The JPX921 Hot Metal irons pair Mizuno's fastest ever ball speeds with a piercingly straight ball-flight and controllable landing angles.
The 3rd generation of Mizuno irons to utilize the resilience of Chromoly - the JPX921 has the most complex face geometry to date for additional energy from the clubface. Choose the more Pro version for a more compact profile with reduced offset.
Available as Hot Metal and Hot Metal Pro. The Hot Metal Irons have a slightly larger profile and offset than the Hot Metal Pro, reducing slices and maximising forgiveness.
”The introduction of Chromoly was the breakthrough Mizuno needed to take a step up in ball speed. We learn more about the potential of Chromoly with each generation and push it further each time.”
- Mizuno, 2020
FASTER AND FASTER CHROMOLY 4140M Our 3rd generation of designing and manufacturing irons using Chromoly : now taken to its limits. A re-engineered CORTECH face, is now 0.2mm thinner across the centre point.
SEAMLESS CUP FACE A new variable thickness sole design allows the leading edge to act as a hinge, resulting in greater face flex and ball speeds.
HARMONIC IMPACT Predicting vibration patterns dictated 3 additional sound ribs : producing a more solid sensation.
PEARL BRUSH FINISH Anti-glare to minimise distractions over the ball.
STABILITY FRAME Extreme perimeter weighting with toe bias for stability from off centre strikes.
