The Nike® Swift Dri-FIT Short Sleeve Running Top has been designed to help reduce chafing and improve breathability. It's soft and sweat-wicking so you can focus on your miles, and nothing else. Modified raglan sleeves with the optimal length are designed to help reduce underarm chafing and allow for a wider range of motion. Nike Dri-FIT technology moves sweat away from your skin for quicker evaporation, helping you stay dry and comfortable. It combines with a large mesh panel on the back that helps moisture escape. The top is tapered around the waist so that layering with other pieces is easier. Plus, a curved hem helps keep you covered through your stride.
