The Helinox Insulated Cot Pad transforms our Cot One Convertible into an all-season haven, providing a warm, comfortable night of sleep any time of year. The R-value of 5 allows us to confidently head out to our favorite winter campsite, knowing we will get a great night of rest. The durable polyester ripstop is tear-resistant and made to stand up to harsh conditions, and as we pack up camp the pad packs down small into the included cinch bag for easy transport and storage.
