The Nike Dri-FIT Challenger Run Division men's running shorts are made of woven polyester for a smooth feel any time of the day. The Dri-FIT technology wicks sweat away to keep you dry and comfortable from start to finish while the internal brief liner is articulated for optimal support and comfort. These shorts also provide storage thanks to the side seams pockets and the snap back pocket so you can keep your essentials secure and close at hand.
