Made exclusively of 100 percent American-grown extra-long staple cotton, this makes our new Supima sheet set the perfect premier sheeting option for your bed. Featuring a lustrous sateen weave, these new 600-thread-count sheets drape beautifully. Supima cotton is finely woven and mercerized to create fabric that is softer, more vibrantly colored, breathable, and remarkably pill resistant. Crafted with extra-deep pockets for thicker and pillowtop mattresses, your customers will love our Universal Fit™ guarantee. Unlike Egyptian cotton, which does not denote any quality attributes, Supima cotton is a protected and verified fiber. Our sheets are protected with a five-year warranty against manufacturer defects like piling, so your customers can purchase with confidence.
