Made out of a combination of spandex and polyester, the ASICS women's SILVER KNEE TIGHT running tights offer unhindered movement and superior comfort thanks to flat seaming which helps to reduce the risk of chafing. Other notable features include improved moisture management technology, a flat elasticated waistband with drawcord for easy adjustability, a handy hidden internal pocket for the convenient storage of personal items and reflective ASICS branding for enhanced visibility when running on the roads.
