DESC: The Mountain Hardwear Switch 20 Sleeping Bag is a 20 degree synthetic fill bag perfect for three season camping. Filled with Thermic MX, the Switch 20 offers an excellent value and is very compressible for the weight and warmth. The mummy cut is more comfortable and more efficient than a rectangular cut. But for those times where more room is required, Mountain Hardwear's Quantum expander can be zipped open to increase the bag girth by 8 inches! A Face Gasket seals in heat around the face and neck, so you stay nice and warm during your sleep. The Comfort Footbox of this Mountain Hardwear sleeping bag follows the natural position of the foot for improved fit and warmth. When you need an outstanding choice for your cold weather adventure, switch to the Mountain Hardwear Switch 20 Sleeping bag. Available at TravelCountry.com.
