Penn Pro Marathon Tennis Balls

The Pro Marathon is built for longevity. It features Penn's exclusive Encore™ technology, which creates a core that is 22% more durable than standard options, allowing the ball to retain its bounce and pressure through much longer practice sessions.

While these are specifically engineered for softer surfaces like clay, grass, and carpet, Penn does offer an extra-duty felt version of this ball designed specifically for hard courts. Be sure to select the extra-duty option if you play exclusively on abrasive hard surfaces.

Yes, the LongPlay® high-tenacity felt is designed to resist fluffing and wear over time. This helps the ball maintain its aerodynamic properties and visibility for a longer period, so you don't have to swap out balls as frequently during a match.

This case contains 24 cans, with 3 balls per can, totaling 72 tennis balls. It is an ideal bulk purchase for clubs, coaches, or frequent players who go through equipment quickly.

These are pressurized tennis balls. This design provides the lively, responsive bounce expected for competitive play, though it means they will eventually lose pressure over time compared to pressureless alternatives.
