The Comfort Plus(TM) air sleeping mat is the non-insulated dual layer version using the award-winning Air Sprung Cell(TM) technology. With two separate layers of interlocking air chambers, the sleeper can fine-tune the top layer to perfection, and adjust the base layer to accommodate for rough terrain. There is also a built-in redundancy in that, if one side of the mat punctures, the other is still able to function until a repair is made. Perfecting your desired comfort level is super simple with the multi-function valve on both layers of the mat.
