The Gander Mountain Ultimate Wool Vented Hiking Crew Sock is built for all-day comfort and durability. Merino wool fabric wicks moisture away from the skin so feet stay dry and warm. Venting channels provide even greater moisture management, while the cushioned footbed offers superior impact absorption. The double-welt top cuff ensures that the sock stays up, and the seamless toe closure helps eliminate bunching for added comfort. 59% Merino wool, 38% nylon, 3% Lycra spandex fabric. Made in the USA. Sizes: M (M: 5-9 / W: 6-10); L (M: 9-12 / W: 10-12); XL (M: 12-15).
