Under Armour’s kids’ sports clothes give you high quality, durable and comfortable gear that helps you train without distraction, meaning you can play at your best. Our kids sports clothes include a complete range of gear for boys and girls, including kids tops, bottoms, shoes, socks, hats, bags and accessories for all popular activities. 

We’ve built our kids’ gym wear and sports clothes with some of our most advanced materials to ensure you get all the support, comfort and flexibility you need. Take our kids gym shoes and running shoes. They’re super lightweight, but have superior cushioning which protects your feet from impacts. Our kids tops are built using highly breathable fabrics that wick sweat away from your skin, so you feel fresh and dry when working out. Kids Under Armour tracksuits give you the perfect combination of warmth and comfort, but are also breathable so you can wear them during training. 

We packed our kids sportswear with Under Armour tech so you can train better. These include HeatGear®, a material designed for warm weather workouts and keeps you cool. There’s also Iso-Chill, a fabric with fibres that feel cool to the touch. And there’s ColdGear® - our flexible winter wear that keeps you warm without restricting movement.
