The Marmot Mad River Down 40° Short Sleeping Bag is a packable mummy bag built for backpackers who want a reliable night's sleep on the trail. Its RDS-certified 650-fill-power duck down lofts up tall while packing down small, and the chemical-free ExpeDry™ treatment helps the down dry quickly and retain loft when sweat, humidity, and condensation set in.

The gender-free short length fits sleepers up to 5'6", and the 100% recycled shell and lining fabrics keep the bag light on the planet. A full-length left-side two-way zipper with an anti-snag slider and a short right-side zipper give you precision ventilation and blanket-like coverage, while the anatomically designed footbox, draft collar, and internal stash pocket round out the details. The included storage sack and compression sack let you cinch the bag down and head out.
