This pack is perfect for alpine style ascents. It's very lightweight, simple, and durable. It's got plenty of room. The compression strap system is excellent. It doesn't have a seperate sleeping bag compartment, which I like, but some people might not. The top lid detaches easily so it can be used as a stuff sack. The suspension is geared for fast and light style approaches. It doesn't carry over 55-60lbs very comfortably, but if your carrying loads that big you're probably using a different pack anyways. (It should be noted that the picture displayed is last year's model)
