The Under Armour UA M Challenger Pro Shorts are made of a very lightweight stretch fabric that guarantees unrestricted movement. Jacquard panels provide better breathability, while 4-Way Stretch technology allows movement in every direction. The material effectively wicks away sweat and dries quickly, making them ideal for sports activities. They have a non-slip waistband with a drawstring for a secure and comfortable fit and a secure zip pocket on the right side.
