Comfort in the coldest places.
Marmot designed its Lithium 0-Degree Down Sleeping bag to deliver exceptional warmth and comfort, so you can spend restful nights in the alpine. The Lithium is part of Marmot's ultralight lineup, weighing just over two pounds, and 800-fill down gives it the compressibility needed to be a viable option during those more gear-intensive backcountry missions where every inch of pack space must be carefully considered.
The Lithium features newly redesigned baffle construction that uses a curved shape to help keep the water-resistant 800-fill down from wandering throughout the night. The foot box is anatomically shaped to give your toes some extra wiggle room and has a wrap-around construction to limit the amount of areas where heat can be lost as you sleep. Even though the down is coated with a Down Defender water-resistant coating, Marmot also used treated both the lining and Pertex Microlight face of the bag with a DWR finish for extra protection against moisture. Pertex Microlight fabric is also superlight and highly breathable, so it saves ounces and makes sure you don't sweat and wake up frozen in the middle of night.
