Mizuno JPX 925 Hot Metal Hi Launch Irons - Graphite Maximum Speed, Maximum Height. The Mizuno JPX 925 Hot Metal Hi Launch Irons are designed for golfers seeking exceptional speed and impressive height. With a lower, deeper center of gravity (CG) and strategically weaker lofts, these irons enhance launch conditions and optimize landing angles. Mizuno has achieved the highest Coefficient of Restitution (COR) for energy transfer, as defined by the USGA and R&A. The focus of the JPX 925 is on increased forgiveness through an expanded face surface, maximizing ball speed (CORAREA). This advancement is supported by a suite of innovative technologies, ensuring superior performance and reliability. CONTOUR ELLIPSE A reimagined multi-thickness face as thin as 1.2mm, a 30% enhancement over the JPX 923 model. The elliptical shape is angled from high toe to low heel to better address common mishit areas. Ensures maximum speed retention even on off-center hits. SEAMLESS CUP FACE Features a one-piece Cup Face design, allowing for thinner sections around the 360-degree perimeter. Increases CORAREA, ensuring maximum ball speed across the entire face. MULTI-MATERIAL CONSTRUCTION Nickel Tungsten weighting is strategically placed low in the 4-7 irons, promoting a higher launch and lowering the sweet spot – perfect for shots from the turf. Creates steeper landing angles, helping to hold more greens. VARIABLE SOLE THICKNESS Enables the face to flex more efficiently, enhancing CORAREA. Nickel Tungsten weighting is carefully positioned to avoid hindering face flex. BALANCED STABILITY FRAME Balanced weighting improves control while maintaining forgiveness. Provides a tour-preferred vibration and sound. HARMONIC IMPACT TECHNOLOGY The feel is more closely related to the sound than to the vibrations felt in the hands. Precisely engineered head geometry delivers ideal feel and feedback. Acoustic Sound Ribs along the top edge stiffen the top line and enhance feel. A Sound Bar (visible on the back of the club) reduces sound pressure, eliminating unwanted tinny or clicky frequencies.
