Combining high-tech HeatGear fabric construction and Under Armour's signature moisture transport system, the Brights No-Show Liner 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. Embedded arch support helps reduce foot fatigue, while the True Seamless Toe provides additional comfort. The HeatGear Brights No-Show Liner is made from a durable blend of 92% polyester, 3% nylon, and 4% spandex fabric. Six pairs per pack. Imported.
