Because all knees are created equal, her favorite yoga flares are now stronger, too. Thanks to Iron Knees® patches, the yoga pants girls love are now every bit as playground-ready as the boys’ pants are! In fact, our girls' yoga flares are always ready to move, thanks to a generous amount of stretchy spandex. Soft and rich in cuddly cotton, they also feature a wider waistband that doesn’t twist or pinch. Plus, they stay true to size wash after wash.
