Penn ProPenn Marathon

The ProPenn Marathon uses 'Encore' core technology, which is engineered to retain its bounce and structural integrity for 22% longer than standard tennis balls. This allows the ball to maintain consistent performance even after extended rallies.

LongPlay felt is designed specifically for durability and visibility. It resists fluffing and wearing down as quickly as standard felt, which helps the ball maintain its flight characteristics and makes it easier to track on the court over time.

Yes, these are versatile balls designed to perform consistently on all court surfaces, including hard courts, clay, and grass. Their durable construction is particularly beneficial for abrasive hard court surfaces where balls typically wear out faster.

Being the official ball of the Professional Tennis Registry (PTR) means these balls meet high standards for consistency and playability. For a recreational player, this translates to a reliable, predictable bounce and flight path that doesn't change drastically mid-match.

They are designed to feel standard in terms of weight and compression. While they are built for longevity, they do not sacrifice the playability or 'feel' that most players expect from a high-quality match ball.
