The Marmot Manta is the consummate all-arounder - at 10 it withstands even winter outings, and with 650 fill down plus, Marmot's most advanced design, it excels in any outdoor, overnight activity.
Designed to keep toes warm with a double layer of insulation in the foot space, the Marmot Manta +10 sleeping bag offers warm, 650-fill down for cold-weather outings. The Marmot Manta +10 sleeping bag features a tough nylon shell with a Durable Water Repellent finish and 650-fill-power goose down insulation. Trapezoidal footbox allows down to loft fully around your feet for optimum warmth and comfort, and double-layer of insulation enhances warmth. 6-baffle hood envelops your head in warmth, and the face muff allows hood to be cinched snug without digging into your face. Locking, 2-way zipper prevents bag from inadvertently opening during the night; heat bump draft tube backing the zipper seals out the cold and reflects heat back to your body. Zipper guards prevent material from snagging in zipper; reversible zipper pulls work easily inside or outside of the bag. Baffles are made with stretch tricot, providing strength and long-lasting wear; vertical side baffles keep down in place. Ground-level side seams eliminate cold air leaks. No more midnight drawcord fumbling-smooth, flat upper cord and hard, round lower cord make hood and collar adjustments easy. Stash pocket holds nighttime essentials within easy reach and tucks away along the drawcord. The Marmot Manta +10 sleeping bag includes a stuff sack and large storage bag. Closeout.
