The Nike Dri-FIT Miler Women's Short-Sleeve Running Top is made for the long haul. Sweat-wicking fabric helps keep you dry, while an ultra-breathable construction helps keep you cool, for total comfort from mile one to done. Stay Dry Dri-FIT Technology helps keep you dry and comfortable by wicking sweat away from your skin to the fabric's surface, where it quickly evaporates. Stay Cool Mesh throughout the back helps your body heat escape so you can stay cool. Stay Comfortable Raglan sleeves allow you to move your arms freely and fully. Seamless shoulders provide a smooth feel, especially if you wear a backpack.
