Purchase thru Marmot

The Marmot Mad River is a packable down mummy bag built for backpackers who want a solid night's sleep after a long day on the trail. Its RDS-certified 650-fill-power duck down packs down small yet lofts up tall, and chemical-free ExpeDry™ technology permanently helps the down dry quickly and hold its loft when sweat, humidity, and condensation set in.

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