Mizuno JPX-S Golf Balls

Mizuno reveals new airtime concept with JPX ball with dimple-cluster design for delayed descent.

The new JPX-S is a soft compression edition of Mizuno’s 3 piece ball – producing a balanced performance for a wider range of swing speeds. Mizuno’s engineers discovered that a softening of the core not only improved the feel of the JPX-S at impact, but also increased initial ball speed for the majority of players.

The ‘Dimple-Cluster’ design of the new JPX is a result of a 3 year study into the descent phase of ball flight.

In tandem with the Fukuoka Institute of Technology, Mizuno’s ball engineers found that by focusing on dimple performance in the ‘descent phase’, they could effectively extend airtime and overall distance. The smaller, micro-dimples within the JPX’s cluster pattern take effect at slower speeds – as the ball transitions to descent.

With the added dimension of descent performance – the JPX delivers increased yardage in a soft, responsive package.

“The Dimple-Clusters have little effect at higher ball speeds generated at impact. However as the ball peaks and slows, they start to take full effect. By stalling the descent phase just a fraction, we were able to increase the JPX’s overall airtime.” Masashi Tamakoshi – Head of Golf Ball Development.
