Pack you can fit in your pocket

  • Familiarity: I've put it through the wringer

I would be the last to claim that this pack will have incredible durability, but life is full of trade-offs. With this pack you get an amazingly light day/summit pack, so light that I often pack it inside of a bigger back on longer missions.

One feature that might not stand out at first is the removable back pad, which can be used as a seat/bivy pad, whether inside the pack or taken out.

Great addition!

  • Familiarity: I've put it through the wringer

This pack is very versatile.

Extremely light weight and absolutely no structure. Takes a little getting used to but now I use it all the time. Mostly day hikes / day climbs. Love that there are external tool loops and that my water bladder fits into the compartment where the foam back support is.

I wouldn't load it up too heavy though. I've gotten it to a point where the weight wasn't ideal for the little amount of support it provides.

Folds right down into it's own top pocket so it's great to throw into a larger overnight pack for a summit day or day hike while out in the backcountry.

Light and versitile

  • Familiarity: I've used it several times

I couldn't believe how light this pack is. While it might not have all the bells and whistles, it is great little versatile bag.

The material is top notch and seems like it would hold up to light rain(haven't used it in the rain yet, however). The top pocket's zipper is taped which is a nice touch. The pack includes two ice ax attachments which is great to see on a small lightweight day pack. I really like what they did with the exterior elasticized shock cord lashing system. This will allow you to attach a wide range of items to your pack. I like the design of this so I have to option to toss my skis on the pack if I run into a short climbing pitch or can't skin for some reason. The shock cord also allows you to compress the bag down really well. The padding on the back can be removed, allowing you to use it as a stuff sack for your sleeping bag or other gear. The hip strap is very minimalist. Don't expect to put too much weight in the pack and have it comfortable. Others have said that there is a hydration compartment... I don't think that is what it was intended for but I suppose one could use the back padding compartment for that purpose. One downside to the pack is that the lid on the top of the pack cannot be removed. This would be a nice option to have and would increase the versatility that much more. Another improvement would be adding a small hole for a hydration system hose so one doesn't have to run it through the top of the pack, which makes it a little messy.

All in all a great pack though and one which can be used for a variety of situations. Would definitely recommend this product to anyone looking for a lightweight, multipurpose, technical pack.

Great pack. simple design.

  • Familiarity: I've used it several times

I use this daily be it outdoors or around town, even as a computer bag. It sheds water well. I was nervous that the straps had no padding, but it's not an issue. As usual, Arc'teryx delivers in design and durability. I used it as a summit pack in the Tetons and it performed extremely well.

Solid Fun Lightweight Pack

  • Gender: Male
  • Familiarity: I've put it through the wringer

The Rei Flash and Marmot Kompressor packs are both in this lightweight light and fast category, but the Arcteryx Cierzo 25 feels more durable and has a better compression system. The Cierzo 25 also sheds water like a duck, and I enjoy this a lot, but I still use a dry sack for gear that needs to dry. The Cierzo 25 also has a hydration sleeve when the thin foam back pad is removed from it's internal pocket. The backpack can also expand from 1600+ to 1900+ cubic inches. That's plenty of space for a day trip. The pack's harness and belt are thin, but they deliver serious ergonomic comfort. The zippered compartment on the lid is also very large and has waterproof zippers. Also, the one size fits all backpack design eliminates sizing issues and this is a nice factor. For durability, workmanship, material and design I've given this backpack five well-deserved stars.

Hi, I'd like to know according to your own experience, what's the maximum weight you suggest this pack carry while we want to stay comfortable using it for a trek? I usually carry 7-8lbs for a day's hiking that lasts 7-8hours, I wonder if this pack can work without bringing pain to my shoulders in this situation? Thanks?

Responded on

That weight would be very cool! If you're carrying a hydra-pak or other h2o bladder, it can rest in the sleeve for the foam pad. Pack soft stuff low, slightly heavier high. If you plan to carry a very thin sleeping/yoga pad you can make it a tube shape and pack you stuff inside to add shape if you need to. Hope this helps.

thanks for the info on removing the foam pad and using the sleeve for a bladder. I was wondering about that!! I want to be able to use this with a 3L bladder.

Agree that 7-8lbs would be no problem at all for this pack.

Feedback based on 2013 version

  • Familiarity: I've used it once or twice and have initial impressions

There are very few differences between this and the 2013 version and after looking at the new version I thought I'd give some feedback that might help people out.

This is an extremely lightweight and relatively versatile pack. I can easily fit my osprey hydraform (old model) bladder in the "framesheet" sleeve (I take the foam out now-a-days to cut weight and because the bladder I have provides plenty of nice curvature and padding for my back). Then I can stuff it full of snacks, food, and clothes. I can actually even fit a bear canister (full of food) (or a tent) AND, a sleeping pad, sleeping bag, and clothes in it - though I've yet to try an overnight like this. This pack comes with me shoved in my backpacking bag when we're using a tentsite as a base camp and is my go-to pack for day hikes.

Prior to this pack, every pack I owned offered tons of support but I realized with this that I don't need support in a small pack.

The material is great and hasn't worn out on me yet. The top compartment/lid is huge and fits tons of stuff (including the entire pack obviously!). The lightweight cords on the outside cinch down nicely to provide structural integrity with smaller loads or provide the option to put more gear on the outside of the pack. The ice axe/trekking pole loops are my favorite on any pack because they're incredibly simple to use. Finally, I love that you have to manually adjust the chest strap to the slot that you want because this means you don't have to worry about it slipping up and down.

I highly recommend this pack based on the similar older version and my brief experience with the newer version!

Is this pack hydration compatible? Or is...

Is this pack hydration compatible? Or is there a way to hang up a bladder like in the sleeve for the frame sheet or something?

Best Answer Responded on

This pack has no system set up for housing a hydration bladder.

Responded on

I find that the slot for the frame sheet is tight enough that it gives support to a water bladder - but I do use the osprey bladder system which has some rigidity to it. I haven't had any issues with it sliding or causing back issues (actually the osprey bladder gives extra support to the pack!). I was hung up on the lack of hydration compatibility but I gave the older model a shot anyway and I use this pack for everything; seriously it comes with me every single day. So even though it's not technically compatible I think you can make it work - or at least I do!
