Offering superior strength and softness beyond most Egyptian cottons, Supima® cotton combines with naturally moisture wicking TENCEL® to manage temperature as you sleep. Supima is able to authenticate its cotton across the entire supply from the fiber and yarn to the fabric and finished product at retail. This complete transparency enables an open dialogue about all relevant facts, including point of origin, sustainability, and social and economic responsibility aspects. Supima’s transparency is based on forensic science analysis of the natural fiber itself revealing its place of origin. TENCEL® is spun from fibres derived from certified Eucalyptus wood pulp that is treated in a "closed-loop" manner, making it safe and sustainable.
