• Never Used or Taken Out of Bag
• Water-resistant down insulation ensures all-condition performance: The bag utilizes certified 800+ fill power goose down with ExpeDRY to grant an excellent warmth-to-weight ratio with weather-resistance to keep on insulating even when damp or wet. Recycled Pertex Quantum shell fabric increases weather-resistance.
• Thermally efficient design features: The bag's mummy shape helps to reduce weight and eliminate cold spots and curved baffles reduce down shifting to further ensure consistent warmth. An anatomically designed footbox increases warmth in a common area of heat loss.
• Unique zipper configuration adds versatility: The main zipper running down the side of the bag has a smooth-gliding anti-snag slider and a second zipper segment on the other side allows the front of the bag to fold down for easier access and for venting on warmer nights.
• ISO tested to confirm the bag's temperature rating: Marmot took all the necessary steps to test the Lithium so backpackers can be confident in its 0 degree Fahrenheit temperature rating.
