Terralite

The newest addition to Western Mountaineering's Extremelite Series, the TerraLite, is a wide sleeping bag designed for comfort. It features a 12 denier ripstop nylon shell fabric with a 15 denier nylon taffeta lining material, and 850 goose down fill. There are two zippers allowing this bag to also mate with Western Mountaineering mummy bags and the second zipper opens the bag up around the foot area to lay flat. With both zippers completely open and separated, this bag also turns into a wide comforter. The extra girth in the midsection is ideal for side sleepers.
