Marmot Helium 15° Down Sleeping Bag Long

The Marmot Helium 15° Sleeping Bag is an ultralight backpacking bag built for long-distance trips where every ounce counts. Its RDS-certified 800-fill-power goose down insulation uses a quick-dry ExpeDRY treatment, and the ISO-tested 15°F rating keeps warmth reliable in cold conditions.

The long length fits sleepers up to 6'6", while the anatomically designed footbox with wrap-around construction and smooth curved baffles hold warmth in place and keep down from shifting. An anti-snag main zipper and a fold-down second zipper add ventilation and easy access, and the bag comes with both a stuff sack and a storage sack.
