This is the sheet set infused with silver chloride that locate and inhibit unwanted bacteria on contact. The sheets are made from an ultra-soft blend of 60% bamboo rayon-renowned for its natural bacteria resistance-and luxurious 40% long staple cotton that has been treated with microbial-inhibiting silver chloride. Heat from your body activates the sheets to release millions of silver ions which ward off bacteria, mold, mildew, and odors to create a cleaner sleep environment. Unlike lesser fabrics, the sheet's antimicrobial properties never diminish regardless of how often they are washed. The 400-thread-count, sateen-weave fabric is made without resins that can irritate sensitive skin and remains naturally wrinkle-resistant for life. Set includes a flat sheet with an extra 4" on the width, a fitted sheet with deep-pocketed adjustable corners, and two pillowcases with enveloping 8" pockets. Machine wash and dry. White.
