Pro Penn Marathon Extra Duty Tennis Balls

Pro Penn Marathon Extra Duty Tennis Balls are Penn’s longest lasting premium balls, built for players who want top level consistency and durability on outdoor hard courts.

With Encore core technology, high tenacity LongPlay felt and Smart Optik visibility treatment, they hold pressure longer, stay cleaner and remain easy to see under sun or lights during long matches and heavy ball machine sessions.

• Penn’s longest lasting ball featuring Encore technology in the core so the ball keeps its liveliness and does not soften as quickly over time.
• LongPlay premium felt uses a high tenacity construction that resists wear and stays cleaner, picking up less dirt and dust on gritty hard courts.
• Smart Optik visibility treated felt offers brighter, higher contrast color so it is easier to track the ball against court and background.
• Extra duty construction optimized for hard court surfaces like acrylic and concrete where durability and consistent bounce are critical.
• USTA and ITF approved so the same ball you train with is eligible for sanctioned league and tournament play.
• Preferred by teaching pros and clubs for its combination of longevity, visibility and performance in high volume use.
• Three balls per can ideal for match play, practice sets and ball machine work when you need a durable, high quality option.
