜🤛 Edited: with only gear I could make it work with 38L pack but for load carrying capacity, I’m taking a 75L one.

[@debbilermond1553]

Steven, thanks for this well thought out video for people considering upgrading their backpacks or even purchasing their first one. So much to consider, your visuals and explanations should really take the mystery out of what packs to buy. I bought the GG Mariposa 60L for myself and my husband from GGG. We love these UL packs for the external pockets to grab needed items instantly and shaving over 3 lbs. off the weight of our Gregory Diva and Baltoro 60L packs. The only thing I don't like is the way the top clips down in the back of the pack. That was probably why you couldn't get it to close. The top pocket is difficult to get into when the straps are cinched down tightly. Other than that, we're both quite happy with these packs. We buy a lot of interesting things on GGG. Love the little collapsible Fozzils Bowlz. Now, we have a plate and bowl all in one and it takes up next to nothing as far as room in the pack. Also, cleaning is a breeze when you unsnap it to rinse it off! You can go wrong for cottage industry innovation than Garage Grown Gear, IMO! 😉👍

[@peterjohnson6273]

Always informative, often funny. Thanks Steve.

[@Rambling_Bob]

The “arc” on the Zpacks packs is great for ventilation, but it also has a downside … the more arc you put on the stays, the lower the pack’s internal capacity. I’ve just upgraded from the 55L Arc Blast) to the 70L to recoup the internal space lost to the curving stays. Either way it’s still a great pack 👍

[@kevinstarski1598]

Thanks for pointing that out. Used to have an Osprey daypack and it was so "shallow" that once I put in my water bladder, I had a hard time putting anything else in there...plus I wish the 70L would have more padding on hip/shoulder straps than the smaller version since they carry more. It still would be an ultralight pack anyway

@@kevinstarski1598 Sounds like my Stratos 24. Once I mostly stopped using bladders it became more useful, but the hip belt is still too short. I’m not “one size” like the pack LOL.

[@PSnGa]

I've been using he HMG for years. It's more expensive but it's CF. That makes a difference. It lasts longer, is more water proof and holds up to abrasion very well. As long as you aren't loading 40+ pounds (hello, ultra LIGHT...) it's an amazing pack. I've also got a zpack arc haul for my son and it likewise is fantastic. I wish I had one that would fit me to try the "arc" system. Next pack I get might be a zpack for that reason. No matter what, I'll be getting a pack made from CF.

[@philsmith2444]

Yes, but part of the blame lies with HMG for stating that the Southwest 40, for example, can carry up to 40lb. Physically, yes, but in anything resembling comfort for the hiker? Probably not.

[@hanwagu9967]

@@philsmith2444 the tensile strength of the materials far exceed the stated pack load capacity, so it's designed, if properly fitted and worn, to carry up to 40lbs comfortably. First, you have to define comfort, which many people in this ultralight world means that if it feels heavy it's uncomfortable. Heavy isn't uncomfortable, it's just heavy. Second, I could on and on about how many videos and pix of ultralight hikers I've seen not wearing packs correctly or wearing improperly sized packs. If you aren't properly wearing a pack and/or it's not fitted properly, of course it's not going to be comfortable. With that said, if a pack isn't comfortable up to the max load, then you probably ought to try a pack from some other brand if the target load is up to the max load. HMG's design isn't going to fit properly thus comfortably for everyone, just as another brand's pack won't.

Great video! I’ve been using expedition packs for the last two decades because they haul loads well, every single item can go inside (I hated the days of strapping a lot to the outside), and I can choose how full I want it. However, there’s a high likelihood that my old “strategy” will change when I do the PCT, where a lighter and more agile pack is looking more probable. Some great information to consider here.

I love my Mountain Laurel Designs Exodus. I ordered a second one with no hipbelt. The shoulder straps are bigger than most UL packs. It is comfortable with about 22 pounds though I usually start a section with about 19 with 4 days food and 1 liter of water. Load lifters are not needed for lighter loads. I started hiking with a giant Lowe internal frame pack that was over 6 pounds. Because it was adjustable it was so comfortable and the weight transferred to my hips. But 45 pounds was still 45 pounds. Now my big 3 pack, sleep system, tent, and #4 my cook system come in at less than 6 pounds. You can't expect to carry heavy weight or mid weight in a ultralight pack. I assume the pocket volume is included in pack volume. It's all part of the pack.

You bring up some great points in this video, and I'll happily eat my words. I still stand by my dislike of the price tags, though!

[@MyLifeOutdoors]

Haha. No offense taken…but I didn’t make these packs. I guess comments stick with me more than I realize. Thanks for the video idea

[@davidwilkes3966]

I would like to offer two comments. Having features you don't want/need is not the same as skimping on features. For example when I purchased an HMG (Junction) it was in part because it was very water resistant and I needed a pack that could survive being repeatedly tossed off to the side of the trail into brush , rocks, dirt, etc (a frequent occurrence during trail work projects), also as I find the HMG pack does not need load lifters, so not having them is, at least for me, a feature, not a lack thereof. It has been my experience that pack manufacturers measure volume differently, some only count the main compartment while others might include the external pockets and/or 'brain'. I am not going to try to say which is right, I just wish manufacturers were more transparent about it so purchasers were better able to compare apples to apples. It was one of the things I spent way too much time and effort looking into last time I purchased a pack.

[@gregvanpaassen]

Had several packs over the years, starting back when Cordura was the leading edge in advanced textiles. Currently using a Kakwa 55 in medium. It's perfectly fine for up to 16 kilograms but 19 is too much. Not the most comfortable pack I've ever had but among the best (with an almost-deflated air mattress as lumbar padding). Surprisingly tough and durable, except for the velcro for the frame pocket. I considered the Atom Packs "The Mo" before buying the Kakwa. Perhaps I'll get one to try... Another (not quite ultralight but impressive) pack is the Osprey Exos Pro 55. My step-grandson now has one of those. Load lifters are a must for me, but my wife now has both sizes of the Southwest and loves them. And it's amazing what comes out of them when she sets up camp!

Just saying!

[@ropersix]

A fun capacity test, and one I've contemplated doing myself. However, for those who may not know, different companies measure pack volume differently, by including or not including all the outside pockets. Six Moon Designs, for example, claims the Mariposa's main body is only 36L (up to the extension tube), and then adds on the volume of the outside pockets to reach 60. Dan Dursten makes a general claim of about 15L for external pockets, etc. So you do have to do some research, to figure out if a pack will hold what you want, the way you want.

Load lifter straps, whether or not they actually do anything, are included when the take off points of the shoulder straps (e.g. where the shoulder strap is fixed to the back panel of the backpack) is lower than the top of the back panel which should be approximately parallel to the top of the shoulder for proper sizing. load lifters on non-rigid frame packs like the mariposa 60 aren't doing anything to transfer load, they are simply deforming the top of the back panel of the backpack. it's only because the shoulder strap take off points are lower than the top of the back panel that those packs include load lifter straps, which is basically compensating for a design choice rather than actually doing anything in reality.

i'll take my extremly comfy ossprey any day of the week, love the reviews though!

[@JasonSnailer]

Thanks for your video. I’m making loadlifters for my Hyperlite before my next thru hike in March. Fellow Texan here in dfw btw

[@HitechProductions]

I have a granite gear vapor trail that I really like. I weighed it at 32oz and it was only $60. That was used, but it gave me the courage to modify it to make it perfect for me. :^)

[@johnphillips3526]

Nashville Packs does the running vest straps better than anyone. Most comfortable pack I’ve ever used and weighs just over a pound. Pricey though.

[@mitchellyork2890]

Have you checked out any of the packs offered by Granite Gear? I have used the Crown3 for the last 2 years and it is the perfect hybrid between traditional and ultralight. Granite Gear also carried a ultralight pack as well. Would love to see your feedback on their gear, thanks!

[@midwestmikeonahike]

Sure hope that water didn't go to waste! Curious why you didn't include the Flash 55? Definitely lighter than some of the ones you profiled.

[@MrJimaki]

I always wondered about the stated capacity. Great video

[@Mainostus]

Thank you for adding the weight also in metric! Love from 🇫🇮

[@PSYCH022]

Great review of these packs. I think one really good option is missing from this list: Granite Gear

[@philsmith2444]

Yes, my Crown2 38, Crown2 60, and Nimbus Trace Access 70 have me about ready to send my Ospreys to new homes. All I need now is a NTA 85.

[@Peeeeeew]

For my needs i found out SR Flex-Capacitor 40-60 to be the best, with weight of 2 lbs 10 oz. (1.19 kg), serves me well over 2 years now, no cons at all. Ukrainian Carpathians are rough in winter, so extra capacity helps a lot with bulkier warm gear.

[@festorfamine]

Left out the pack that's the most popular on all thru-hike. ULA circuit.

[@CindyinNewMexico]

I have an Outdoor Vitals Shadowlight 60 that works great for me. I haven’t seen anything else that I would switch to, especially for the price.

[@galinswigart]

I can't speak to it from experience because I haven't purchased a pack without load lifters, but I cannot imagine liking that design. Regardless of base weight, load lifters are critical to properly transfer weight and keep it close to the body. How ever many ounces they add to a design, they are worth it.

[@wisenber]

"Regardless of base weight, load lifters are critical to properly transfer weight " If you don't have much weight, there's no need to transfer it.

[@galinswigart]

@@wisenber that’s not completely true, although if you find it comfortable, I’m jealous of you. Even 10-20 pounds on your back needs to be properly positioned close to the body, with no load lifters, why have a frame or waist belt? Seems to defeat the purpose. Not to mention, even with a very low base weight there are times where longer water carry or extra food for longer trips are inevitable and packs get heavier. I will take the extra 3-5 ounces for load lifters 100/100 times.

[@wisenber]

@@galinswigart It is true. For most people, 10% of body weight and under doesn't require an elaborate suspension to manage. If anything, a rigid or tight pack makes it less comfortable to carry. In the summer, I generally just use one shoulder strap with no thought of a hip belt, let alone load lifters. It isn't until I'm hauling a winter load or a bunch of trail maintenance gear or an elk quarter that a suspension comes into play.

[@mikeypick1]

It’s still very comfortable… I think it’s the same fit but maybe the extra size feels slightly different. I can’t put my finger on it yet, but it’s just not quite the same “OMG I LOVE THIS PACK” feeling as the 40.

[@natlovell122]

I’m rocking a Mountainsmith Scream 55 I got for $88 on sale. It’s a little under 3 lbs and comfortable.

[@davidminor6537]

Love the water-fill volume verification!

[@ImGonnaMake]

I'm a sweaty boy, so back ventilation is non-negotiable with my pack. At 41 oz. and $250, the Gregory Focal 58 has been serving me well for a couple years now.

[@erueru2014]

I have tried different ultra light packs, and they have their use. But on most of my hikes I have to carry food for 14 days and can not get my pack under 15 kilo (33 lbs), and when you are build like a skeleton like me it quickly becomes very uncomfortable, so I use my trusty Atmos AG 50 liter, it's a bit heavier but the comfort is so good that it's worth it. On hikes with 10 kilo (22 lbs) or less I will use a lighter backpack.

[@jamesbramlett5407]

❤ my Kakwa 44 - it's almost perfect for

[@Pasequale100]

the frame of the kakwa doesn t hurt or cause any pain?

[@jamesbramlett5407]

@Pasequale100 its like an inverted U, just around the perimeter - maybe a 1/4" rod. It really makes the pack what it is. I don't feel it at all, other than the stability.

[@Pasequale100]

@@jamesbramlett5407 thanks a lot!! My torso is about 46cm plus/minus 1 cm. And i am 173cm tall, and a little wide/ muscular. What do you think which size could fit me? M or S?

[@jamesbramlett5407]

@Pasequale100 definitely the Medium, thats perfectly sized. Can't wait to hear your experience here in a couple weeks after you get one! They're truly awesome, sooo light yet strong and with the Large, it means 44L so that's more than enough for a few nights. I got mine over a year ago, and am still in love with it.

[@sushisacha111]

Would be interested to know if you had considered Atom Packs The Mo at all?

[@GrandeLoutre]

SMD is not the only one to make vest strap framed backpack. I don’t it too at Atelier Longue Distance and it is true vest straps 😁

[@JellyFlavoredGerman]

How many grams would you save if you shaved your beard?

[@DanielPetukhin]

Best way to present your sponsor I've seen thus far. Creative! Great vid - as always!

[@natehoover5266]

I've only been backpacking for 3 years. I bought the REI Flash 55 first and I love the water bottle pocket. Super underrated feature imo. Then I bought the Kakwa 40 when it came out and it's pretty good but barely big enough for me. Both of which I thought could have bigger mesh pockets. Maybe the Kakwa 55 is a better option but I'd love a Zpacks or Mariposa. Which of all these in the video has the biggest mesh pocket?

[@Pasequale100]

the frame of the kakwa doesn t hurt or cause any pain?

[@natehoover5266]

@Pasequale100 no I've never felt the frame

The ultralight craze is interesting and drives some cool innovations, it's similar to fashion shows though. Very little of it is directly useful, just interesting ideas. Do some squats, carry what you want to have with you.

[@philsmith2444]

I see videos all the time where people bring stuff solely because it’s UL even though it’s useless. Example: bringing a Gossamer Gear 1/8” thick closed-cell foam pad for extra insulation in winter or in case their main pad springs a leak. First of all, it has MAYBE a 0.5 R-value. “But it’s UL!” Yep, UseLess. It’s wasted weight and bulk. In winter - REAL winter, not deep south winter - or high elevation, if you’re worried about your pad leaking or not being warm enough you need a second pad with high R-value, not something that lets you stay under some arbitrary number.

[@Sugar_bug]

Please review the new REI flash 50. I believe it is only 1 pound 11 ounces

[@nzadventurer]

Awesome video. Great technique for volume tests 👍🏼

[@jhosk]

What about outdoor vitals? They have packs that are sub 2 pounds, have better suspension, including hip belts and can carry a heavier load. And are around $200

[@ItsAStephanieB]

Love your channel. It's interesting and different. Thank you for the effort!!

[@IdRatherBeHiking]

I'm curious why you didn't say anything after filling the Gossamer Mariposa 60 pack. Its just a hard cut without verifying its 60L. Reason being that pack is only 36L internal, its a sneaky marketing tactic by Gossamer gear (36L internal 24L external storage) and if someone buys that pack now from this video thinking its 60L internal they are probably going to be pissed.

[@MyLifeOutdoors]

I cut because my mic crapped out on me and I didn’t have the audio. That said there was 60 liters of water in the main compartment and it almost closed but not quite. I think it would have with 55l in the main compartment. So 36l is a very conservative measurement.

[@justjonoutdoors]

One of these days you need to review the OV Shadowlight - my Shadowlight 60 is my favorite pack for many reasons.

[@LeoJohann]

The MEC ul serratus 40l also has the chest harness and it’s probably the most comfortable bag I’ve ever had

[@VincentGilligan]

I’d have a hard time switching from my Osprey Exos 58L. Only 2.7lbs (1243g) and 2.4lbs (1105g) without the lid. It’s extremely comfortable and has amazing ventilation on the back.

[@oscarcan-ammotocicletta148]

Hey! Have you already tried out the Durston Kakwa 55 Pack? I think about buying this pack together with a ZPacks Duplex Zip, for my 3.000 km. Te-Ararora journey through New Zealand this year!

[@ericb.4358]

-> I'll take my EXOS 58 (actually 60 L. in size Large) at 2.84 pounds. VERY comfortable! Plus it has a tubular frame like the DURATON pack AND a "trampoline mesh back like the Arc Haul. ** Frameless backpacks are as stupid as strapless hiking poles.

[@billseay6399]

Me to.Hey thanks great info love it big guy

[@katejam4223]

I really appreciate that you put up metric conversions, but might want to check your sums on the ‘just over 3lb’ Six Moon Designs, it’s way more than 889g :)

[@MyLifeOutdoors]

I think some of my titles got switched and I just didn’t catch it

[@durstongear]

Smart way to measure volume. Way better than how I do it.

[@MyLifeOutdoors]

Now I’m curious how you do it? Someone said I could have just weighed it. I didn’t think of that.

[@durstongear]

@@MyLifeOutdoors The classic DIY method is to fill the pack with some type of non-compressible item like beans, golf balls, etc and then pour those items into a box and measure the L x W x H to calculate volume. I recently did this using gravel. Prior to that I just measured the full pack to get the height and top/bottom circumference and calculated from there. Calculating it is problematic because packs aren't totally round cylinders but more of a blob so you overestimate some. I think the gravel is more accurate but still could get error from the multiple steps. I like the water method. It would be good to verify if the gauge is accurate (e.g. flow a gallon and see if it really fills a gallon). If the gauge is accurate it seems great. A bathroom scale would work pretty well, but you might fry the scale if you spill water on it, and some packs might not balance on it very nice. Could also use a 1L scoop to see how many fit but that sound tedious. While the water methods can give a precise measurements, there is the caveat that water is massively heavy so it could actually be stretching the pack by a meaningful amount. Fabrics like DCF and Ultra aren't going to stretch much because UHMWPE won't stretch more than about 2-3%, but a nylon pack (e.g. Mariposa) might actually stretch larger by 5-10% with >100 lbs in it. Ideally the liquid used for the test would approximate the weight of a full pack (e.g. 35 lbs). Liquid methane is about the right density - could be a fun video trying to do that without it turning into gas and stinking out the neighbourhood ;)

[@TheNypenfan]

One of my gripes with packs is that you really need to read the descriptions to see how big it really is. My ohm 2.0 is 63L, but the main body is 34L, and the rest of the pockets add up to 63. Works well for me, but something you need to know. So the arc haul by comparison would be a total of like 80L if they measured the same way. It’s confusing.
