At 96% organic cotton, these everyday socks have one of the highest percentages of cotton of any socks we sell. Cotton is known to be soft and breathable, making it a comfortable sock year-round, and the GOTS-certified organic cotton makes these the eco-friendly choice. The Global Organic Textile Standard (GOTS) ensures that the raw materials are processed in an environmentally sustainable and socially responsible way. Only textile products that contain a minimum of 70% organic fibers can become GOTS certified.
