I've only used this pack once so far, but it worked out very well. Brought the pack on a day in the back country and it fit a 2L camelback, extra layers, avy gear, snacks, and skins. The straps for the waist belt are extremely long and I trimmed mine much shorter. I really like the hip belt pockets for storing a camera and energy bar. The separate pocket with spaces for probe and shovel is a convenient way to organize avy gear. The strap system is pretty complicated and can sometimes get in the way when trying to get items out of the bottom of the pack.
