Marmot Helium 15° Sleeping Bag

Climbers need a warm sleeping bag, whether at basecamp or for an unexpected bivvy. On those potentially “epic” climbs, our alpine-oriented testers carry the 2 lb., 2.7 oz. Marmot Helium 15° Sleeping Bag. What makes this bag stand out is that it’s insulated with light, warm, compressible, 800-fill ExpeDRY down. Developed by ALLIED Feather + Down and FUZE Technologies, ExpeDRY down is a chemical-free solution that maintains the warmth and compressibility of down while performing better in wet, humid conditions. ExpeDRY bonds FUZE Technologies’ non-ionic gold particles to ALLIED’s down insulation to increase the evaporation rate of water at a molecular level. The sleeping bag can be used as a bivvy sack when you’re going tentless. Plus, there’s a nifty inside pocket for your phone and glasses.
