Previously rated at a conservative 15 degrees and now sporting a full draft collar, the astonishingly light Western Mountaineering VersaLite Super is now rated as a 10 degree bag. The VersaLite contains 20 ounces of high loft 850 down fill for a full 6 inches of loft. Despite weighing only 2 pounds, the Versalite boasts a roomy 62 inches of shoulder girth. Western Mountaineering calendared the Versalite Supers ripstop nylon shell to keep feathers from escaping the mother ship and increase the life of your bag. The silky smooth taffeta lining soothes your skin and breathes like a yogi so you stay warm but dont cook your goose. Take proper care of the Western Mountain Versalite Super and be grateful for decades to come.
