It would be great if there were a steel structure.

Great Commuter Backpack
on July 24, 2026
Posted by: Twenty1PilotFan
from Chicago
I have had this for about 5 weeks now. I love the look of it and storage space. It is a little bit difficult to use all the features but overall it is the most comfortable day to day commuter pack I have ever had.
I would recommend this to a friend!

Great 25l pack, but strange bladder routing
on July 23, 2026
Posted by: Paul Bakker
I have the 25l version and use it primarily for day hikes. There is a lot to like.
- It's very comfortable to wear
- The side pockets are very deep and work great for 1.5l water bottles
- The open/close mechanism of the "flap" is very easy to use (once you figure it out)
- The flap is a great place to stow jackets etc. that you need easy access to
- The (phone) pocket on the front of the shoulder strap is great
- Attachment points for straps

The one strange miss is the routing for the water bladder. I have tried several bladders, and all of them are designed to route the hose upwards. The bag is designed to route the hose downwards, which doesn't work with any of the bladders I have. This setup seems really unnecessary complicated, and I end up just not using the hose routing. It still works fine with a bladder, but it's still a strange miss in the design.

Incredible versatility
on July 21, 2026
Posted by: Rick

The versatility of the 45L is amazing! There are so many ways to utilize the pockets and spaces. I’m still trying different ways to store all my camera gear and accessories, tripod, water bottle, etc. The frame and the way the hip belt fits makes the pack very stable and unlike other packs I’ve used. The dual sternum straps are a great idea, however I’m still fiddling around to get the hook attached into the correct loop. Hopefully that will get easier with use. A big factor for me was the materials used and the pack being PFAS free!.
I would recommend this to a friend!

Different than the 45L Travel or 25L Outdoor packs
on July 16, 2026
Posted by: jw
from Los Angeles
I like how this bag distributes weight. The straps are better on this one than on the 45L travel backpack making it more comfortable to wear for long periods of time. It's also surprisingly different than the 25L outdoor backpack - besides being larger, it has more little pockets and places to store things.
I would recommend this to a friend!

Sleak and Functional

The outdoor backpack suited my needs perfectly on my recent camping trip. Its rugged and sleak. I added the hydration pack and it took the bag to the next level when hiking. Love it!

Great bag, a couple misses.
on July 15, 2026
Posted by: Fendy
from San Mateo, CA
So far I am pretty happy with this bag. I’ve taken it on one trip and several hikes. As others have noted, the water bladder compartment lacks a solid way to hold the bladder in place, but I’m finding some work arounds. I find the rest of the compartments to be well designed and versatile. The exterior TPU coating is a little delicate, I already have circle mark on the exterior for putting my watch in there on a brief outing. So the quick wear on that exterior coating and the bladder are the main reason to ding a star. I got it at a decent deal - the peak design “don’t tell Dave” sale and my Amex offer - so overall I am pretty happy. For me it will be a travel backpack that I can turn into a hiking pack when I get there. We’ll see how it holds up on an upcoming Norway trip.
I would recommend this to a friend!

Works for EDC, 45L
on July 15, 2026
Posted by: jkim
I bought the 45L for EDC. While it is heavier than my case logic backpack, the hip straps feel great and take most of the load, quick access pouch is easy to access, and I put my quick access items in the pouches so I usually open the main compartment once or twice a day.
