I can stuff a climbing rope, static rope, slings, biners, harness, and crampons in this pack and still have room for extra layers, my hydration pouch, lunch and snacks. The pack sets the weight on my waist comfortably, even if the shoulder straps are a bit narrow for my frame. The construction is SOLID, more so than any other pack I own. It's a great pack for a day of climbing, but lacks the compartments to make it a well organized weekend pack. I do use it for overnights, but I travel light and sleep in a hammock.
