Naturepedic's proprietary DrySleep™ technology blocks liquids from passing through while allowing water vapor to escape for a cool, dry sleep. Plus, it's machine washable and dryable and one size fits most mattresses - hygienic, healthier sleep has never been easier. Naturepedic sleep essentials are made without flame retardants, formaldehyde, polyurethane foam or questionable chemicals - Only Good Things in a Naturepedic.
