Kids' Gym Wear & Training Clothes

Under Armour’s kids' gym wear for girls and boys gives you a powerful combination of tough, innovative gear that helps you train better. We built our kids' gym wear, training clothes and shoes with durable materials and advanced technologies that give you maximum support, range of motion and which eliminate distractions. That equals higher quality, more focused, and more impactful training. 

Our kids' workout clothes for boys and girls include all the gear you need for any training session. 

For maximum support and compression, our boys’ and girls’ leggings, base layers and sports bras are built using ultra-soft yet durable fabrics, which breathe at the time of sweat. We built them with advanced tech like UA HeatGear®, which is insanely quick drying, letting you focus on your workouts without distraction. 

Under Armour kids' training performancewear also includes shorts and t-shirts that are incredibly durable and sweat wicking - everything you need for grinding hard. Our hoodies and tracksuits are made with new materials like Armour Fleece®, which is lightweight and stretchy, but keeps you warm before and after training sessions. 

Our gym gear for kids' also includes essential accessories, including sweat-wicking, cushioned ankle socks, caps and headbands designed with breathable fabrics, and stable, supportive and cushioned training shoes.
