The Under Armour UA HG Armour Comp SS-GRN Men's T-Shirt is made of extra-light HeatGear material, which provides perfect coverage without restrictions. Mesh panels on the back and underarms provide strategic ventilation. The material wicks sweat and dries quickly, so you stay fresh even after a demanding sports performance. Ergonomic cut with seams outside the most stressed areas increases durability and comfort without chafing. Hybrid raglan sleeves allow maximum freedom of movement.
