JPX 921 Hot Metal
CHROMOLOY
The JPX 921 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 JPX 921 has the most complex face geometry to date for additional energy from the clubface.
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 center 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 patters dictated 3 additional sound ribs – producing a more solid sensation.
PEARL BRUSH FINISH
Anti-glare to minimize distractions over the ball.
STABILITY FRAME
Additional perimeter weighting with toe bias for stability from off center strikes.
