This is a great backpack! Super happy with it. It’s very comfortable and has tonnes of space and pockets. I really like how there’s a built in rain cover (haven’t had to use it yet). I initially thought the water bladder was faulty because it leaked where the straw connected, but it just wasn’t tightened enough! So make sure it’s fully fastened before you head out!

Update: 9/10/25 I wore it for several hours, (in extreme heat and two days in rain) at a WEC race where I walked for miles and had no cover overhead (from sun or rain.) It did not disappoint. The water repellent bag in the zipper pouch on the very bottom is a great idea. Given the packs small size, you can load it up pretty good. The straps and padding and material are all excellent. It's comfortable even with a considerable load. The pack itself is light weight. There's a strap at the chest and one at the waist if you desire to use it. I found the waist one actually helped bear the weight. My original review (before using it) is below: I might come back to give it five stars, but I haven't used it yet. I've never had one of these (of any brand) so I can't compare it to anything else. The main thing, the bladder, is constructed well and rests in an insulated compartment, (as the description says.) I will be wearing/using it a lot at COTA in Austin TX in two weeks and if there's an issue it should show up then. The breathable straps and padding exceeded my expectations. There are other pouches or pockets to store other smaller items. In the largest pocket I can carry my foldable chair. Surprise! With the bladder (two-thirds full) and the chair the entire rig weighs 10 lbs. Not bad for hiking or longer walks. If you are a runner, you won't want to pack so much, certainly not a folding chair. The materials don't look/feel cheap. The attached straps (one at the waist too if you want it) are easily adjustable. I can see where it's lacking anything. We'll see, soon enough.

This is a great Camelbak and doubles as a convenient day pack as well. It has a 2L bladder that secures on the inside once loaded. There is a lot of external storage and plenty of internal storage for a day trip. I searched high and low for a comparable pack and couldn't find anything that could compete with the price. The chest and waist straps secure it to your body to prevent movement while hiking. Highly recommend this item.

Vino con una parte derretida y residuos de plastico fundido; un pequeño detalle desagradable aunque en general la mochila se siente de buena calidad y tamaño
