The new JPX-800 driver utilizes Mizuno's new Ultimate Dynamic Stability (U.D.S.) technology for explosive distance from anywhere on the face. U.D.S. unites a forged Titanium 'Hot Metal' face, ultra-thin crown and a strategic internal weighting system to greatly increase vertical and horizontal MOI. The result: maximum ball speeds and massive distance, even outside of the sweet area. The 460cc Ti Construction features a six-piece plasma welded design, which provides an extremely solid feel and allows for precise COG placement for a high launch with low spin. Combined with an internal five-gram heel weight that helps square the face at impact, the JPX-800 driver will help you hit the ball longer and straighter than you ever have before.
