When your focus is on packing light and staying warm, the minimalist Marmot Lithium 0 is your sleeping bag. It keeps you comfortable on extra chilly days with its premium, water-resistant goose down.


  • Certified 800-fill-power goose down features ExpeDRY for quicker drying
  • Main zipper with antisnag slider and fold-down second zipper provide added ventilation and easy access
  • Anatomically designed footbox with wraparound construction increases warmth
  • Smooth, curved baffles reduce down shifting
  • ISO tested for reliable temperature rating
  • Stuff sack and storage sack included


Temperature ratings are intended as a guideline to help you compare products, rather than a guarantee of warmth, since many different factors contribute to your comfort while you sleep. Backpacking bags are typically rated for temperature according to an independent testing protocol—currently International Organization for Standardization (ISO) 23537, though some older items followed European Norm (EN) 13537. Testing is based on a person wearing one base layer and a pair of socks, sleeping on an insulated surface with a minimum R-value of 5.38.

Each bag then gets 2 ratings: the Comfort rating is the lowest temperature at which the bag will keep the average "cold sleeper" comfortable, and the Lower Limit rating is the lowest temperature at which the bag will keep the average "warm sleeper" comfortable. Some brands determine their own temperature rating by aligning to the Comfort rating for women’s bags, to the Lower Limit rating for men’s bags, or somewhere in the middle for nongendered bags.
