Made with OEKO-TEX certified non-toxic dyes. Supima is a type of cotton that has more flexible and longer fibers than other cottons. This cotton was first grown and cultivated by a Native American tribe known as the Pima. It’s still grown in some small areas of the USA. The word “Supima” is a combination of the words “Pima” and “Superior”. Our scarves use the rare Supima cotton grown in Alvares Farm, New Mexico. GOTS Certified by CU812575
