Mountain Hardwear Switch 20

Mountain Hardwear's Switch 20� Sleeping Bag features warm, Thermolite Extra insulation, which is a highly compressible insulation consisting of hollow-core fibers that provide three-dimensional spring-like loft. This explains its low weight together with superior warmth and resiliency. In order to provide extra comfort for those long nights in your bag, the Switch has the Quantum expander allowing you to increase bag girth by 8� with a fully insulated panel so it doesn't create a cold spot when open. The Switch 20� is an outstanding choice in cold to moderate temperatures where moisture and compressibility are issues.
