Offering luxurious ultralight warmth, the Marmot Plasma 40 Sleeping Bag uses water-resistant buttery smooth Pertex Quantum fabric and is filled with gourmet 900+ fill power down -- some of the highest quality down you'll find. Weighing just over 1 pound, this Plasma sleeping bag is rated to 40F for 3 seasons of comfort in the backcountry. Perfect for backpacking, thru-hiking and fast-and-light adventures, this Marmot down sleeping bag has an Insotect Flow™ Vertical Baffle System to reduce down shift and give you warmth where you need it most, and it stuffs into a tiny bundle to save space in your pack. The wrap-around footbox has a trapezoid shape for a natural foot position while you sleep and the insulated hood and collar have a Velcro-free face muff to keep rough things from irritating your cheek and chin. Keep your base pack weight low and sleep soundly in the backcountry in the Marmot Plasma 40 Bag.
