The Under Armour HeatGear Compression Long Sleeve Top is built for performance. This long-sleeve boasts super-light HeatGear fabric, delivering superior coverage without weighing the wearer down. Mesh panels provide strategic ventilation, while the material wicks away sweat and dries quickly. Anti-odor technology prevents the growth of odor-causing microbes, and the ergonomic design keeps seams off high-abrasion areas.
