Product Details The JPX800HD harnesses the power of the original JPX800 iron, in a high launching, super forgiving clubhead. The ball speeds of the JPX800 line are taken to a new level in this fuel injected edition - with a high energy pocket cavity from 4 to 7 iron. The pocket cavity allows a thinner sole portion, which in turn encourages the clubface to flex. From 8-PW the JPX800HD features a more solid design with an emphasis on control. A wide sole featuring Mizuno's new C-Grind, increased off set and thicker top line combine to create an easy, high ball flight. Following Mizuno's 'Balanced Performance' concept, the JPX800HD tapers down in size from the longer irons - to a workable mid-size pitching wedge. A solid feel is factored into the design, with sound patterns engineered through Mizuno's Harmonic Impact Technology project.
