LIGHT AND MOBILE. Take on your route with the Nike Dri-FIT Miler Tank. It has lightweight performance and mobility for the entry-level runner. This product is made with at least 50% recycled polyester fabric. Ventilated flow: an all-new fabric made of crimped yarn creates airflow to help keep you cool. Its soft feel helps cuts down on chafing during runs. Keep it moving: the seams at the shoulders are rolled back to help your arms move freely. A slightly curved hem extends the coverage in the back while side vents keep you mobile. Dri-FIT technology helps you stay dry and comfortable. Designed with a standard fit for a relaxed and easy feel. Designed with a low-profile back neck tape. Made from 100% polyester. Machine washable. Not intended for use as Personal Protective Equipment (PPE).
