built for adventurers who demand extra warmth. This lightweight, backcountry-ready pad provides winter insulation and true four-season performance with an impressive ASTM R-Value of 4.2. Multiple reflective film layers and Klymalit synthetic insulation work together to block cold from below, while dynamic side rails keep you securely centered for a deeper, more restful sleep. When it’s time to pack up, it rolls down small for easy carry anywhere your adventure takes you. As part of the Peak Series, this pad is engineered for experienced adventurers who demand the highest level of warmth, refinement, and four-season performance.
