Running never felt so good. This revolutionary bra was designed to give you comfort, movement management, and a natural shape. Ultralu fabric is soft, smooth, and powerfully supportive. Added Lycra fibre for stretch and shape retention. Light weight, breathable, built-in cups are engineered to soften bounce. Bonded underhand won't constrict, dig in, or ride up. Stitch free hook-and-eye closure lies flat for a distraction free fit. Back closure open wide for easy removal
