Like many of our stylish , Hipkini's sheer yoga leggings are made of silky to the touch Brazilian Supplex (Polymide/Elastine). That makes these sexy black and white workout leggings fast drying and adds lots of stretch to adjust to your perfect fit. These sheer workout leggings have the performance benefits of modern fiber technology. SUPPLEX fabrics are breathable, hold their shape, dry faster than cotton and retain their color.
