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 50/50 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 S/M and L/XL. Made in the USA.
