Lightweight and well adapted for running, training or yoga, the Nike Challenger men's 2-in-1 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 increased support and range of motion. These shorts also provide storage thanks to the side seams pockets and the hook-and-loop closure back pocket so you can keep your essentials secure and close at hand.
