Despite weighing less than 3 pounds, the Marmot Lithium 0 Degree sleeping bag is an ideal choice for cold weather backpacking. An array of features and 800+ fill water-resistant down insulation equip the bag for backcountry adventure.
The Lithium 0 Degree is insulated with certified 800+ fill goose down. Fill power measures the loft or "fluffiness" of down insulation and Marmot goes to great lengths to guarantee the 800+ certification with a battery of in-house and external verifications. Renowned for their efficiency in retaining heat and compressible properties, the feathers and fibers of down have an incredibly soft, comfortable feel and, despite advances in synthetic materials, continue to provide the best warmth-to-weight ratio of any insulation available. The one weakness of down insulation is that it loses much of its ability to maintain warmth when it gets wet; this is less of a problem in the Lithium 0 Degree, though, since the down in this bag is protected with Marmot’s Down Defender water repellent treatment that allows the down to stay drier 10 times longer than untreated down in damp conditions. Down Defender down also maintains significantly more loft and dries faster than untreated down.
Despite its lightweight construction, the Lithium 0 Degree makes no sacrifice with regards to performance and features. Eliminating cold spots and providing comfort, sewn-through baffles ensure that the insulation is distributed evenly throughout the bag. The contoured, ergonomic hood helps reduce heat loss and keeps your head warm and comfortable. An insulated draft tube sewn behind the full-length zipper keeps cold air from reaching the inside of the sleeping bag and zipper guards help to avoid irritating and damaging snags. A “fold down” second zipper enables you to vent the bag when needed and also makes it easier to get in and out of the bag. An anatomically-designed footbox provides a more natural fit and improves warmth and comfort.
Filled and finished in the USA (Rohnert Park, CA), the Marmot Lithium 0 Degree sleeping bag is available in Regular (fits up to 6' 0") and Long (fits up to 6' 6") lengths. A stuff sack and storage sack are included.
