Organic cotton-blended Yak Ribbed Socks knitted on a vintage double-cylinder low-gauge knitting machine, are crafted for comfort, design, and durability. Slightly longer in length, these versatile socks are ideal for formal occasions. Tibetan yak hair is used to create an elegant, dark-gray hue, its excellent heat retention and moisture-absorption properties perfect for year-round wear whether indoors or out. With no prickly wool or piling, these socks are as luxuriously comfortable in the chill of winter as they are in the warmth of summer.
