Compact and weighing well under 3 lbs, the Marmot Lithium 0 Degree sleeping bag is an ideal choice for high-performance cold weather and 4-season backpacking. An array of features and 850+ fill down insulation make the Lithium 0 Degree ready for backcountry adventure at any time of the year.
The Lithium 0 Degree is insulated with certified 850+ fill goose down. Fill power measures the loft or "fluffiness" of down insulation and Marmot goes to great lengths to guarantee the 850+ 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 150% more loft and dries 30% 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 Lithium 0 Degree's insulation is distributed evenly throughout the bag. The Nautilus 3D contoured, ergonomic hood mirrors the design of Marmot's popular outerwear jackets, helps reduce heat loss and keeps your head warm and comfortable. An insulated oversized 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. Marmot's patented Trapezoid Foot Box is wider at the toes and narrower at the heels, providing a more natural fit and improving 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 and storage sack is included.
