The Marmot Atom 40 Sleeping Bag is the “it” bag for alpinists and spur-of-the-moment road travelers. Hunter S. Thompson totally would have had this bad boy in his trunk. This 850+ fill goose down Marmot sleeping bag has 8 ounces of high quality down hand stuffed into sewn-threw baffles, which helps keep the weight down to 1 pound 5.52 ounces. This warm weather sleeping bag has six baffles around the head for optimal down control and a close fit, along with a conveniently positioned hood cord for easy access. No cold ears with this bag. Along with the overstuffed, insulated draft tube and Velcro-free face muff you’ll find on most Marmot sleeping bags, the Atom 40 also has zipper guards to keep the zipper from eating fabric, a DWR coating and includes both a stuff and storage sack. Marmot started as a sleeping bag company, so they totes know how to kill it when it comes to a comfortable, lightweight down bag.
