J.B. Field's J.B. Fields Unisex's Winter 40 Below Socks, Green, Medium

Description The -40 Below Artic Trail is one of the warmest socks we make and contains an astonishing 85% wool. THIS IS A STEAL WHEN COMPARED WITH WIGAM -40 BELOW SOCK @ $10 A PAIR AND ONLY 50% WOOL. It was designed for people who require a sock that can keep their feet dry and warm in the most extreme conditions. We recommend wearing a liner sock to help wick away moisture because it will keep your feet smelling fresher, warmer and blister free! If you are unsure about what sock to buy we would recommend the -30 below as they are much softer/comfortable because they are made from Merino Wool. However, that said the -40 and -50 below socks will keep you warmer but were really designed as a rugged sock to be worn outside in boots.
