Purchase thru Marmot

The Marmot Hydrogen 30° Down Sleeping Bag is an ultralight backpacking bag built for thru-hikers and fast-and-light mountain travelers who count every ounce. It is insulated with RDS-certified 800-fill-power goose down treated with quick-dry ExpeDRY, and its smooth curved baffles keep the down from shifting so warmth stays consistent across the bag. An anatomically designed footbox with wrap-around construction adds warmth at the feet, while the anti-snag main zipper and fold-down second zipper provide ventilation and easy entry and exit.

ISO-tested for reliable temperature and comfort ratings, the standard length fits sleepers up to 6'0", and the bag comes with both a stuff sack and a storage sack. It is machine washable cold on a gentle cycle with liquid detergent and should be tumble dried low.
