Warm enough for moderately cold winter camping, and chilly autumn nights.

The Yeti series of sleeping bags are designed for winter mountaineering. With a well insulated mat underneath the Yeti -20 is good in temperatures down to -20°C (-8°F). A DWR coating on a tough nylon shell provides protection from condensation inside a tent. Rectangular baffles are filled with with 700+ fill power goose down for reliable warmth and good compressibility. There's a draft tube along the inside of the zipper and around the shoulders to block the cold out plus a snorkel tube around the face.  Full length zippers allow two mummy bags to be zipped together (one a L-hand zipper, the mate a R-hand zipper). The toe box is longer on top for a more natural foot position and toasty toes.
