Ultimate American Sock


Softer than Cashmere, Warmer Than Wool 

Compared to wool, bison down is warmer, better for moisture control, more durable and easier to care for. The major challenges of using bison down are it’s short staple (length of fiber) and exorbitant cost - some of the reasons why you don’t see it used more often.
