The Marmot Plasma 40 Sleeping Bag uses heaps of advancements in fabrics, insulations, and designs that add up to the most evolved sleeping system on Earth. Marmot continues to pioneer in Sleeping Bag technology with major developments. The lightest weight bag in the 875-fill power down Plasma Series, this ultra light, ultra packable sleeping bag is tailor made for the fast and light route. The new Plasma 40 sleeping bag is the most technologically advanced bags on the market. The new design features combine to make the warmest, lightest most functional bag possible. Rated to 40°F and weighing in at less than two pounds, the bag contains high-quality 875+ Fill Power water resistant goose down to provide superior insulation for fewer ounces and extra protein in wet environments. Pertex Quantum® face fabric is lightweight, water-repellent, and breathable, yet dense enough to resist rips and punctures. Marmot’s Flow Gate Construction allows body heat to flow evenly while keeping down in position around your body. The Marmot Plasma 40 Sleeping Bag also features an internal baffle system, called Insotect Flow, which keeps the down from sliding down the bag and improves heat transfer. Vertical Baffles optimize thermal performance and significantly reduces weight compared to the “classic” baffle construction. Additional features of the Plasma 40 include a wrap around foot box construction, a full length zipper, insulated draft tube, insulated collar, Velcro free face muff, two hang loops, and two way zippers. Marmot's 40-degree Plasma breaks the two-pound mark—the average 40-degree down bag weighs two and a half to three pounds. This is a major leap forward in sleeping bag technology. And we all know Marmot know how to do it right. With over a year and a half in the making, the ultra comfortable Marmot Plasma 40 Sleeping Bag is the warmest, lightest and most compressible sleeping bag ever!
