Soft, Quiet Protection: This soft, quiet pillow protector is made from quiet, ultra-thin material that is breathable and maintains a comfortable sleeping temperature. The Lucid Pillow Protector has a cozy terry fabric top surface that does not change the feel or sound of the pillow while providing excellent protection against liquids, dust mites and allergens. 100 Percent Waterproof Barrier: A thin, quiet polyurethane membrane repels liquids and fluids to protect your pillow from stains. This liquid-proof barrier has tiny pores that allow air to pass for breathability and a comfortable sleep temperature. Made of safe materials, this protector is safe for children and pets. Do Away with Dust Mites: Every night your body sheds millions of skin flakes and loses up to one liter of body fluid through your pores and mouth. Because they survive on dead skin cells and bodily fluids, hundreds of thousands of dust mites can live in your pillow. Exposure to dust mites has been linked to the development of asthma in young children. Additionally, dust mites have been shown to be a leading cause of allergies and eczema. Lucid pillow protectors cut off the food supply to dust mites, making it impossible for them to survive. Machine Washable: Keep your pillow clean and fresh by washing your sleep surface. This pillow protector is machine washable and dryer safe. Machine wash hot water. Tumble dry low. Do not bleach, iron or dry clean. Color: White.
