This is an EXCELLENT product, no doubt, plenty of room, very good design, I can't find something wrong on it
It fits you in the back very well, the fabric is very resistant, is not so heavy. The water reservoir is not the normal one, it's a new design (maybe) that seems to me more durable. The straps in the hip and the chest helps you to keep it in your body with minimun of movement during you are walking
A lot of divisions, inside straps, compartments and mesh pockets that helps you to keep your stuff straight
I bought it in Desert Camo Color and this color can comes dirty very easy, if you chose to use it for backpacking arround the world in Planes and Buses like I did it Don't make the same mistake and chose the black or olive drab.
