Wilson Championship Tennis Ball

These balls are specifically engineered for hard court surfaces. While they will technically bounce on other surfaces, the Extra Duty felt is designed to resist the abrasive nature of hard courts, so they may feel overly fuzzy or heavy if used on clay or grass.

Extra Duty refers to the specific type of felt used on the ball's exterior. It is a thicker, more durable weave designed to withstand the high friction and abrasive texture of hard court surfaces, helping the ball maintain its bounce and playability for longer periods.

Yes, these balls are ITF and USTA sanctioned. They meet the official standards required for tournament play, ensuring consistent bounce and performance characteristics.

Like all pressurized tennis balls, they will begin to lose their internal pressure as soon as the seal is broken. You can expect optimal performance for one to two matches, after which you will notice a gradual decline in bounce and responsiveness.

This 72-ball case is ideal if you play multiple times a week or run a practice group. If you play only occasionally, keep in mind that pressurized balls have a shelf life even when unopened, so ensure you can use them within a reasonable timeframe to avoid the pressure dissipating while they sit in storage.
