Stand Out On The Field
Stand out on the field and court in our Under Armour of boys' red athletic shirts, hoodies and tops. Constructed from sweat-wicking fabrics, these game day staples keep you cool, dry and moving freely through every sprint, dive and sprint.
Our boys’ red shirts have some great options, whether you’re looking for something to wear for training, or you need an extra layer to keep the cold at bay. Look for ColdGear®, the perfect baselayer to keep you warm and dry without being bulky or riding up, so you can stay focused all season long. Our boys’ long sleeved tops are available in a wide range of styles—fitted workout Ts, graphic Ts, hoodies, and even red polos.
Look for our red Armour Fleece® hoodies, our original performance replacement for old-school fleece. This will be your new favorite hoodie. It’s built to work just as hard as you do, and it’s super warm, with just the right amount of stretch.
Whether you’re looking for the perfect shirt to rock the court, a hoodie to wear on cool mornings on the way to school, or the perfect baselayer, we have you covered.
