Boys’ Athletic Clothes for All Sports

Built for a fresh look when you’re in the hallways and in the classroom. Made to keep you comfortable when things get heated during recess and on the field. Made for after school, Summer, and weekend practices or hangouts. Under Armour boys’ athletic clothes combine the materials needed to keep you going with designs and styles that show you mean business. Our boys’ sportswear stays comfortable from the first rep to the last, while our boys’ sports gear gives you what you need to push the envelope just a bit more. You’re working to be the best, no matter where you are. We’re working to help you get there—and stay there.

You look for it, we got it. From sweat-wicking T-shirts to lightweight football cleats made for every route, Under Armour boys’ athletic clothes and boys’ sports gear make you better. Find shorts UA Storm technology, which repels water and keeps you dry. Check out others that have encased elastic waistbands for a totally customizable fit, and more with lightweight mesh fabric that are perfect for a new go-to pair of shorts. Stay warm with fleece pants and joggers that won’t hold you down with added weight.

Armour Fleece® boys’ athletic clothes like hoodies are light, breathable, and stretchy so you can move freely and comfortably at all times. Show the personality with boys’ sports clothes like graphic T-shirts. Made to dry fast and stay soft, wearing one of these while out on the field with friends will show them what you’re about. Whether it’s school pictures or just wanting to dress more casual, our boys’ sportswear polos are clean-fitting with low-profile collars and plackets. They don’t pill or chafe, either.

Combo our boys’ athletic clothes with Under Armour boys’ shoes. Check out super grippy basketball shoes with cushioning that absorbs impact and returns energy for more explosiveness. Or, boys’ baseball cleats that dig into the ground and give you premium stability around the bases and in the field. Ventilated, lightweight running shoes, golf shoes, and more, we’ve got what you’re looking for.
