Mizuno JPX ONE Custom Driver

The JPX ONE Driver, the world’s first to feature NANOALLOY™ face technology. Developed in collaboration with materials specialists Toray, NANOALLOY™ utilizes microscopic polymer dispersion to produce a face that dynamically alters its elasticity under impact. The result is a material that stores and releases more energy at impact than traditional titanium or composite constructions, delivering unprecedented ball speeds across a wider area of the face. This breakthrough pairs with a newly engineered CORTECH Face, up to 0.35mm thinner than previous generations, expanding the CORAREA (high-speed rebound zone) by over 15%. In robotic testing, JPX ONE outperformed leading competitors for both ball speed and carry, producing faster, longer, and more consistent results from every impact location. Two models, JPX ONE and JPX ONE SELECT, offer distinct performance profiles. JPX ONE features a slightly larger footprint for higher stability and straighter ball flight, while JPX ONE SELECT delivers a more compact, tour-preferred shape with a neutral-to-fade bias.
