Product Details

Mizuno's JPX921 irons are built for results. Practical tools engineered with one intention - to improve your on-course performance. Whether you need the explosive ball speeds of Hot Metal and Hot Metal Pro, the precision of their Tour model or the ultimate balance of the new Forged with Chromoly – the JPX921 series has you covered. 

“Applying the potential of Chromoly means that the JPX921 irons hold their own in any simulator test – without having to crank #7 iron lofts at all cost. Look, feel, launch, spin and landing angles have to be right through the set. Ultimately what sets Mizuno irons apart.”

David Llewellyn / Director of R&D

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.

"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."

Chris Voshall / Product Manager, Mizuno


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. 

Additional Hot Metal ‘Pro’ Version:  More compact option with reduced offset.

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.
