Our sateen and percale sheets are 100% cotton with no synthetic fabrics to protect them from getting wrinkled. If you dry them on low and take them out of the dryer right away that can help decrease wrinkles.
We have a new fabric called ComfortCore that you may want to check out. It is a patented hybrid fiber combining the best of all worlds: premium, long-staple, ring-spun cotton around ultra-strong, delicately textured microfilament yarn delivering durability, cotton comfort, eco-optimized for quick drying and less wrinkling.
