I like this versatile backpack not only for my hikes in nature but also when I'm travelling on a plane. When I travel, I take out the hydration reservoir and my 13" computer fits perfectly inside, and there's another zip up pocket for my wallet, phone, floss, gum, passport, and other miscellaneous stuff. On the plane, It fits nicely under the seat in front of me giving me enough leg room.

I remove the hydration bladder and use the backpack on small excursions. Just the right size for little items.

This pack is nice and it does the job, but there were a few items I would have liked for it to have. First off, a small internal zippered pocket on the inside of the main compartment for smaller items like keys, ear phones, etc. As it is you just pile everything into the pack and the small stuff ends up on the bottom buried under whatever else you have packed. Next I would have also preferred the hydration pack to come with quick disconnect fittings rather than threaded ones which can back out and leak. Lastly the hydration hose is a bit too long in length, which then magnifies the issue of the pack not having a clip on the shoulder strap to secure the hose and mouthpiece. As it is, the hose is just flailing in the wind bouncing around while bicycling / skiing.

Love this pack as a day pack / hydration pack, and even for longer trips. It can really hold an incredible amount, and is super durable.

Typical backpacks for adults are large and can be hot when carrying them on the back due to their size. This backpack is smaller, lighter, and just the right size for day use or shorter trips. It's designed very well with durable water resistant material and two main pockets with heavy duty zippers that can be locked with mini locks and a small open front pocket for keys or a phone. It includes a hydration bag. There are numerous outer pockets, vented padding, and two support straps on each side to keep the contents secured and close to the body. I definitely recommend this backpack!!
