The new JPX-s is a soft compression edition of Mizuno’s three-piece golf ball, producing a balanced performance for a wider range of swing speeds. Mizuno’s engineers discovered that softening the core not only improved the feel of the JPX-s at impact, but also increased initial ball speed for the majority of players.

An enhanced version of Mizuno’s Dimple-Cluster design improves the JPX-s aerodynamics, converting miles per hour into distance. With 54 extra micro dimples (566 dimples in total), the new JPX-s has an increased ability to maintain its flight for longer – the micro dimples taking effect at lower ball speeds. The uniquely aerodynamic cover design was conceived and tested in Mizuno’s own air tunnel.

“We call this Balanced Performance, as every measurable performance aspect of the JPX-s has evolved without sacrifice of another – speed, feel, spin, aerodynamics and durability,” said Tetsuya Kanayama, director of Mizuno R&D.

Testing with slightly higher swing speeds also showed some unexpected results. Nobuhito Sato from the Japan Golf Tour carried the JPX-s about 233 metres – on average 16 metres longer than his normal tour ball / MP-s with the driver. A recent Golf Digest report suggested that only players with handicaps of five or lower averaged a total driving distance of more than 230 metres, with the overall average at just 200.76 metres.

“Although Sato isn’t a long hitter by tour standards – his driver clubhead speed of 102mph is comfortably more than most amateurs,” observed Alex Thorne, European Tour operations manager, “proving that this softer compression is going to produce greater yardage for the majority of players.”


Features and benefits:

Balanced Performance: Speed, feel, aerodynamics and durability enhanced together.

Softer compression: Creates greater ball speed for the majority of amateur swings.

566 Micro Dimple Design: Increased hang time past the apex of ball flight.
