This 90% polyester, 10% spandex pant has an adjustable elastic waistband with drawcords that have reflective specs, stretch woven fabric, adjustable bungee cords at the ankle with adjustable stopper, and inserts with a unique all over metallic foil coating. Please ensure to follow the care instructions to lengthen the life of this special coating. The Zumba Reflective Track Pants offer maximum style with metallic foil inserts and luxe branded details, but you'll notice we didn't skimp on the functional details like pockets and adjustable elastic cuffs either.
