The men's compression short-sleeved Under Armour Tactical HeatGear® t-shirt is made of smooth fabric. Compression helps you reduce muscle wear and tear and speeds up recovery. The material used wicks away moisture and dries faster. 4-Way Stretch technology allows greater mobility of the garment in any direction. Thanks to Anti-Odor technology that prevents the growth of odor-causing bacteria, you will stay fresh for longer.
