with this pack, its hard to even know where to begin in praising it. It is such a simple pack, yet as I have used it more and more over the years, I find new things that make it interesting and even more resourceful. I love the removable top pocket and have actually used it much more than I ever thought I would. Added clips on the frame make it compress after you unload some at base camp and set out for more. trek pole holders, axe loops, breathable back piece, and molded hip straps make it feel as if you arent even wearing everything. I hate going on an overnighter knowing that I ought not to take it as it is more designed for extended trips, I just dont enjoy being out without it. Even the little things like the two water bottle holders on the sides and the whistle on the chest clip are the small ammenities that make this bag wonderful. Not to mention how durable it is. Mine fell down a snowfield and came out alive and unscathed. If trying to decide on a bag, dont forget ospreys all mighty guarantee.
