Kids' Athletic Sports Clothes

Are you taking your sport to the next level? It’s going to take grit, hard work and determination. Under Armour kids' athletic wear is built to help boys and girls train better - at school, at sports clubs, and at competitive events. Designed with advanced technologies, tough designs and innovative materials, it allows you to train more effectively and efficiently. 

Our kids' performancewear gives you all the gear you need to push your limits with your sport. Under Armour performancewear for boys and girls includes a complete range of sports gear, including base layers, leggings, shorts, trousers, t-shirts, tops, hoodies, tracksuits and jackets. 

All our kids' athletic wear uses technical materials that are lightweight, breathable, and which wick sweat fast. We packed our kids' athletic clothes with innovative tech, like UA Storm which keeps you dry in the rain while letting your skin breathe. Or UA Tech™, a lightweight and soft fabric that dries fast so you can focus on your game. For warm weather, UA HeatGear® keeps you cool and fresh, while UA ColdGear® means you stay insulated without adding bulk. 

Under Armour kids' sportswear also includes a complete range of footwear for all popular sports, including running, training, golf, football, and basketball. We built them using game-changing technologies like Charged Cushioning®, an incredibly responsive and durable midsole, tough rubber outsoles, or midfoot wraps which hold your feet securely in place. 

Browse our kids' athletic wear, and find gear that helps you progress to the next level.
