The Tracksuit Jacket is part of the Heritage collection. Perfect for wearing both before and after playing sports, but also ideal during a competitive match on the court thanks to a comfortable tennis look & feel. Features a zipper closure and upright collar. The Heritage collection goes back to basics. The classic three-color combination refers to the origin of the brand and tennis tradition in the United States. The K-Swiss logo also features the signature Brunner Blue color, named after the founders of K-Swiss, brothers Art and Ernie Brunner, and corresponds to the legendary color blue of most competitive tennis court surfaces in the United States.
