    A cloudscraping klettersack.

    Head for the high ground with the Patagonia Ascensionist Daypack 35L - 2136cu in. Designed for cragging on mixed terrain, ice, or rock, and sewn from a lightweight but rugged combination of 6.5oz 210D and 400D double-ripstop nylon, it's an excellent all-around climbing accessory. The single aluminum-loop frame, with a trampoline mesh center panel, is contoured for comfort and ease of movement and can be easily removed via a hook-and-loop closure to shave weight and add additional flexibility. The spindrift collar features an integrated lid secured by a heavy-duty aluminum hook and adjustable webbing strap, for varying-volume loads. And a secondary inner rainfly collar provides additional weather protection and acts as an expansion panel. Side compression straps quickly and easily adjust on the go to lock down the load, and also secure the upper shaft of your axes. The sheathed axe carry keeps the axe heads securely out of the way on the approach, and locked into place until they're called for. The ergonomic shoulder straps feature lightweight padding and load lifter straps, and the custom hipbelt features removable padding to easily transition down to a lean webbing belt, or can be removed entirely to save additional ounces. Four rows of daisy chains add external attachment options, from crampon attachments to a vertical ski carry, and a zippered lid pocket stores small essentials. A one-pack quiver,the Ascensionist is built to support all your high-country adventures.

    Great for climbing and hiking

      This pack is fantastic for single and light multi-day outings. It is light and can carry most of the essentials. It is also quite durable and can handle regular use for climbing related activities.
      I would not recommend this pack for carrying ski's however. The light fabric tears easily against the sharp ski's. I had two holes on either side of my pack after carrying ski's vertically for only an hour. Patagonia repaired the pack for free which was great, but they should not recommend this pack for skiing, its too fragile/lightweight.

      Good climbing pack

      • Familiarity: I've put it through the wringer

      Pack was great for a car2car of Mt Stuart's North Ridge in WA state...light but held what it needed to hold...I'm super rough on gear, so not surprised to see some holes/tears after a summer of use--but I do wish the material was a little stronger, keeps it from 5 star...good pack though--you won't regret purchase.

      Perfect Multi-tasker

      • Familiarity: I've put it through the wringer

      Patagonia makes great products without fail! This pack is by far one of my favorite purchase, so much so I have two. This bag can go with you anywhere, it is durable, light and easy to pack.

      Throw everything you need right in and off you go! Simplicity is great. Only one improvement or nice feature to see is the addition of a key clip, it gives a comforting feeling that my keys will not fall out when fumbling around or forgetting to zip the pouch.

      Great Pack!

      • Familiarity: I've put it through the wringer

      Got this for my wife for a canyoneering trip last weekend. Fits well for a small athletic woman. One large opening makes it easy to stuff. Easy to use cord closure and unflappy flap streamlines loading and unloading rope. Face fabric held up well to the abrasion of canyon walls.

      Go-to for everything

      • Familiarity: I've put it through the wringer

      I've got other packs in this size range, but this one is my go-to for almost any activity. It carries a full load for a day of trad climbing, carries skis fairly well, and compresses down great for dayhikes or other light use. I've even thought about trying to use it for some backpacking. The fabric is fairly durable and the pack as a whole is really light, especially without the framesheet. I also like the top opening, which fits ropes and helmets well, and the simplicity of the design. There are no unnecessary features.
      There are a few things that bug me, though: It could use maybe one more small pocket for a little more organization. It gets annoying to search in that top pocket when I've stuffed ten small items in there. Also, the lack of water bottle pockets or hydration tube gets annoying. It's not too hard to just work around it and keep a water bottle sideways in the top or modify it for a hydration bladder, but it would be better with something to make it easier. Ventilation is also not great, but it's not really much of a problem and this is a mountaineering pack anyway. Keeps your back warm!
      The one other issue I had was that on my pack, the frame did not fit all the way into its sleeve. It was possible to use it that way (or without the frame), but not the best. I took it to Patagonia, and they tried to fit the frame in, compared it to another pack in the store, and asked me if I wanted a refund or exchange. Very easy, great service.

      Great pack

      • Familiarity: I've used it several times

      I am very happy with the quality, versatility and comfort of this pack. I am not a climber, as is the intended use of this pack, but I have found that it works very well for a couple days of camping and hiking. The amount of adjustments that can be made make this a very comfortable pack to wear with a decent amount of weight in it. Even though I have only used it several times, I can tell the quality and durability are going to make this thing last a very long time.

      Perfect for what it is

      • Familiarity: I've used it several times

      I purchased this pack to use for climbing, hiking, overnight backpacking trips, school, and just every day gear hauling, really. For what it is, this pack is absolute perfection. It's minimalist but it holds an insane amount of gear. I'm typically able to fit my 70 meter rope, draws, carabiners, harness, shoes, chalk bag, and helmet in there with ease. I agree with other reviewers that the pack also feels really light and comfortable when you're wearing it. Fear not, long approaches! My only issues with it are not deal breakers but small nit picks: I wish there was a side water bottle strap for my nalgene, and just a few more outside pockets. Other than that, I'm in love with the ascensionist and very happy with the purchase.

      Perfect for what it is

      This baby is money in some areas

        This baby is money in the fact it is super light and a great look. My biggest issue with it is the lack of pockets, it's basically just one big bag without compartments. If that's what you need, get this baby asap!

        Almost perfect

          This is probably my favorite backpack ever - simple, fits like a glove, comfortable for hours, holds a ton of gear, super lightweight, stiff enough to hold rope and has enough side straps that you can lash almost anything to it securely, especially if you add some shock cord between the daisy chains on the back. I've used it for quick overnights, multi pitch and top-rope climbing trips, hiking, backcountry snowshoe trips, and simple weekenders. It has a few drawbacks: no hydration tube hole or sleeve, not super durable (already showing wear after 6 months, and I'm not hard on gear...), and I often wish it had some other entry than top-loading. All in all, though, awesome pack - haven't been able to find better, and may end up with another when I wear this one out. I'm 5'7", 125 lbs female and the S/M is a great fit.

          Questionable durability

          • Familiarity: I've put it through the wringer

          Lots of good things to say about this pack. It's light, innovative design that works for my needs, and carries well. I've taken it out without the suspension to save weight and it's performed well. Where I have to knock this pack is durability. I know it's a light and fragile pack, but I've encountered two issues. The first is that the frame of this pack pulls the fabric very tight and it is easily punctures and spreads. I think the wear came from my ski probe primarily. Second, my skis chewed up the sides of the pack when carrying them A frame after only a few days. The pictures of this pack show someone carrying the exact same skis so I'm thinking this was an intended use, but one that falls short. To their credit, Patagonia repaired both this items free of charge, but this pack simply won't make it through the season. I've switched to the Arcteryx Khamski and have been very very impressed. Check it out.

          Ascensionist in the YK Delta, Alaska

          Speaking of taking this pack EVERYWHERE, I chose this pack to take with me to the YK Delta for a summer of ecology research. We have a lot of equipment to haul and the weather is so unpredictable, you have to bring lots of layers. This pack fits it all and kept my gear very dry in the wet, muddy delta! See my full review of this item below!

          Love the backpack

          • Familiarity: I've put it through the wringer

          I absolutely love these Patagonia Ascensionist Packs. I have the larger 45L and then I picked up the 35L for school/day hikes. I absolutely love this pack it fits super well and is very comfortable and fits everything I need for school with plenty of room left for snacks! I have used it for hikes, climbing, school, everything! Would recommend to anyone looking for an overall great pack.

          Plenty of Space!

          • Familiarity: I've used it several times

          This backpack is the best I've ever owned. I go on many day hikes with the fella and always feel the weight evenly balanced around the pack. Plenty of space for camping and easy organization with separate pouches. Material is heavy duty and has proved it's worth against many rocks and rugged terrain.

          My all purpose, many purpose backpack

          • Familiarity: I've put it through the wringer

          I purchased this backpack for two reasons:

          1. My Avalung Backpack is heavy/not always necessary/has limited space and therefore is not ideal for long ski tours. I purchased this backpack as a really lightweight, higher volume alternative for when the approach is long, but the danger is minimal. I like that it is really compressible: you can cinch it down so it doesn't flop around even if it isn't very full. Also, the padded hip belt and the chest strap suction it to your back when desired so that you can ski or climb free of flopping. Also, the actual buckles work really well, even in the snow or cold, unlike my ski specific backpack's buckles refuse to clasp with what seems like a single snowflake. Also, the gear loops allow you to embark on some more ski-mountaineering types of ventures.

          2. I commute via bike to the gym then directly to work everyday. Consequently, I bring an entire kitchen, wardrobe, and bathroom with me. This backpack can actually hold all that junk, plus my laptop! It solved all my lack of space issues.

          Overall, I would definitely recommend this backpack for activities such as climbing, ice climbing, ski mountaineering, backcountry skiing, and being an office hoarder. I think you'll like it as much as I do.

          All the Stuff in the Pack

          Now when I fill the pack up like this, it seems that the helmet on the top making the bulge would hit your head. I can honestly say that's never happened. I have full mobility when the pack is filled to its capacity, and I have actually fit another set of BD Camalots .1-3 on top of what you see. Seriously an awesome pack!

          All the Stuff in the Pack

          What is the major sizing difference between the large and the L/XL. I've looked around on different sites, and some have just L and other have the L/XL. Are they one and the same?

          I'm trying to decide between this and the Marmot Kompressor Verve 32. I'm going to use it for skiing, climbing, dayhiking, and maybe ultralight backpacking. Are the lack of back ventilation and water bottle pockets an issue?

          Best Answer


          I can't speak to the marmot piece much, but the Ascensionist here is a killer pack for sure. There are definitely other options available if water bottle pockets and back ventilation are important, but I've used this quite a bit for hiking and skiing and it's a great piece.

          What is the difference in dimension of the Small vs Large? I'm 5 feet and about 100 pounds so I know I should go with the small, but the only reason i'm going with the 35L instead of 45L is because I would like the option of taking the bag as a carry on rather than always having to check it. Is the difference between the Small and Large really that vast?

          Hey Danielle,

          The difference between Small and Large is going to be in the torso of the bag. You're spot on that you need a size large.

          For carry-on purposes a 35L would be great, but I've also sneaked by with 45+L before.

          Contact me directly and I'll answer any questions you have.



          I want to use it as a 2 days pack doing hiking at tropical or subtropical weather zones. I just wonder if the water resistant material would survive the nasty incessant raining weather?
          Do I still need an external rain cover if I wanna keep my items dry inside?
          Thanks for answering my question!

          Best Answer


          You might want a full waterproof rain cover. The fabric on the ascensionist does well in the rain considering that it's not fully waterproof, but short of a full dry bag I'm not sure if any pack short of a dry bag would hold up to tropical downpours.

          Does anyone know if this pack fits as a cary on for flying/ would it be durable enough for traveling?

          Best Answer

          If you don't overfill this backpack, it definitely will work as a carry on. I used it as my personal item actually and it 95% fits under the seat in front of you. Then you just put your feet in front of it and act like a perfect little angel with your seat belt nicely buckled so the flight attendant doesn't notice ;). I say, if its durable enough for ice climbing, it should stand up to travels! Good luck!

          Any pictures of this pack carrying skis?

          Best Answer


          There should be a picture up in the details images of a model with a pack and skis mounted A frame style.

          But I will say that carrying skis with this pack could be tough. Not that it is impossible, but it would not be my first choice for a pack to carry skis.

          Im trying to figure out sizing. I found this size guide from Patagonia ( but it appears I'm right in the middle. I'm 5'11" 155lbs, 32" waist and 19" Torso (according to the patagonia size guide). Does anyone have any suggestions on which pack to get?

          Best Answer


          At those dimensions, I'd definitely go for the S/M.

          I am 5'11.5'' (180pounds) with an 18.5" torso and a 32-33'' waist. I went with the S/M because the M/L has a waist best that can only go down to 32" and I wanted to be in the middle of the range as opposed to on the very end.

          Unanswered Question

          Does anyone know if the shoulder straps get longer on the l compared to the medium? The straps are a little to short for my liking on the med

          The pack has a built-in rainfly collar and the material is ripstop nylon, but it doesn't state explicitly that it is waterproof. Is it waterproof, or water-resistant?

          i want a new lightweight pack for day trips with lots of gear but i also need a bag for commuting to and from school, i have tons of bags and only want to buy 1, I'm not worried about how the bag will hold up in the backcountry but is it fine for frontcountry commuting?

          Best Answer


          I think the Ascensionist would be a great pack for you. It is super lightweight, but the fabric is also super durable. And if there are any problems with it Patagonia backs it up with the Iron Clad Guarantee for the life of the pack.

          Yeah, it would be a great bag for you. It can hold a lot of gear and the compression straps allow smaller amounts of gear from flopping around in transit. I can setup the order for you and get you a free return label if you don't like the bag. Email me- and I'll set it up!

          Skis? What are peoples experiences with...

          Skis? What are peoples experiences with carrying skis on this pack? I have tried it out A frame style and my legs hit the tails of my skis a bit--not sure if it is because the bag was not stuffed too much or what. Anyway, I just want to get some info from others.

          Best Answer

          Hey Travis,

          This pack does have a slightly narrow base so like you were thinking packing it out with your more bulky gear at the bottom might help, but really unless you always have your legs spread wide or really swing your hips a lot I can't imagine you hitting your legs often.

          Silly question but have you banded the tips together? If you haven't then give that a try it should widen the base of the A-Frame and get your skis out of the way more.

          Hi Wayne! I did band the tips. I think part of my problem is my Lo5s have flat tails which just puts them in my way a little bit--by other skis have tip and tale rocker so the tails pull away from my legs a little bit. I think I will give it a go just because I love the lid and simplicity so much. My other option is the Khamski 38--so much more expensive! I am sure it is great though, save for the whimpy hip belt. Too many choices out there these days.
