Nice backpack certainly for the money. The space is great, tons of useful as well as though out compartments and extremely comfortable shoulder straps. The AirCore straps are absolutely amazing! It does state that it has a laptop compartment however the padding could be better for a laptop. I feel it doesn't offer adequate protections. It is extremely thin but there is at least some padding in the floor however only in the floor, nothing on any of the sides at all! I believe the laptop compartment doubles as the hydration storage as well. Gear loops are nice and this pack could easily work as a school bag, causal/urban work bag, bug out bag (BOB), as well as a daypack. The nylon is 600D so it is a lighter weight daypack that will probably withstand enough for a day trip but I dont believe in the rain or more rugged situations it would be a good choice. I like the water bottle pockets, the waist belt and the compression straps. It is light and built well. However if you are looking for this to store your laptop be aware that the padding could and should be a little better. I dont trust keeping my macbook pro in there...especially considering the price tag on a new macbook pro. With a few short comings this bag is still absolutely excellent!!! I love it, just wish the laptop compartment was better.
