By regulating a thermal balance, the OutlastÂ® cotton cover helps you sleep undisturbed. This material was originally developed for NASA to balance temperature changes, and it absorbs, stores, and releases heat during sleep stages. Excess heat will be absorbed and distributed throughout the fabric, but when the body temperature cools, it will be released. Throughout the night, natural temperature changes are buffered by this method.
