LIGHT AND DELICATE. The Nike Yoga Tank is made with soft, sweat-wicking fabric for comfort that lasts long after practice. Flexible, dry design: stretchy, ribbed fabric with Dri-FIT technology helps keep you dry, comfortable and moving freely. Focused coverage: a curved hem with a fluted edge helps keep you covered as you bend and stretch. Vents on the sides let you move comfortably. Airy appeal: thin straps on back let your skin breathe. Fluted trim has a subtle, delicate look.
