This is a great pack. The reActiv suspension/swing arm do exactly what they say...they move with you. Used it climbing in the Tetons...hiking up, scambling to base of climb, hiking down...it moved with me, carried the load great and didnt give me any sore areas on my hips. Doesnt have a bunch of stuff you dont need and the rope strape under the top pocket is a nice touch to hold a rope in place. I wasnt sure if I would like dealing with the roll top closer but I like it, especailly if you take the top pocket off.
