Purchase thru Marmot

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

The long, gender-free cut fits sleepers up to 6'6", and the 100% recycled shell and lining keep the build responsible. A full-length left-side two-way zipper with an anti-snag slider and a short right-side zipper let you dial in ventilation, while the anatomically shaped footbox, draft collar, and internal stash pocket round out the details. A storage sack and compression sack are included.
