A comfortable backcountry pad providing winter insulation and all-season comfort, the Insulated Static V packs light and small and delivers an outstanding R Value of 4.4. The body-mapped shape and V chamber design combine to maintain comfort and minimize air movement that can impact insulation. The chambers are filled with light, lofty Klymalite synthetic insulation to add another layer of protection from the cold ground, and dynamic side rails cradle you comfortably on your pad for a more restful sleep.
