The Spalding NBA Zio Indoor/Outdoor Composite 29.5 Mens Basketball is designed with a durable composite cover for indoor and outdoor use.

Built using a Zi/O composite leather cover, the Spalding official-size NBA Zi/O basketball looks and feels like an official NBA ball. The ball also includes a foam-backed design with full ball pebbling, helping it stand up to the challenge of competitive play while maintaining a soft, tacky feel. Best of all, the ball is designed for use both indoor and outdoor use, so you can bring it to the YMCA or the playground. Designed to meet all of the NBA's stringent ball specifications, the Zi/O ball measures 29.5 inches and comes in an official NBA ball weight.
