The Nike Women's Yoga Ruche Tank combines soft, ribbed fabric with sweat-wicking technology to keep you dry and comfortable. There's a little bit of stretch and ruching at the size to keep you in the flow. The higher neckline in the front helps you stay covered through your poses. Nike Dri-FIT technology moves sweat from your skin for quicker evaporation, helping you stay dry, comfortable and focused. Ruching on the sides keeps the cut close to your body to stay out of the way while you move. A higher neckline in the front helps you stay covered during downward dog and other stretches. A lower cut on the back makes it breathable.
