The Merino Ski+ Light Over the Calf Mountain Contour socks are durable, stretchy and highly breathable socks for skiing the resort or the backcountry. The strategically cushioned design features a blend of merino wool, nylon and elastane that's anatomically sculpted with key support zones in the ankle, Achilles, and instep. The breathe zone increases ventilation, and the seamless toe reduces bulk and prevents blisters. The all-over print draws inspiration from the intricate patterns of a mountain's elevation lines. Inspired by nature, icebreaker harnesses the performance qualities of natural fibers to offer an alternative to clothing based on petrochemical synthetics. Merino wool is an annually renewable fiber that naturally resists odors, keeps you cool when it's hot and warm when it's not, and lets your skin breathe for comfort all day, every day.
