My father uses this pack, but I have no shame in borrowing it either. This pack can fit a very large range of bodies. It's very adjustable and much easier to do than say, my Osprey Aether 70 (awesome pack). I would say that this pack is just as good as my Aether 70 but for a lot cheaper. I like the hip-zip-pocket on this bag too.
However, one of the straps did rip off on the first trip. I'm not sure if it was Dueter's fault here or mine, but I'm not too upset.
