Using patented technology developed for NASA, this is the blanket that absorbs, stores, and releases heat to prevent chills or overheating. Imbedded in the blanket are millions of invisible microcapsules that absorb excess heat when one is hot and release the stored heat when one is cold, ensuring a comfortable temperature throughout the night. The temperature regulating technology is ideal for couples with varying body temperatures, as it will adjust to each sleeper’s individual micro-climate. Made with a 50% polyester/50% Outlast acrylic fill and a soft 100% cotton exterior. Machine washable and dryable.
