The Nike Women's Swift Novelty Breathe Short Sleeve is made for any and all miles. Ultralightweight and sweat-wicking with small reflective details, it helps keep you cool and comfortable through your runs while adding a little bit of visibility to your runs. It has a barely-there feel, making it a great option for putting in the miles or heading out for a training session. With a loose, light fit, you won't even notice it's there, helping you keep your focus where you need it.
