The minute you slip your feet into these ribbed crew socks, you will feel the softness of natural organic cotton! The organic cotton material has natural moisture absorption and heat retention, keeping your feet comfortable and warm all season long. Our organic cotton is ancient cotton that was revived by an organic farming method. It has been improved from Supima Cotton by an American biologist, Ms. Sally Fox who is known as a "cotton pioneer" for her efforts regarding organic, colored cotton. We carefully made it from the thread that contains air by a special manufacturing method that leaves the softness of fluffy cotton to the utmost limit. • Color: Cream or Latte. • Great for gift. • Size: Medium(US Women's shoe size: 5 - 9), Large (Women's 9 and up, Men's 8.5-11) • Natural Color (Undyed), No Pre-Shrink Treatment • Moisture Absorption and Heat Retention • Machine wash cold.
