Chromoloy3

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.

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

Extreme perimeter weighting with toe bias for stability from off center strikes.

'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.'
