This unisex sleeping bag features a 3-in-1 sleeping system with three interchangeable layers to configure it for 5, 20 or 40 degrees F temps. For mild nights of 40°F or warmer, use the lightweight, synthetic outer layer on its own. Removable mid layer has lightweight, compressible 800-fill-power goose down for warmth down to 20°F. Combine the outer and mid layer for a super-warm, 5°F bag that's suitable for winter camping.
