This pack is fantastic. I've used it to ski Tahoe all season and it hasnt let me down once. My only issue is that since im quite a large person ( 6'5" 210lb) it doesnt exactly fit perfectly, but thats completely expected. I have no complaints, it will fit a few cans of beer, an extra goggle lens, a jacket, and 2 water bottles well (providing you stuff the jacket in well). It has been fantastic in the snow as well. Not a single drop of water has entered the pack. Durable as well. Stands up to trees and branches and rocks quite well. Good buy, good pack. Solidified my love of Black Diamond gear.
