A comfortable backcountry pad providing winter insulation and all-season comfort, now offered in a 4-pack for group outings or added convenience. 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.
