This is the best pack that I have owned, ever. It is somewhat purpose built as a mountaineering pack, but can easily be modified to work extremely well as a Ski or ski mountaineering pack. The pack is about 4000 cubic inches (not counting the storm/bivy skirt) fully expanded. It compresses to ~1800 cubic inches using an ingenious and simple zip compression system. The pack has been updated a few times since inception, and the newest versions are supposed to be lighter, stronger and more comfortable. My older model is holding up fine after 7 years of heavy use, and if I ever manage to wear it out, I will surely buy a new one.
