An homage to the efforts that make your ride possible, the Sock Guy Trail Work Wool Socks are as functional as what's on them. The socks are made from 75% TURBOwool, which is top grade Merino blended 5050 with polypropylene for a material with wool like performance properties, but at five times the strength and durability. Appropriate for riding in all four seasons, Sock Guy's wool socks will keep your feet warmer in cool weather and cooler in warm weather. Available with 6 inch cuffs in sizes SM and LXL. Made in the USA.
