Athletes can wear this Nike Dri-FIT Men's Long-Sleeve 1/2-Zip Pullover to build up heat before the big game, retain body warmth on an early-morning training run or stay comfortable while kicking back with teammates. The Dri-FIT Max fabric wicks sweat away from the body and helps it evaporate, so competitors won't feel weighed down. Half-zip neckline lets wearers regulate their body temperature and customize the look of the shirt. Interior taping prevents the center front zipper from irritating and rubbing against athletes' skin. 100% polyester. Trademark Swoosh on right chest, opposite the Brother Rice Warrior head which is over the heart, of course.
