Try it once and you'll never run in anything else. The Under Armour Charged Wool Running T-Shirt is constructed with Charged Wool, which is soft like regular wool, but dries much faster with its embedded Moisture Transport System that wicks sweat away from the body to be evaporated from the surface of the garment. This coincides with Anti-odour technology prevents the growth of odour-causing microbes to keep you smelling and feeling fresh.
