Mizuno JPX 850 Forged Irons 4 - PW
Introducing BORON Forged
After 6 years of development – the introduction of Boron to Mizuno’s Grain Flow Forging process enables the JPX850 to overcome the distance limitations of traditional forged irons.
30% stronger than its traditional 1025E steel billets – allowing for a thinner face and extreme ball speeds.
The thinner Boron face is strategically reinforced by a Power Frame cavity that enables the entire face to flex for increased ball speeds.
A shorter top edge frame controls vibration for the recognisably solid Mizuno feel.
