Year-round comfort. Naturally engineered performance. Handcrafted in the USA, this all-season sock is designed to keep your feet warm in the winter and dry and cool in the summer—thanks to a powerful blend of bison down and silk , two of nature's most extraordinary performance fibers. With nearly double the moisture-wicking power of fine wool and exceptional breathability, your feet stay dry, sweat-free, and comfortable in any climate. Why silk? Silk is a natural thermal regulator that helps maintain your body temperature around the clock.
