Pro Penn Marathon (Regular Duty) Tennis Balls (12 Cans):
As the name suggests, this tennis ball is designed to last longer than most. It feels bad chucking one-match used balls (I give them to pupp-ay or toss ’em in a practice hopper) but that’s been a fact of tennis life. Penn’s newest tennis ball, the Pro Penn Marathon, not only offers greater longevity than past Penn balls but also better durability and visibility. Encore Technology is the core compound that maximizes longer-lasting playing properties. By using a proprietary blend of natural and man-made polymers, ball softening is limited. The core stays fresher longer, playing fresh from the can longer. Pro Penn Marathon has a 22% longer lasting core compared to Penn’s original Pro Penn+ tennis ball (and those have actually been among the best for hopper ball longevity according to a few teaching pros we’ve spoken with).
Pro Penn XD BallLongPlay felt combines wool and high tenacity fibers for durability and Smart Optik treatment keeps the balls cleaner and brighter looking throughout play as they don’t pick up dirt as readily.
