The�Mizuno JPX925 Hot Metal Combo Set�is designed for players who struggle to produce the launch and spin required for successful long iron play. Replacing long irons with faster, higher-launching, more forgiving hybrids increases carry distances, produces steeper, green-holding descent angles, and creates ideal gapping between stronger lofted clubs. For the first time, Mizuno introduces a multi-material construction to the Hot Metal Iron lineup, adding tungsten weighting to the already highly potent Nickel Chromoly construction. Strategically positioning weight lower in the head increases stability while producing a higher launch and steeper, green-holding landing angles. Consequently, JPX925 is remarkably precise, a rare and unique trait for such powerful, distance-focused irons. The latest Hot Metal Irons also benefit tremendously from a new, completely re-engineered Contour Ellipse Face. Now up to an astonishing 30% thinner than the previous generation, this multi-thickness face profile enhances ball speed on center strikes and maximizes speed retention across the entire hitting surface, ensuring consistently longer shots and more predictable results. The standard Hot Metal, a game-improvement iron, is an excellent option for players seeking super speed and all-around forgiveness. In terms of forgiveness and size, it falls between the Pro and the HL.
