The Ultralight sleeping mat range has a single layer of medium resolution Air Sprung Cells to give you the lightest and smallest packaged amount of mat without compromising comfort. To add heat, we use Exkin Platinum, a quiet non-woven fabric that reflects radiant heat loss back to the user and prevent Thermolite insulation convection heat loss between your body and the ground. All Sea to Summit sleeping mats come with a quality stuff bag, a repair kit with six self-adhesive patches for repairing holes in the field, and a spare silicone one-way valve flap.
