This pillow protector is the ideal solution for protecting your non-washable pillows from spills and stains. Unlike most pillow protectors which are not waterproof and lack protection from accidents involving liquids, this pillow protector features a waterproof barrier and is tailored similar to a pillowcase with one side open so air can easily flow in and out. Made with two layers of soft organic cotton jersey and an ultra-thin waterproof barrier in the center, the protector easily stretches to maintain the comfort of your pillow. Features DrySleep™ technology, which effectively blocks liquids from passing through while allowing some water vapor to escape. This results in a more comfortable and breathable fabric. Also creates an impenetrable barrier to dust-mites, lice, bed bugs and allergens, making it perfect for use while traveling. Machine wash & dry.
