Our Men’s HeatGear® Sleeveless Compression T-shirt has a famously tight fit. That’s UA Compression. It’s proven to improve circulation, speed recovery time, and boost your overall power. And, of course, our signature HeatGear® fabric keeps you cool, dry, and light no matter how hard you push yourself. But now it’s even more comfortable than ever. We’ve added a more ergonomic fit for a less abrasive feel in key impact zones—so you can focus on getting fit rather than how it fits. The Men’s HeatGear® Sleeveless Compression T isn't just an instant classic…it’s perfect.
