Compact,
with minimal offset for confident ball-strikers seeking maximum ball speed.
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.”
DAVID LLEWELLYN – R&D Director
Studying over 175,000 recorded Swing DNA fitting sessions with real golfers per year – Mizuno’s R&D team highlighted the need for three distinct player needs and launch patterns.
“There are so many different kinds of players looking for increased ball speed from their irons, we needed more options for them at a fitting level. The custom studios use shaft selection incredibly well to help with launch angle or slower swing speeds , but the JPX923 Hot Metal HL gives them a great new tool to work with.”
CHRIS VOSHALL - Director of Product
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.
THREE FITTING OPTIONS – HM PRO, HM AND HM HL
175,000 real golf swings recorded via Mizuno’s Swing DNA system every year highlighted the need for variable launch options.
