This is the cooling pillow that keeps sleepers continuously comfortable throughout the night by using chill textile technology from the inside out. The interior of the pillow is treated with quick-chill phase-change technology (PCM) designed to absorb heat energy the moment you rest your head, delivering up to 10x more cooling relief than untreated fabrics of its kind. The cover is a blend of Tencel and Lyocell and Frio rapid chill cooling fibers tested to cool up to five times faster than polyester. The down-alternative fill provides the cloudlike softness and adjustability of traditional down, making it extra supportive to back and side sleepers. An exclusive treatment applied to each fiber actively wicks moisture away, creating a cooling effect that helps keep you dry and comfortable. The hypoallergenic pillow receives an antimicrobial treatment that inhibits bacteria, mold, and mildew that cause deterioration, stains, and odors. Certified by Oeko-Tex 100 to be free of skin-irritating chemicals and substances. Medium loft. Made in the U.S.A.
