Under Armour Baselayer & HeatGear®

Under Armour was founded on building a better t-shirt: a light, tight layer you could wear under your uniform to wick sweat, dry quick, and sit snug against your body—and it’s changed the way athletes dress for over 25 years. Since then, a lot of people have tried to imitate us, but they’ve never come close. Ours is the original, and it’s still the best. We call it HeatGear®OG.
