The sports skirt has a long tradition, from tennis to field hockey. But today's activewear skirts are versatile and flattering enough for any activity. They're made of lightweight, moisture-wicking fabric and often have thoughtful touches like vents, hidden pockets and reflective strips. Some styles of sports skirts are perfect to layer over leggings in cooler weather. With wrap-and-tie construction or simply pull-on styling, these are easy garments to add to your workout ensemble. Skirts with attached panties are a one-piece solution to activewear. Look for thoughtful touches, like side slits and mesh panels for ventilation.
