Boys' Sportswear & Gym Clothing

You’ve set your targets. Now it’s all about the grit, the grind, the hard work. Under Armour boys’ sportswear gives you pro-grade gear that helps you train better. Our boys' sports gear and shoes are built with advanced technologies and tough materials that boost your performance and help you train harder, longer and faster. 

We’ve built boys’ gym wear and performancewear for all popular sports, including running, athletics, gym training, football, basketball, and golf. Our range includes all sports wear for boys that you need for every season - including base layers, shorts, t-shirts, tracksuits, jackets, hoodies, shoes, socks, bags and hats. 

Under Armour boys’ sportswear helps you train better because we use professional grade fabrics that let you push your limits. You’ll find tech like HeatGear®, a performance baselayer built for warm weather training, that keeps you cool while letting sweat wick extra fast. For winter sessions, ColdGear® keeps you warm, while remaining highly breathable and without adding bulk. We use UA Storm on many of our boys’ sports clothing - it’s a treatment that keeps you dry, but means our trousers and jackets are still breathable so you can keep training in comfort. 

Our boys' sports shoes boost your performance by using advanced technologies and designs that help you play better. UA Magnetico football boots require zero break-in, so you can get back to training without blisters. We built our boys running shoes using UA HOVR™ cushioning, which is incredibly springy and durable. And our boys’ basketball shoes include tech like UA Flow - a rubberless grip and cushioning system, for fast, lightweight flowing movement across court. 

Browse our performancewear for boys, and find the gear you need to smash your targets.
