Mizuno JPX-850 4-PW, GW Iron Set with Steel Shafts
Power up with the longest iron in golf! The breakthroughs in distance and ball speed of the Mizuno JPX-850 Iron are achieved through Mizuno's Power Frame design, which greatly increases the rebound area of the club face. In addition, the Power Frame positions weight in the extreme corners of the club head to increase stability on off-center shots, maximizing forgiveness and consistent distance.
Equally is important, so the innovative Power Frame design ensures ball speeds are consistently high across the entire club face and that the high COR is not created at the expense of feel or control. The JPX-850 delivers more distance with more solid feel than any other iron.
"Simply increasing ball speed is not our goal. Making it happen within a manageable head size is the real challenge. With the Power Frame we were able to take ball speeds to a completely different level, all while keeping it hand-in-hand with a nice feel and a level of workability."
