The Heated Rivalry Style Files: Your Guide to Nailing the Viral Compression Shirt Look

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.

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🔥

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.

❄️ ColdGear®: Warmth That Keeps Its Promise ❄️

When the cold hits, you don't pile on the bulk—you put on the right layer. ColdGear is designed to be your cozy secret weapon, keeping you warm without sacrificing mobility.

A clean, compressed fit that makes you feel (and look) strong and agile. The brushed inside traps heat to keep you warm without adding weight or bulk so you can stay agile. This style always features a mock neck for extra coverage and warmth.

Skiing, snowboarding, hockey 😉 or that freezing early-morning run.

Under your hoodie or jacket when walking to and from the gym.

Anytime the temperature dips into "I need a blanket" territory.

These compression looks are available for men , women , youth , and in shorts and leggings too! Under Armour’s got you covered no matter what you’re doing, where you’re going, or what vibe you’re going for.
