Lightweight and Smooth Hypoallergenic and noiseless, this ultra-thin, smooth-top pillow protector safeguards your pillow without changing its feel. It is designed specifically without padding, fill, or plush fabric to maintain the feel of your pillow. Lightweight fabric protector has a quiet waterproof backing that protects the top surface of your pillow from liquids, dust mites and allergens. Breathable Barrier Soft fabric is backed by a thin polyurethane layer for protection that does not change the feel of the pillow. The waterproof layer has microscopic pores that block out liquids, mites and allergens while allowing air to pass for breathable comfort. This protector is vinyl-free and safe for children and pets. Machine wash in cold to hot water. Use mild detergent without bleach or whiteners. Do not bleach. Tumble dry on low heat with other bedding. Do not dry the protector alone. Dry on low or no heat and remove from dryer promptly. Heat settings above 125 degrees or over drying can impact the waterproof membrane. Do not iron or dry clean.
