The last pack I'll ever have to buy!!
I bought it primarily as a book bag for school. It fits my 15" HP notebook and keeps it secure along with books. Organization pocket is handy for my calculator, pens, keys and whatever else I seem to stash in it. It holds a lot of things while maintaining a slim look. I also use it as a daypack, It has a hydration hanger and opening. I don't think they mention that in the features. I took the bladder out of my Camelback and presto! I've gone thru a bunch of packs, but like I said this is the last pack I'll ever had to buy. I do have my eye on the Heckler though, but that's just 'cause I like the camo scheme.
