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 utilise the resilience of Chromoly - the JPX921 has the most complex face geometry to date for additional energy from the clubface. Choose the Pro version for a more compact profile with reduced offset.

Full Body Chromoly Forged Iron: The 3rd generation of designing and manufacturing irons using Chromoly – is now taken to its limits. A re-engineered CORTEC 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. 

Shaft: True Temper Project X LZ Blackout Steel. Flex 5.5. Weight 115g.
