The Brooks Carbonite 4” shorts allow you to stay cool in warm weather and shine after dark. Brooks has included 3M™ Scotchlite™ Carbon Black Stretch reflectivity in critical motion zones, which helps drivers recognize you as a runner in motion up to 600 feet away. Brooks updated the jersey brief liner to make sure it stays put when you pick up the pace, while keeping a soft, sweat-wicking material for maximum comfort. These high-rise shorts are semi-fitted with an infinity drawcord that delivers a comfortable fit that moves with you on the run. These shorts include convenient storage with two drop-in liner pockets and a hidden zip pocket to keep items secure. These shorts also include a key loop to attach your key.
