Baselayer

UA took their sweat-wicking, keeps-you-cool technology and turned it into the best underwear in the game. It feels cool, stays put, and provides a zero-distraction fit that's snug, but not tight.

HeatGear Armour is UA's original performance baselayer - the one you put on first and take off last. So they made it extra comfortable by wicking sweat and stretching so you can move no matter what.

We all hate it. That stiff, distracted feeling you get when you're out in the cold. That's why UA built a baselayer that keeps you warm and dry without being bulky or riding up, so you can stay focused all season long.
