Maybe it's the fact that I haven't had a fully functional backpack for years, or maybe it's the ability to hold such a copious amount of material, but this backpack is very useful!!!
I'm a student so I'm using it to lug books around and notes in the main pocket, my gym clothes in the second one, and various tidbits at the smallest pocket. I also use the two small pouches to hold my cards, some medical items, and other stuff.

I'd highly recommend this backpack!
