I bought this for climbing pack and or summit pack. I wanted something i could take on a multipitch climb and walk off a different route. The best park of the pack is the compression staps at the top and bottom so the bag can be compressed for size and keeping the weight tight against your body. The belt is light weight and provides good support verces a single 1" stap belt but is not bulky. The pack has spots for ice axes for treking poles so you can use it for anything. The outside pocket is great for my rain jacket or anything else i need to get to fast. The pack comes with a couple extra pockets which is great for organizing a few items you need to locate. The pack fits me great i am 170 - 5'9" athletic build. It also fits my girlfriend better than all my other packs as she is 110 lbs which is perfect if she needs one to borrow for one of my planned aventures. I use the pack as my everyday pack to bring things to and from work i like it so much. I bought it at moosejaw!
