Using naturally odor-resistant and temperature-regulating merino wool as well as odor-fighting silver and carbon fibers, ScentLoks Mens Merino Hiking Socks give your feet a fighting chance to stay fresh on the trail. Moisture-wicking design transports perspiration away from your skin so your feet dont sit in sweat all day. Compression caps keep them from sliding down your leg, while a bridge compression zone keeps them secure inside your boots so they dont get bunched. Padded toes are great for descents, while padded ankles keep footwear from chafing. 66% merino wool, 28% nylon, 3% silver nylon, 2% Lycra spandex and 1% carbon nylon. Imported. Mens sizes: M(5.5-8.5), L(9-12). Color: Charcoal.
