Sleeping well when you are backpacking requires that you sleep comfortably. The Comfort Light Insulated sleeping mat uses Air Sprung Cell technology and a hybrid matrix of offset cells to provide excellent stability and amazing comfort. There is a double layer of cells in the torso for increased comfort and warmth, and a single layer of cells in the head and legs to reduce the weight. Thermolite and Exkin Platinum are used to optimize heat retention and the multi-function valve allows simple inflation, deflation and the ability to easily fine-tune your personal comfort level.
