The Under Armour Men's HeatGear Armour Sleeveless Shirt delivers locked-in support that stays cool when training heats up. Smooth, lightweight HeatGear fabric wicks sweat fast, dries quickly, and stretches so you can move without distraction, while mesh panels enhance breathability during high-intensity sessions. 4-way stretch and ergonomic seam placement reduce chafing and keep comfort front and center.
Built for versatile workouts, this sleeveless compression layer fits easily under team gear or stands alone. Anti-odor technology helps prevent odor-causing microbes, and the smooth hem stays put through every rep, sprint, and stretch.
