Diadem Premier Tennis Balls

No, these are specifically engineered for hard court surfaces. While they will still bounce on clay, the extra-duty felt is optimized for the abrasive nature of hard courts and may pick up too much clay or play differently than a dedicated clay court ball.

Extra duty felt is thicker and more durable than regular duty felt. It is designed to resist the wear and tear caused by hard court surfaces, helping the ball maintain its fluff and bounce characteristics for a longer period during intense play.

Yes, these balls are sanctioned and approved by both the ITF and USTA. They meet the strict performance standards required for sanctioned competitive matches.

Each pressurized can contains three tennis balls.

Like all pressurized balls, they are designed to be used immediately after opening. While the pressurized can keeps them fresh until the seal is broken, the internal pressure will begin to dissipate once exposed to the air, so you should expect peak performance during your first match or practice session.
