Essential for beginners and elites, the Nike Dri-FIT Miler Cool Men's Short-Sleeve Running Top is a sleek crew-neck shirt for any mileage. Fast drying and lightweight, the top keeps you comfortable, even as you transition from your run to your everyday hustle. Stay Dry The soft fabric has Dri-FIT Technology that helps keep you dry and comfortable by pulling sweat away from your skin to the fabric's surface, where it quickly evaporates. Stay Cool Mesh fabric throughout the top helps body heat escape so you can stay cool. The mesh on the shoulder panels has a more open construction for enhanced cooling. Stay Moving Flat seams provide a smooth feel on your skin as you run. The shoulder seams are shifted closer to the collar bones for more comfort, especially if you' re wearing a backpack for miles.
