The Marmot Mad River 40° Short Sleeping Bag is a packable down mummy bag built for backpackers who want a reliable night's sleep on the trail. Filled with RDS-certified 650-fill-power duck down treated with ExpeDry™, it lofts up tall yet packs down small, and the chemical-free technology helps the down dry quickly and retain loft in damp, humid conditions. The short length fits sleepers up to 5 ft 6 in, making it a gender-free option for smaller frames.

Its full-length left-side two-way zipper with an anti-snag slider and a secondary right-side zipper let you vent or fold down the bag for blanket-like coverage as conditions change. The anatomically designed footbox with wrap-around construction gives your feet room to move, while the draft collar seals in warmth. An internal stash pocket keeps small valuables like a headlamp or contact lenses secure, and the included storage and compression sacks make it easy to pack down and head out.
