Sports and outdoor clothing for girls

Upgrade her athletic wardrobe with our full line of girls' activewear. Moisture-wicking synthetic fabrics draw sweat away from the skin to prevent post-workout chills, while durable stretch textiles hold up through weekly machine washes. Designed for total comfort, our sports t-shirts feature flatlock seams that won't chafe or irritate under the arms.

Dress her for winter with Decathlon

Our girls' winter clothing relies on the three-layer system: a breathable merino wool base layer, a warm polar fleece sweater on top, and an insulated jacket to brave the cold.
