The coolest pad you'll ever have. It's designed for every hot body with a plant-based phase change material that delivers refreshingly cool comfort for up to an hour. Relieves back aches and pains. Cools hot flashes and night sweats. May also be used in wheelchairs or hospital beds. Returns to cool state when not in use (how cool!). The Cool Pad fits inside a standard pillowcase but is safe to use directly on the skin. Latex-free and made in the USA! To clean, wash with mild soap and water then air dry.
