Marmot Lithium Sleeping Bag: 0F Down

Marmot designed its Lithium Sleeping Bag to deliver exceptional warmth and comfort, so we can spend restful nights in the alpine. Weighing less than three pounds and filled with light, compressible down, this bag saves weight and space in our pack, while the curved, stretchy baffles make sure their lofty fill doesn't shift, eliminating cold spots.
