WATERPROOF, ALLERGEN, DUST MITE & BED BUG PROOF ALL IN ONE PROTECTION One protector to do it all. This protector is cleverly designed with a waterproof surface to protect your pillow. Dust mite proof airflow panels at each end allow the pillow to rise and fall naturally while directing air away from the face. FABRIC MADE IN EUROPE The center surfaces are made from a fabric with outer layers of organic 100% cotton knitted jersey fabric with a Neotherm® center. Neotherm® is a proprietary polyurethane that is both waterproof and yet breathable. The highly breathable airflow panels at each end are made of a 220 TC long staple cotton tightly woven to be dust mite proof. Note: end panels are not waterproof. European fabrics are superior because of advanced technology and regulations for non-toxic processes. SELF LOCKING ZIPPER The special self locking zipper keeps bed bugs and dust mites out of your bedding because it locks in place when you close and release the tab.
