Engineered for lasting performance and unwavering consistency on hard courts, the Pro Penn Marathon+ XD is built to endure demanding match play and high-intensity training sessions.

True to Penn’s legacy as “The Heartbeat of the Game,” Marathon+ combines advanced technologies designed to maintain consistent performance from the first serve to the final point.

Technologies

TrueBounce

Penn’s new technology is our next-generation natural-rubber compound engineered for the most reliable performance on every point.

Encore+

Encore+ is built to maximize durability by helping the core hold its structure, pressure, and response over time. The PPM+ ball is designed to reduce performance drop-off and extend play, so it keeps delivering reliable bounce and predictable feel longer, even through frequent and extended use.

LongPlay+

LongPlay+ is an engineered woven felt designed to last longer and resist wear over time. The result is a ball that keeps its feel and response more consistently, so players experience reliable performance session after session.

Smart Optik 360

Smart Optik 360 is designed to improve how clearly and early players see the ball, using a brighter, more visible felt that stands out from every angle. By enhancing visual perception and recognition, it helps players track the ball sooner, anticipate its trajectory, and prepare their shots with greater confidence and timing.

Sustainability

Designed for recycling. Built for faster biodegradation.

Penn’s new sustainable technology brings together two complementary sustainability actions: a fully recyclable can design and accelerated biodegradation powered by the Penn BioForge organic additive. Whether it is recycled or sent to landfill, it remains the most sustainable can in tennis.

Sustainability engineered from start to finish.
