The Mens Smartwool Adventure Socks are classic marl socks. Made of New Zealand Wool, the Adventurer Socks are naturally antimicrobial to fend off odor; temperature regulating to keep cold feet warm and warm feet cool; and wicking to provide moisture management for dry comfortable feet. These SmartWool Lifestyle Mountain Socks feature comfortable true rib construction and a hint of color along the top cuff. Featuring WOW Technology™, the Adventurers have more wool in high-abrasion areas, which means more comfort and more durability. The SmartWool Adventurer Socks offer all-day comfort with rugged sophistication.
