Cool Rapid Sweat-Absorbing & Quick-Drying Bedwetting Sheet for Single Bed Size: 100 x 210cm Quickly absorbs and wicks away sweat, providing a dry feel and the cooling effect of evaporative cooling. The back side is polyurethane coated for thorough waterproofing, preventing moisture from passing through and catching it securely! I bought several of these when my child was small, but one was left unopened in the dresser. Please refrain from purchasing if you are concerned as this is a home-stored item. Thank you. #BedwettingSheet
