For weeks, the internet has been talking (and swooning!) about Heated Rivalry star Francois Arnaud and his viral Under Armour HeatGear® compression shirts (episode 3 anyone?!). 

 

HeatGear® is our original performance baselayer that changed the way athletes dressed forever back in 1996. It’s a second skin full of advantages, making you look and feel powerful the moment you put it on. We introduced ColdGear® a year later, offering the same lightweight, sweat wicking material, but designed to keep you warm in cold weather. 

Nothing Hits like the OG

We can’t blame you for wanting to cop the look, but before you jump in, let us give you the UA compression shirt playbook. 

 

Compression isn't just about looking good—it's about being prepared for whatever climate your day (or your rival) throws at you. That’s why we offer performance baselayer for the hottest and coldest conditions.

🔥 HeatGear®: The Look That Stays Cool🔥

HeatGear® Crewneck

This is the gear that keeps you cool when the temperature—and the tension—is rising. Our light and tight fabric wicks sweat away and dries fast so you stay cooler. The 4-way stretch material lets you move in any direction without bunching or pinching. It's the original performance layer you put on first and take off last.

 

The sleek, performance-ready foundation for any hot weather look. It keeps you cool when it's hot, making you look like you're putting in zero effort while everyone else is melting.
