The Pr1me® Smooth Pillow Protector protects you and your pillow with a 100 percent waterproof layer that guards against all liquid spills. Soft, smooth fabric is backed by a breathable polyurethane membrane that allows airs to pass while effectively blocking fluids, dust mites and allergens. With a pillowcase design and zippered end, this protector goes on easily and fits without shifting or bunching. It can be easily removed and machine washed to keep your sleep environment clean and fresh. Best of all, the SLEEP TITE PR1ME Smooth protector is cooler and quieter, giving you complete protection without changing the feel of your pillow.
