Combining high-tech HeatGear fabric construction and Under Armour's signature moisture transport system, the Charged Cotton No-Show Sock works to wick away moisture and accelerate evaporation so your feet stay cool, dry, and light. ArmourBlock technology helps prevent the growth of odor-causing bacteria, keeping feet fresher longer. Strategic cushioning is built into the sock for maximum shock absorption and protection, while embedded arch support reduces foot fatigue for long-wearing comfort. The HeatGear Charged Cotton No-Show Sock is made from a durable blend of 60% cotton, 30% polyester, 8% nylon, and 2% spandex fabric. Three pairs per pack. Imported.
