The Marmot Mad River Down 0° Long Sleeping Bag is a packable down mummy bag built for the backpacking traditionalist who wants a solid night's sleep after a long day on the trail. Its RDS-certified 650-fill-power goose down packs small yet lofts up tall, and chemical-free ExpeDry™ technology permanently helps the down dry quickly and retain loft when sweat, humidity, and condensation set in.

The gender-free long length fits sleepers up to 6'6", while the 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. An anatomically designed footbox with wrap-around construction keeps feet warm and roomy, a draft collar seals in heat, and an internal stash pocket secures a headlamp or contact lenses. The included storage sack and compression sack let you pack down tight from day one.
