I just got finished using this to backpack in the alps for 3 weeks and overall this bag is really great. It is highly adjustable, holds a lot, and the set-up of the many pockets make it easy to organize your gear without compromising your ability to carry bulky items. A few small concerns: the side water-bottle pockets are made of an elastic material that I'm not sure will wear well, there is no pocket on the hip belt for snacks, camera, whatever, and I agree with the previous review that the frame can make some weird squeaky noises depending on how you have it loaded and how the straps are tightened. Also, the frame is insane, it seems like it would be enough for a MUCH larger pack. That lets you carry some pretty serious weight comfortably with this pack, though, and the only down-side is it's a little on the heavy side. Overall, a GREAT buy. It comes with a rain cover that stores in it's own little pocket in the bottom of the pack too, which makes it easy to access while on the trail.
