HEAD Pro Penn Marathon Regular Duty Tennis Balls (Case)

Pro Penn Marathon in regular duty felt, by the case — Penn's longest-lasting tennis ball, in the version meant for softer courts.

Regular duty felt is woven less densely than extra duty. On clay or indoor carpet that is exactly right: the ball picks up less court material, stays lighter and plays truer. On an outdoor hard court it will wear out quickly, so match the felt to the surface you actually play on. Encore™ technology keeps the pressure and bounce going longer than a standard ball either way.

Who it's for

• Clay and indoor players, and clubs buying in volume
• Regular duty felt — the right choice for softer surfaces
• Encore™ technology for longer-lasting bounce and pressure
