Look for activewear that offers a comfortable yet supportive fit. Avoid overly loose or tight pieces; seek out articulated knees and elastic waistbands for easy movement.

Frequently asked questions
What fabrics are best for kids' activewear?
We recommend moisture-wicking blends like cotton-polyester or bamboo. These fabrics keep kids dry and comfortable by drawing sweat away from the skin.
How should kids' gym clothes fit?
Aim for a snug but not tight fit. Ensure there's enough room for movement, especially in the shoulders and thighs, without excess fabric that could cause tripping.
Can I use fabric softener on activewear?
We advise against fabric softeners as they can clog the fibers and reduce moisture-wicking abilities. Stick to mild detergents for best performance.
How often should I replace kids' activewear?
Replace pieces when they show signs of wear like thinning fabric or loose seams, usually every 6-12 months, depending on frequency of use and growth spurts.
