The Under Armour Men's HeatGear Armour Short Sleeve Shirt is a lightweight base layer built to keep you cool, dry, and moving freely. Smooth fabric wicks sweat, dries fast, and stretches with your motion, while a streamlined fit layers comfortably under uniforms or workout gear.
Mesh panels enhance breathability in key heat zones, and ergonomic seams reduce chafing during high-intensity sessions. A shaped, slightly longer hem adds coverage that stays put when you bend, lift, or sprint—giving you reliable comfort from warmups to cooldown.
