Game-Changing Boys’ Tops

Under Armour changed the game by swapping out heavy, sweat-drenched T-shirts for ones that wicked sweat, dried fast, and stayed light so they wouldn’t weigh you down. From our HeatGear® baselayers to polos, to sweatshirts, our boys’ tops keep you comfortable and focused on your game and training. We make boys’ shirts for every sport. Tank tops for summer pickup games. Long sleeve shirts for boys, good for cool morning practices. Hoodies for boys that are perfect for between-season training, or just hanging out with friends. Plus, baselayers to wear under uniforms, and even graphic T’s that represent the work you’re putting in day in and day out to be better.

When you train, it’s the little details that make a difference. Correct form on a lift. Proper footing on the field.. With boys’ Under Armour shirts, it’s the details that make them pop. Check out boys’ workout shirts with UA Tech™ fabric that’s made to stay light, loose, and keep you cool with a natural feel. Other options with ColdGear® or HeatGear® help you stay warm in the cold and cool in the heat, serving as the perfect baselayer under your gear.

Get the classic feeling of fleece, just better. Hoodies for boys with Armour Fleece® are our original replacement for that old-school fleece. They’re light, incredibly warm, and stretch so you can move comfortably. Pair your long sleeve shirts for boys and other boys’ workout shirts with lightweight shorts or joggers and sweatpants. And, check out accessories like boys’ socks that help keep your feet cool and dry even during the hardest workouts.
