Sea to Summit UltraLight ASC Insulated mat Sleeping

Connected air pockets are created by joining the top and bottom fabric layers with Sea to Summit's Air Sprung Cell™ dot weld pattern. By filling the UltraLight Insulated mat with a layer of THERMOLITE®, Sea to Summit created a lightweight mattress that can be used in spring, summer and autumn.The matrix of Air Sprung Cells provides unmatched support, while conforming to the contours of the sleeper. And, because these individual pockets of air function independently, when you move on the mat, you don't get that rolling feel that is common with baffle construction air mats. As a consequence these mats are simply much more stable, resulting in a better night's sleep.
