The ultimate in comfort and warmth! Socks for the extreme weather of hiking, climbing, skiing, horseback riding and anything else extreme you can find to do! Just like the extreme boot socks but a few inches shorter. These socks will give you years of wear, but do take some extra care in washing and drying, unlike most of our socks due to the large amount of pure alpaca in them. Alpaca grown in the US, Socks manufactured in the US.
