Mizuno JPX-923 Hot Metal Irons
Introducing Nickel Chromoly – A new material with so much additional ball speed, our
engineers switched their focus to feel and stopping power. At 35% stronger than our original
Hot Metal material, 4335 Nickel Chromoly enables a high-energy 8% thinner clubface.
Combined with Mizuno’s vibration controlling V-Chassis and deep CG design, the JPX923 Hot
Metal irons are as enjoyable and controllable as they are long.
As we get thinner and thinner on the clubface
to enhance ball speed – the next challenge
becomes sound and feel. The new V-Chassis
reinforces the clubhead in a different way – that
gives the extra performance hand in hand with
improved feedback
FASTER NICKEL CHROMOLY
New 4335 Nickel Chromoly is 35% stronger than our original
Chromoly, for an 8% thinner, high ball speed clubface.
V-CHASSIS FOR MORE SOLID FEEL
Mizuno’s new V-Chassis delivers a more solid
satisfying vibration pattern, even though the clubface is 8% thinner.
INCREASED STOPPING POWER
Seamless cup face construction delivers the deep centre of
gravity needed for a high launch and controllable landing angle.
CONSISTENT BALL SPEEDS ACROSS THE FACE
The thinnest part of the sole is extended
18% wider, creating a wider high-energy area.
