Penn Pro Marathon
The 2026 Penn Pro Marathon All-Court (Regular Duty) is designed for softer surfaces like clay, grass, or indoor carpet. It shares the same Encore™ Core as the Extra Duty version but uses a thinner, more tightly woven felt. This 'Regular Duty' felt is engineered to remain compact, preventing the ball from picking up too much moisture or clay dust, which would make it sluggish. On indoor hard courts, this version plays significantly faster and 'zippier' than the Extra Duty variant. In 2026, it is the preferred choice for indoor league play where players want a ball that cuts through the air with less drag. However, use on outdoor hard courts is not recommended, as the thinner felt will shred in less than 90 minutes of play.

Frequently Asked Questions
What's the difference between Pro Marathon Extra Duty and Regular Duty?
The Regular Duty version uses thinner, more tightly woven felt designed for softer surfaces like clay, grass, or indoor carpet, while Extra Duty is for hard courts.
Can I use Regular Duty on outdoor hard courts?
Not recommended. The thinner felt will shred in less than 90 minutes of play on abrasive hard court surfaces.
Why does this version play faster than Extra Duty?
The thinner felt creates less aerodynamic drag, allowing the ball to cut through the air with more speed, making it ideal for indoor league play.
Does it share the same Encore™ Core as Extra Duty?
Yes, both versions use the same Encore™ Core technology, but the Regular Duty felt is engineered to remain compact and prevent moisture pickup on clay courts.
