Perfect for hiking, backpacking, camping, or even as a work bag. Holds a lot, has many useful pockets, and is very cheap for such good quality. The straps on the bottom of the bag are very useful, and it is very easy to carry, the secondary support straps for the waist are very useful. Very sturdy and waterproof cover works well. Perfect product, no complaints. ... show more

    • Would buy again! Great pack!

Great pack! We had initially purchased another bag for this years summer camp, but it was too small to fit our binder! This pack fit it perfectly, as well as all of our other supplies. We carry a lot with us at camp, and there were more pockets and sections of this pack than we could fill! A good problem to have! The two chest straps were perfect, and make the backpack much easier and more comfortable for long days of wear. It’s also very light without anything in it! Our only issue was that the zippers got stuck/broken towards the end of our season. This was after weeks of rough wear, but worth noting. Thankfully, there were double zippers on this pouch, so we were in luck! ... show more

    • Great Outdoorsy Backpack for a Good Price
Size: Large Color: Black
The backpack is great quality. Zippers area good strength, their are so many compartments; I feel like I'm still finding more. The waterproof nylon material is very effective. I love how it looks, not too bulky, but not tiny either. All the straps on it makes it super secure on your back.

    • Good quality but doesn’t fit my build
Size: Large Color: Blue
I am 5’ 11” and this pack claims to be a large but is too small. If I wear it where the straps are comfortable, the hip belt is around my belly. If I adjust so that it sits properly on my hips, the helper straps are down behind my shoulders. My wife is 5’3” and the pack is too large for her. Ideal size must be somewhere in between us Pros are that it has lots of pockets for organization. I particularly love the pockets in the hip belt. I keep snacks in one and my battery backup in the other. Currently set up with a 3L hydration bladder and there’s plenty of room. Zippers and material have held up nicely for multiple day hikes Used the rain cover on one rainy hike and my gear stayed dry Overall great quality for the price, just wish it fit better My plan is to purchase an external frame and attach this pack to it ... show more

This is a huge backpack. I got it for a trek in the Himalayas - however it was slightly larger than what I needed. There is one zipper compartment that holds all this space. There is a smaller zip on the front that is great for putting documents and holding smaller stuff. The side pockets are big but the design is crazy - the zipper opens too far down and so you risk dropping stuff when opening it. I like the mesh for 2 water bottles but again built for a large size one and no way to fasten it so the bottle can fall out. The fasteners for filing poles worked great. The cushioning on back is excellent. It would be nice to have a place to lock the waist belt - thinking if I had to check-in the bag. Overall worked but many improvements can be made. ... show more

    • Comfortable backpack for a 4‘10“ woman
Size: Large Color: Blue
I just got this so I need to walk around with it outside for a bit but initial indications are that this is a hit! I am 4‘10“ and I find that it sits on my hips effectively so that weight transfers there from my shoulders. I am probably at the lower limit of what this pack will fit, I’m about 114 pounds. But if I tighten all the straps all the way it seems like a perfect fit for me. I tried another big name brand and I wanted to take it off the minute and I put it on. Granted that was a frame pack. But this one felt right from the beginning. Lots of useful pockets and a well-thought-out design. ... show more
