Womens New Balance Perfect Tank :: The New Balance Perfect Tank couldnt be more flattering. A lightweight, space dye poly/spandex fabric is now even softer to the touch. Its tunic length and ruching on the side seams, plus, racerback straps with a keyhole cutout adds feminine flair. NB DRY helps wick away sweat fast, while a reflective logo at the center back lets the world know you mean business.
