Pro Penn Marathon+ is the upgraded version of Penn's longest-lasting tennis ball — extra duty felt, in a four-pack.
The Marathon line is built around Encore™ technology, which keeps pressure and bounce alive for longer than a standard ball. The '+' adds a further step up in durability and feel. Extra duty felt is what you want on hard courts: it resists abrasion instead of fluffing up and slowing down after a few games.
