The smarter way to sleep

Climarest® uses phase change materials (PCMs) – originally developed to safeguard astronauts from extreme temperature fluctuations in space – to absorb heat when you’re hot and release it when you’re cold, helping you maintain a comfortable temperature all night long. We printed phase change materials right on top of the pure cotton face of this comforter, then filled it with soft and lofty polyester for well-balanced support.
