We took the extra fine cotton fibers called virgin cotton that remain after yarn is produced and ran it through a specialized spinning machine. In addition, we combined this special yarn with silk thread. Enjoy both the smooth texture of silk and the softness of cotton. These crew-type socks are fluffy and comfy ? ideal to wear from spring to summer. The silk absorbs sweat leaving the feet to indulge in the smooth texture of the material. The playful two-color design adds an accent to any outfit.
