Built from premium Merino wool, the Cold Weather OTC (Over the Calf) Sock complements all 5.11 Tactical footwear. These premium cold weather socks offer a longer structure to improve support and prevent chafing, terry loop construction at the calf and ankle to hold in warmth while repelling cold, and enhanced arch and ankle support to maximize agility and traction over rough terrain. Moisture wicking and anti-microbial characteristics keep your feet dry and responsive, and a reinforced heel, sole, and toe increase resilience and extend garment life.
