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. Features side rails that are integrated into the patterning and construction for secure and comfortable sleep. They center you on the pad and inhibit air movement while tossing and turning. The chambers are filled with light, lofty Klymalite synthetic insulation to add another layer of protection from the cold ground. Deep Weld patterning creates expansion zones that allow the pad to fully loft beneath you for improved thermal comfort.
