The silky-soft sateen weave fitted sheet includes a continuous elastic hem so bed-making is easy and your sheet hugs your mattress just right. Soft and comfortable against your skin, it is made with their exclusive, sustainable CleanBamboo® fabric. Their fabrics are made from organic bamboo using their patented closed-loop process with food-grade, non-toxic solvents. This process produces a unique 100% bamboo lyocell free from harmful chemicals and plastics, unlike other bamboo viscose and bamboo/poly blends on the market.
