URBAN RUNNING. The Nike Run Icon Clash Top keeps you cool mile after mile. Designed for an active lifestyle, the top's design and graphics are inspired by those who make the city their terrain. This season's Icon Clash collection is all about the urban playground. The top in eye-catching colors features a zebra-print Swoosh at the center front. The knit material with Dri-FIT technology is always dry and comfortable against the skin. Mesh at the shoulders and upper back ensures better ventilation. The specially shaped hem at the front and back provides additional protection.
