HeatGear, the original high-performance baselayer from Under Armour, is the first thing you put on and the last thing you take off. That's why this men's T-shirt was made to be extra comfortable. The material wicks away sweat and stretches so you can move freely. The extra-lightweight and odor-resistant HeatGear fabric provides excellent coverage, wicks sweat and dries very quickly. Mesh panels under the arms and at the back provide strategic ventilation. Ergonomic cut with seams outside high-wear areas increases durability. Hybrid raglan sleeve design ensures natural freedom of movement and superior comfort.
