These performance socks are made from the highest-grade wool available, resulting in unmatched comfort and moisture management capability. Because the wool fibers have a natural crimp to them, they are cushiony and return to their original shape instantly. Made with just enough stretch nylon to ensure a snug fit. Non-itchy as well as being machine wash and dryable, these socks are at home inside motorcycle boots like no others we’ve tried. Grey. All are 74% luxurious, soft, durable merino wool. Crew height. M (6–8.5), L (9–11.5), XL (12–14.5).
