For big alpine missions where it’s you, a partner, and thousands of feet to climb, the Phantom™ Alpine provides high-lofting warmth that takes the sting out of on-mountain bivies—planned or unplanned. It cuts your load weight so you can do more climbing and less hauling. Better yet, while you stay warm, stay tied in. Dual side zippers allow openings for your harness so you can securely sleep, boil water, and rack gear.
