Marled yarns are formed by twisting together plies of different colors. The result is a single strand of yarn with multiple colors winding around one another. We chose our colors with a strong value contrast for a vibrant, jazzy appearance. These cotton-rich socks add nylon, polyester and a touch of spandex for resilience and shape retention. 69% Cotton, 22% Rayon, 6% Polyester, 3% Elastic. Machine wash. Imported.
