Take on your daily route with the Nike Dri-FIT Miler Top. It features lightweight performance and mobility for the entry-level runner. This product is made with at least 50% recycled polyester fibers. All-new materials made of crimped yarn create airflow to help keep you cool. The soft feel helps cuts down on chafing during your runs. The seams at the shoulders are rolled back to help your arms move freely. A curved hem extends coverage in the back while hem vents keep you mobile.
