Midnight CortgliaSport Checkered Messenger Tennis Bag. Designed with fashion and function in mind, CortigliaSport offers an affordable designer tennis bag. CortigliaSport tennis bags are designed to fit two racquets, with a large exterior pocket and a roomy interior. Fitted with one large strap, this contemporary tennis bag is designed to be worn like a modern messenger bag, across one's chest, or over the shoulder. Our newly designed line is made of both beautiful leather and sporty nylon. Solid metal feet protect the base of the bag both on the court and at the club.
