The Under Armour Coldgear Evo Fitted Mock design with UA's signature Moisture Transport System wicks sweat away from the body, creating an environment that is altogether more comfortable and dry. 4-way stretch fabrication allows for a greater range of motion in any desired direction. In built anti-odour technology prohibits the growth of odour causing microbes, producing a fresher, longer lasting garment. Finished with flat seam construction eliminating irritation, caused by chafing, an updated ergonomic neck provides ultimate comfort.
