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.

Harmonic Impact Technology: Fine tuned head geometry delivers ideal impact feel and feedback
Seamless Cup Face: Thinned areas revolving 360 degrees around the perimeter increase rebound area for maximum ball speed across the entire face
CORTECH Design: Optimized face thickness distribution to maximize COR AREA
Variable Sole Thickness: Increase overall face flex area for add CORAREA
Acoustic Sound Ribs: Precisely dial in specific vibration patterns for a solid, explosive impact sound
