The JPX925 Hot Metal Pro redefines the performance of an already industry-leading franchise. Combining the power and speed of Nickel Chromoly with a newly engineered CORTECH Design featuring a Contour Ellipse face, the consistency of distance across the entire impact zone has never been as long and predictable. The addition of tungsten weighting low in the head adds a height and landing angle element that makes hitting precise shots into greens easier than ever. Designed for golfers seeking a more compact profile, the Hot Metal Pro offers the same advanced technology in a sleeker, more refined package.
