Mizuno JPX 850 Driver: Packed with Mizuno’s Cutting Edge Technology

Mizuno is bringing their entire chart topping iron technology into the driver market. The JPX 850 driver is an elite, top-notch driver that is loaded with advanced technology. This has all the best innovations packed into one design. On top of the design the looks and color make this a flawless driver. The crown has a piercing blue color that flows into the black ion plated finish on the sole. Enough about looks, let’s get into the technology.

The Mizuno JPX 850 driver features a Rebound Crown which goes from the top of the crown to the sole, creating a rebound and trampoline-like effect off the face for explosive distance.

The JPX 850 driver has two removable, eight gram tungsten weights that can be moved and positioned in the central fast track sliding rail, or the two lateral slots. The fast track allows for 10 different flight settings, 4 neutral, 3 draw, or 3 fade. sliding rail will dial in the spin rate. Testing on Trackman showed there to be a difference of up to 300 rpm of spin depending upon the position in the fast track center rail. The lateral weight slots allow you to alter the shot shape to a draw or fade bias. Testing on Trackman accounted for roughly 20 yards of discrepancy when the weights were placed in the two extreme positions of the lateral slots.

“The genius of the new Fast Track is that it adds the dimension of launch angle and spin rate. Now the player is truly in control of maximizing all aspects of their ball flight off the tee.” Chuck Couch, VP of Product Management

To take adjustability to the next level the Mizuno JPX 850 driver has a Quick Switch shaft release system. This system allows for eight different loft settings, 7.5 – 11.5 degrees. The driver will is available in one head design (430cc) with one loft, 9.5 degrees. The driver will have the Fujikura Motore Speeder shaft as a stock shaft, not an in-house design. However, there are other shafts available through custom options.


The Mizuno JPX 850 fairway wood is a direct extension of the JPX 850 driver. It’s all about distance and maintaining workability.

The Shock Wave sole allows the entire head of the golf club to flex at impact, transferring all the energy back to the golf ball for increased ball speeds and maximum distance.

“The Shock Wave sole enables the entire head to flex – delivering an additional source of energy to the golf ball. It’s hugely improved way to increase ball speeds for un-matched distance.” David Llewellyn, Golf Club R&D Manager

The JPX 850 fairway wood has a strategically placed weight for a low CG. This low CG will increase the sweet area and produce easy launching shots from all course conditions.

The JPX 850 fairway wood features the quick switch adjustability that can also be found in the JPX 850 driver. This allows the golf club a total of four degrees of adjustability. The fairway wood is available in a 3 (15 degrees), 5 (18 degrees), and 7 (21 degrees). The fairway wood will have the Fujikura Motore Speeder shaft as a stock shaft. However, there are other shafts available through custom options.


The Mizuno JPX 850 hybrid features all the same great technology as the JPX 850 fairway wood, except for the quick switch adjustability. Even though it doesn’t have the adjustability, it’s available in multiple lofts sure to find a fit into any player’s bag.

“Hybrids have always played an important part in my set make-up. With this new JPX-850 hybrid, I have seen a noticeable improvement in distance control and ease of ball flight” Stacy Lewis, LPGA Professional

It’s available in a 2 (16 degrees), 3 (19 degrees), 4 (22 degrees), and  (25 degrees). The hybrid will have the Fujikura Motore Speeder shaft as a stock shaft. However, there are other shafts available through custom options.
