Kids’ Large Size Clothes for Athletes

Under Armour kids’ extended size clothing gives you the gear that’ll best suit you and your goals. These kids’ large size clothes are set to perform in all seasons, in all sports, and in everything every day has to offer.

That means you’ll find T-shirts with our UA Tech™ fabric built to wick away sweat and dry fast. Kids’ extended size clothes like polos and golf pants look great on the course, sure, but they’re dynamic enough to wear comfortably school day after school day, too. Stretchy fabrics in all our pants—from golf ones to fleece joggers—let you move better in every direction. Your swing stays fluid. Your strides on the track go uninterrupted. And everything in-between? Smooth as ever.

Kids’ clothes aren’t complete without graphic T-shirts, shorts, and other options. Nothing says being an athlete more than putting the work in on the field and representing it when you’re off the field. Our graphic clothing in kids’ extended sizes comes with things like light, soft, and quick-drying fabrics to keep you good to go throughout the day. They also feature colorful graphics of all styles that really make them pop. Look for boys’ extended size clothing and girls’ extended size clothing built with soft, cotton-blend fabrics for all-day comfort, as well as ribbed collars for a better feel.
