The J.B. Field's 40 Below Arctic Trail is one of the warmest thermal socks they make, containing 85% preshrunk wool! This style was designed for people who require a sock to keep their feet dry and warm in the most extreme conditions—as low as 40ºC!
Pair these winter socks with a liner sock to help wick away moisture and keep your feet feeling fresher, warmer, and blister-free. (These socks run large. It's recommend wearing a liner or sizing down, if possible.)
