I do not need to explain Bison Socks to all who gained experience with Bison Gloves. I advise all others to ask the happy owners of those gloves about the warmth retention. Many seem to have done so already, because they are selling like hot cakes since the first cold spell. For the Bison Socks a yarn of yak and bison is used because it makes them exeptionally durable.
