Mizuno JPX-800 Irons

The Mizuno JPX-800 Irons are a big jump into the game improvement category for Mizuno Golf. Sure- they have other irons in this space (MX-1000, MX-300) but most people know and respect Mizuno most for their game-enhancing line of muscle back and blade irons known for their amazing feel and precision. In my opinion there was a big gap between the MX-1000's and the MP lines of clubs and the Mizuno JPX-800 Irons a full-fledged jump into that space, providing 8 to 24 handicappers with a truly remarkable option; a club with the feel Mizuno is known for combined with the game improvement qualities desired by many of us like forgiveness and increased distance. I don't want to ruin the rest of my review- but mission (mostly) accomplished!

A serious looking iron with 'Balanced Performance' the Mizuno JPX-800 Irons are Mizuno's first to bring its JPX exotic technology platform to Europe

'Balanced Performance' is the result of a project to create an iron with strengths in a number of key criteria (feel, control, forgiveness, distance, profile) without one compromising another. The Mizuno JPX-800 Irons deliver the magical combination of being Mizuno's most forgiving (MOI measurement) and longest (COR measurement) iron of all time.

 The JPX800's look from address and solidity at impact will have single figure players questioning their choice of iron.

The visible distance gains of the Mizuno JPX-800 Irons are achieved by combining Mizuno's HOT METAL approach - incorporating a new manufacturing process for a thinner, more uniform iron face. This HOT METAL process allows the Mizuno JPX-800 Irons to hit the maximum allowable limits for energy transfer, far exceeding previous Mizuno irons.

An exotic pocket cavity, with multiple thickness levels and an external power bar add the highest measurable levels of forgiveness (MOI) achieved in a Mizuno iron to date.

The Mizuno JPX-800 Irons achieve all this within a mid-size head which presents itself even more compactly and versatile thanks to a triple cut sole design. A progressive flow to shapely shorter irons, complete the JPX800s 'Balanced' orientation.

"The Mizuno JPX-800 Irons is an incredible iron that's hard to pigeonhole. To achieve these ball speeds and MOI numbers, you’d expect to compromise by adding lots of offset, or thick top and bottom edges. 

But our design challenge was to pack all this performance into a head shape that a tour player wouldn't reject. It's much easier to create an iron just to either feel great, or be very forgiving, or extremely long - 'Balanced Performance' is much more a challenge" - David Llewellyn, R&D

JPX-800 irons Are Launched

How do you improve on one of the more popular game improvement lines of the past few years? If you're Mizuno, you don't - instead, you pull all the great ideas and technology from your assets around the world, and build something new.

Mizuno has always made very good game improvement irons, but we’ve mostly been recognized for our MP line of game enhancement products. JPX is by far Mizuno’s strongest global commitment to the game improvement category, and we took dead aim at our competitors to beat them in every category of game improvement performance, especially distance and forgiveness. The Mizuno JPX-800 Irons is truly an incredible iron, and players are going to be blown away by the distance gains they’ll experience versus whatever iron they are currently playing.

The incredulous look on Ryder Cup star Luke Donald's face when he first hit the latest Mizuno JPX-800 irons spoke volumes for its impact on the World's No.8 golfer.

As Mizuno's leading-ranked staff player, he had been lined up to give his endorsement to the MP-63 irons he plans to play on Tour later in the year but during a break in filming a test session, Donald also grabbed hold of a 6-iron from a set of Mizuno JPX-800 Irons, the clubs aimed at the improving club golfer.
"Wow!" he said as he smacked shot after shot down the range. 
A check on his ball speed, I was told at the media launch of these Mizuno JPX-800 Irons at Bearwood Lakes recently, revealed an increase of nearly 10mph off the face of the JPX-800 and an increase of nearly 20 yards in distance compared to the new MP-63. The carry of the Mizuno JPX-800 Irons 6-iron in Donald's hands was measured at 193.3 yards, compared to 175.9 for the MP-63 and a ball speed of 135.6mph (126.5 mph).

But while distance per Mizuno JPX-800 Irons is probably the major requirement of the club golfer, for the precision demanded by Donald, known for his iron accuracy on Tour, he would have to sacrifice a certain amount of workability, meaning that the new MP-63 will be more suited to him.

JPX-800 Irons Review

The Mizuno JPX-800 Irons deliver unbelievable distance and forgiveness in our longest game-improvement iron. We combined our innovative Max COR technology, an ultrathin Hot Metal face and an exotic pocket cavity to provide the extra yards you've been searching for. You're going to be at least a club longer."
—Chris Voshall, R&D engineer, Mizuno USA Golf

"With the perfect balance of forgiveness, distance and feel, the Mizuno JPX-800 Irons Pro features the highest COR ever in a Mizuno one-piece Grain Flow Forged iron. A large cavity is created using a CNC milling process that thins the face to raise ball speeds for maximum distance and optimizes a low, deep center of gravity for increased forgiveness."
