Our test team casts its eye over the brand's latest model in its Mizuno JPX850 driver review

Product Overview

Mizuno JPX850 driver


  • We have seen so many drivers since Mizuno first offered Fast Track sliding weight adjustability in 2007’s MP-600 model. This new adjustable offering is completely different, and brings Mizuno drivers into the present and beyond.
  • The piercing blue crown on the new JPX850 looks beautiful behind the ball, and the performance it helps to provide is equally impressive. The 440cc head didn’t result in a drop-off in forgiveness for us, as might have been expected, and the adjustability made a particularly big difference to the amount of spin on offer.
  • An expert custom-fitter will be able to make alterations that noticeably change the performance of the driver to help find the ideal set-up for a wide range of golfers. This is undoubtedly the best driver offering from Mizuno in a very long time.


  • Even though the smaller head didn’t affect performance, some will still prefer the look of a larger head behind the ball. The adjustability on offer is a little more complicated than others on the market, while the blue crown will divide opinion.

Golf Monthly’s Mizuno JPX850 driver review:

Key technology:

The Fast Track weight system first seen in 2007 makes a return in the Mizuno JPX850 driver. It features two twin eight-gram weights that can be located on either a central sliding rail, or on slots in the heel and toe.

This allows for 10 settings, which can vary lateral trajectory and, for the first time, spin rates and launch angles. The face and crown are engineered to increase ball speeds.

Will suit… players after a great-looking head with plenty of adjustability on offer.

The JPX850 is also one of our top 10 best drivers for 2015
