The Organic Cotton Endy Sheets and Pillowcases are made from 300 thread count cotton in a single-pick, sateen weave. The thread count makes for light-weight and breathable sheets, while the sateen weave ensures they’ll get softer and comfier with every wash. Single-pick sheets are also known for their soft feel and a tight weave that offers long-term durability, so you can count on your Endy Sheets to last.
