BUILT FOR ALL-DAY COMFORT AND PERFORMANCE. The Nike One Tights are designed for all-day wear not just for training. They blend soft, durable fabric with sweat-wicking technology to help keep you dry and comfortable whether you're working out or hanging out. Dry Design. Dri-FIT technology moves sweat from your skin for quicker evaporation to help you stay dry and comfortable. Shape-Hugging Comfort. Stretchy design with a mid-rise, contoured waistband follows the natural lines of your body for a smooth feel. Sleek Storage. A slide-in pocket at the back waist is large enough for your phone, while a drop-in inner pocket at the side stores your keys and cards.
