The 20-Degree Mummy Bag is built for cold-weather camping, combining 1000 fill power grey goose down—treated with a DWR finish—with 3-dimensional baffles that loft to 2.75 inches for efficient heat retention. The ultralight 7D micro-ripstop nylon shell and lining keep weight minimal while maintaining breathability and durability across cooler-season conditions. Draft tubes along the zipper, neck, and hood seal out cold air, and a parka-style hood with cinch cords ensures a close, comfortable fit. Continuous horizontal baffles let you redistribute insulation as temperatures shift, and a chest pocket keeps small essentials accessible through the night.
