This week we’re testing another set of 2025 irons with the Mizuno JPX925 Irons making their way to the Three Swing Challenge!
The Mizuno JPX 925 Forged irons offer golfers a harmonious blend of distance, control, and the signature Mizuno feel. Central to their design is the CORTECH technology with a Contour Ellipse Face, which optimizes ball speed across the clubface, ensuring consistent performance even on off-center hits.
The irons feature a multi-material construction: the longer irons (4-7) are forged from Chromoly 4120, providing strength and flexibility for enhanced speed and adjustability, while the shorter irons (8-GW) utilize 1025E Pure Select Mild Carbon Steel, delivering precision and a soft feel. The Triple Cut Sole design enhances turf interaction, offering versatility across various lies and conditions.
