The Bison Trail Sock is responsibly made with bison wool, recycled polyester, wool, and spandex for the best all around sock there is. United by Blue humanely salvages buffalo fiber that would otherwise be discarded, and the benefits of this underutilized fiber are truly amazing. In particular, UBB’s proprietary BisonShield material is temperature regulating, extremely flexible and lightweight, and even keeps its warmth when wet.
The Bison Trail Sock is guaranteed to keep your feet sweet because of the reinforcement around the sole, heel and toes, and the ribbed compression throughout. This crew sock is the perfect sustainable option whether summiting a mountain or kicking back on the couch.
The Bison Trail Sock is a eco-friendly masterpiece. These socks are designed for every season, as the slim size and temperature regulating properties allow for snowy and balmy hikes alike
