JPX Tour reigns supreme as Mizunos most played iron model in professional golf. The JPX 923 Tour still features a one-piece Grain Flow Forged body, now with a copper underlay to improve sound and feel at impact. A new V-Chassis design produces a narrower top line and sole, as well as a more rounded trailing edge to create a cleaner turf interaction. Shorter blade lengths and a more compact design from the 6 iron to the GW gives you precision where its most needed. The non-reflective, Chrome plated finishing reduces bright sun glare.
