JanSport Klamath 75

I really have no big complaints about this bag. It was very reasonable in price, placement of the compartments makes sense, and JanSport has a lifetime warranty!

This bag is very comfortable on long trips. It's very roomy and when it's all packed correctly, it's nice and balanced. The straps are nice and sturdy, and the zippers work well and are smooth (they don't get stuck much at all).

Compartment locations make sense, and everything is pretty easy to access. I like the big pocket on the front of the pack. It holds some pretty large stuff. 

At first, the material seems a little thin, but it holds up, and it makes the pack lighter. It also comes with JanSport's lifetime warranty, which makes the price seem even better.

Only complaint would be a small one, that a waist belt compartment would be nice.

I haven't used it in wet conditions yet, so I can't comment on its water resistance.
