Unlock your potential for maximum ball speed and extraordinary height. The Mizuno JPX 925 Hot Metal High Launch (HL) ladies irons are engineered with a lower, deeper centre of gravity and softer lofts — designed to improve launch and increase trajectory, making them the ideal choice for lady golfers seeking a better attack angle to optimise their game. For the first time ever, the Hot Metal family introduces multi-material construction, combining the proven speed of Nickel Chromoly with strategically placed tungsten weighting to deliver higher launch and steeper landing angles — a level of precision rarely found in distance-focused designs.
The fifth generation of Mizuno's Chromoly CORTECH platform has been completely re-engineered around a brand-new Contour Ellipse face. At just 1.2 mm thick, the multi-thickness face profile is up to 30% thinner than the JPX 923 generation. Its unique elliptical contour — running from the high toe to the low heel — is tuned to retain maximum ball speed on off-centre strikes where speed is typically lost most. The result is a dramatically larger effective hitting zone and more consistent distance across every shot.
The innovative one-piece Cup Face construction features strategically thinned areas that revolve 360 degrees around the entire perimeter of the face. This engineering approach not only expands the CORAREA significantly but also ensures maximum ball speed is delivered across a much larger portion of the face. Whether you catch the ball on the toe, heel, or low on the face, the Seamless Cup Face preserves pace where traditional face designs would typically see speed drop off dramatically.
For the first time in the Hot Metal family, Mizuno has introduced multi-material construction to the JPX 925. Nickel-tungsten weights are precisely positioned low in the 4–7 irons, lowering the centre of gravity and generating a higher launch with a lower effective sweet spot. This produces steeper, green-holding landing angles that make approaching pins with long irons easier than ever — a crucial advantage for lady golfers with moderate swing speeds seeking to hold greens from distance.
The Variable Sole Thickness design allows the sole of the iron to flex more efficiently through impact. By removing constraints imposed by the tungsten weighting in the sole, this feature expands the total face flex area to increase the overall CORAREA. More face flex translates directly into higher ball speeds across a broader area of the face, boosting both distance and forgiveness — especially beneficial for shots caught slightly low on the face.
The Balance Stability Frame redistributes mass intelligently around the cavity to improve both control and off-centre forgiveness simultaneously. By balancing weight placement precisely, Mizuno engineers achieve a moment of inertia that maintains ball speed and directional integrity even on mishits. The frame geometry is designed to produce the vibration signature and sound character preferred by tour professionals — delivering a uniquely satisfying, solid-but-hot impact feel that inspires confidence at every level of play.
Mizuno's Harmonic Impact Technology enhances feel through meticulously tuned head geometry combined with acoustic Sound Ribs that reinforce the topline. These ribs are engineered to create precise vibration patterns for a solid, explosive impact sound without harshness. An innovative Sound Bar on the rear of the cavity further refines the acoustic feedback by attenuating unwanted frequencies at impact — the result is a uniquely satisfying sensation that clearly communicates the quality of each strike.
