Restore & Calm products are designed to keep your temperature cool and steady throughout the night using our Ultra-Tech with Tencel fabric. No more tossing and turning or kicking your feet in and out of the covers to get to your desired temperature. Tencel is not only naturally hygienic for sensitive skin but also environmentally sustainable. In addition, Tencel is 50% more effective than cotton at wicking moisture away from your body allowing you to sleep dry.
