PureCare FRíO combines our specially designed OmniGuard® Advance fabric with rapid chill cooling fibers - a micarex-based responsive textile with unique cooling properties. FRíO's rapid chill cooling fibers disperse body heat throughout the surface of the protector at a rate five times faster than that of regular polyester, focusing solely on heat reduction along the sleep surface through a combination of nano-technology, nylon, and mica minerals. The unique tunneling effect of the mineral-based fiber keeps heat from accumulating in the material surrounding the body, providing a refreshingly cooler sleep surface. FRíO's rapid chill cooling fibers are a crushed mineral-infused textile, meaning the cooling effects of this material are literally built into the fabric and will not wash out, lasting the lifetime of the protector.PureCare's clinically proven 5-Sided mattress covers fit like a fitted sheet around your mattress. Our covers utilize MiteTight® seams, combined with our OmniGuard Advance lightweight performance fabric to ensure that our mattress protectors sleep quiet and cool while providing premium mattress protection for your mattress.
