The All-In-One Rayon from Bamboo Comfort Pillow Protector with Bed Bug Blocker, provides powerful protection against bed bugs, dust mites and other allergen irritants. We begin with a soft knit Rayon from Bamboo-derived cotton-blend fabric and line it with a special permanent coating. This coating, along with our double sewn seams, provides a complete barrier. The pillow protector has an inner flap, a easy closure closure and zipper to block bed bugs and dust mites, as well as allergy irritants. Rayon from Bamboo-derived cotton-blend fabric sleeps cool and wicks moisture for an optimal sleep experience. The pillow protector is available in King and Standard/Queen.
