Ski mountaineering combines all the miserable aspects of cold-weather, alpine-style climbing with the adrenaline rush of big mountain skiing. It’s the ultimate punishment tour in the mountains — moving uphill with heavy gear through deep snow and ice — with a perfect payoff when it’s time to go down. If you’ve got the mettle to do it, ski mountaineering is the ticket to the kind of steep couloir and deep powder skiing that others only dream of. We spent this winter testing the best winter mountaineering and ski gear on some of the biggest peaks in Utah and Colorado as we trained for the Power of 4 Ski Mountaineering Race. If you’re looking to start going further in search of deep powder, look no further for the best extreme-condition gear for any winter climbing mission.
