Pros: Classy, satin-like finish. Fantastic forged feel. Scoring irons are have thinner toplines than previous JPX series. Excellent forgiveness for their size and better-than-average playability. Versatile triple-cut sole design.

Cons: Not a distance iron. Long irons do not have ground-breaking forgiveness. Completely usable by better players (those who have a handicap of no higher than 6), but some may be turned off by the thicker topline. No love for lefties.

Bottom Line: Mizuno JPX-825 Pro Irons blur the line between game-improvement and players categories. These are not ground breaking, but rather an enhancement of the previous JPX-800 Pros. That’s a good thing for these who are all-round top performers. Solid, soft and deadly accurate. While the recommended handicap range is 6-18, you can bet there will be even better players putting these in the bag.

Tested: Mizuno JPX-825 Pro Irons (4-GW), Standard Length, Loft, 2 degrees up from Mizuno standard with Project X 5.5 Shafts (Soft Stepped 1X)

About Mizuno JPX-825 Pro Irons: The Grain Flow Forged JPX-825 Pro pushes the design limits to achieve greater forgiveness and feel in this players game-improvement iron. The 4-7 irons offer a deep CNC-milled pocket cavity that provides 17 grams of discretionary weight that is used for extreme toe-heel weighting providing plenty of forgiveness where you need it. The 8-GW features a full cavity design with greater thickness behind the impact for a more penetrating and workable ball flight for pinpoint accuracy in the scoring irons. Suggested handicap range: 6-18 (My handicap: 7)

Designed to appeal to both the game improvement and traditional iron player, these hit the nail on the head. The not-too-big, not-too-small size appeals to a broad range of players. Previous offerings had cavity stampings that were bold and polarizing. The JPX-825 Pros tone this down a bit. The black cavity graphics are understated, but at the same time are edgy enough to hint there’s technology helping you under the hood.


The satin-like appearance enhance the technical look. I do wish Mizuno would change the font on the iron numbering a bit. Really, font? Yeah, that’s a little picky, but its squared-off, over-sized appearance is a little dated.


With iron forgiveness vs. size, there is always a trade off. Mass is needed all around to help with forgiveness, yet a better player is turned off by thicker topline. Well, Mizuno has fooled you this time and you’ll be glad it did. The mass is still there, but thanks to a clever topline bevel, it appears more like a traditional players iron. You’ll thank Mizuno later.



I am a long-time Mizuno game improvement player, from MX-200 to MX-300 Pros to JPX-800 Pros. The latter were one step up from the MX series, and also taught me the importance of custom-fitting (read more on the Mizuno Performance Fitting System here). While these are a different shaft than my beloved 800 Pros, these were recommended by Mizuno and the performance reflected it.

After four rounds of with the JPX-825 Pros, these perform every bit as well as the 800 Pro model they’ve replaced. You can work these a good deal, or play your natural shot and just fire away. Long irons (4-7) employ an undercut cavity design (thankfully not visible at address) which helps with forgiveness and a hotter face for distance.


I didn’t find any groundbreaking distance gains, but the consistency was top-notch. The 8-GW have no undercut cavity and are extremely accurate, no doubt helped by the cleaner, scoring iron shape. You can score with these clubs, so get the putter ready.

The flight seemed a little higher to me in the long irons than my 800 Pros. That’s a good thing as it helps stop the ball on the green. I had no problems hitting these lower. Low punches, especially with the scoring irons, were spectacular. They flew low and stopped quickly and were fun to pull off.

We’ve all seen “Grain Flow Forged” proudly etched on the hosel of Mizuno forgings. They are some of the best feeling irons around. Feel is excellent and uniform with long and short irons despite the difference in the cavity designs. Somehow, these feel nicer than the JPX-800s they replaced.

These are more muted than a blade on mishits, but still provide great feedback at impact. If you flush one, you know it. Overall feel is excellent and uniform throughout the set. Not quite like a hot knife though butter, but very soft nonetheless. These are easily some of the best feeling clubs in the ‘players game improvement’ category.


The JPX-825 Pro Irons continue to blur the line between game improvement and players categories. They do everything well, in a handsome, forgiving forging.

I consider myself a “recovering forged-iron snob.” There was a time I wouldn’t consider an iron that wasn’t forged. Now, I’ve come around to believe technology can help in all clubs, including irons. Multi-material designs and castings all have their advantages for sure, but Mizuno packs technology into a forged iron like no other. Forgiveness, workability and soft feel. When you flush one, you smile. That’s what the game is about.

  1. Just bought jpx 825pros cos there wasn’t any difference apart from price with the 850s and I prefer the look on the 825s. Got to say I was a bit unsure with me being a 16 handicapper about playing with forged irons, but I’ve got to say these felt beautiful hitting a 6 iron at 175 yds which is a big improvement on my ping g10s just need some time if work to go and have a game with these beauties. What I’m getting at is don’t be put of with your handicap if they feel right then put in your bag!!!

  2. I’ve been playing the same course every Friday for over 20 years, averaging 85 or 86 over that time. I received my JPX-825 Pros on Wednesday, hit them at the range on Thursday, and shot 79 at the previously mentioned course on Friday. These are truly some fine irons. I hit them straighter, farther and higher than any set of irons I’ve ever owned.

    • A little advice; Love the 825 pro, got fitted at Edwin Watts, then went elsewhere for an Edel Putter, brought in the 6 iron and the fitter said something is wrong, the club is too heavy, initially he thought they were graphite heads w steel shafts, sent to Miz and they said THATS what was ordered, we changed out the shaft to a liter weight, picked up 9mph swing speed, went from 84 to 77. SWEET!!

  3. I started swinging clubs about a year and a half ago and started playing rounds less than a year ago. I’m down to a 22 in that time, playing Adams Idea Tech A4-R. I hit the 825-Pros, and they really do feel good. I’d rather buy a club that will give me room to grow (with full understanding of the practice required), and I’m considering the 825-Pros.22 to 18 doesn’t seem like a tremendous leap, but I’m new to the game. I’m missing the most strokes off the tee, not in ball-striking; but I’d hate to jump into some clubs that could hurt my game.
    Thoughts and/or opinions?

  4. I LOVE the way they number their clubs!… I HATE those tiny little airy-fairy numbers on the rest of their line… Reminds me of penmanship class in fourth grade!… Give me BOLD!

  5. I just picked up my 825 pros w/ aerotech i95x shafts that I had fitted at mk golf tech in SA,Tx and I’m very satisfied w the look, feel and weight. I switched from mp 60s w dyna gold s300 and found that the forged iron heads are similar but the steel fiber shafts w proper fitting is “the deal”. The ball speed was also hotter off the face in 825 pros over the mp 60s w my same swing speed. Being a 10-12 handicapper playing 1x week or so, I found the 825 pros just as sweet as Miura 505s and being properly fit for shafts I’m hitting 12+yards further w control and workability.

  6. I just put the JPX 825 Pro’s in the bagand after playing MP60’s for 4 years I find the difference in clubs like night and day JPX are much more forgiving. Don’t hesitate to try these if you are in the market for new clubs

  7. I purchased my 825’s around Christmas and have been using them since. The more I use the more I like. I do get better distance than my old Titliest 851’s. Had to go back and buy the GW for my 95-110 shots. I choke down and can control the distance very easily with 7I-GW. If you looking for forgiveness and consistent feel these will perform for you. I am hitting more greens than ever and a few more 2 putt pars never hurt!!!

  8. Wow. Just played my new 825 Pros for the first time. No offense to my wife or daughter, but today was the happiest day of my life. I finally set down my pride, benched my mp59/69 combo set, and along with a new mallet (ugly as sin) putter, put these so called game improvement irons to the test. I normally fire a 74-76 at my home course from the back tees (72.4/144). I only played 9 today, but with no warm up shot a 34. Here is the fun part; This was just a test of my irons so I hit no more than my 4 iron even off the tee. These irons are amazing. They are not overly big and I say this being a snob when it comes to asthetics. I love my mp69’s and collect scotty camerons (own 7). But along with still looking nice, the irons are awesome. Mishits still reach the green and do not curve offline nearly as much as my normal misses. Distance is slightly longer but the main advantage is consistancy. My approach into #9 was 171. I misshit a 7 short and left a 20 ft putt. For analytical sake, I dropped another and flushed one, thinking it would go long in comparison, and left myself 10ft short. A diff of only 3 yds, are you kidding me!!!??? Maybe you ate a gluten for punishment but me, I’d rather score.
    I am sure there are other good “players GI irons” out there too, but do yourself a favor, swallow your pride, sell your blades, and get yourself some forgiving irons! And the 825 Pros are as sweet as they get!

  9. Had the JPX-825 Pro’s custom fitted. Also hit the regular 825’s but the feel of forged was awesome and I hit the ball better according to the computer. Shot a 1-under round today (for 9 holes). My good rounds for nine have mostly fallen in the 3-over range. Also added the MP R12 Sand and Lob wedges. I love the look of the 825’s at address. The top line is the right balance between thick and thin.

    Previously had been playing Ping ISI-S irons. The feel of the 825’s when hit in the center really is like butter. Off-center balls also are not punished too badly.

    Do find someone good to fit you. I was surprised at the shaft I needed. I assumed I was an R flex, but needed a stiff. They used the same device on me I saw then use on Luke Donald in a Mizuno video in addition to the launch monitor, and bent the irons to match my lie angle.

  10. Just got these, hit the range and then the links. I have been struggling to find a new set ( played 762 DCI) for a couple of years.

    The problem is that all of the newer technology wants you to swing and hope the ball goes far and maybe near the pin. I am not a big offset player and like to craft a shot. Nothing crazy a fade here or the a punch or knockdown every so often. These clubs are great for that.

    I am very very satisfied with these. Found them to be very forgiving for a players iron (10 hcp, at best a 7).

    Distance? I picked up a club in this area as I was using some other irons of late (not the dci’s). I think they certainly help although I don’t really need the distance more so the accuracy.

    In all these irons feel excellent, allow you to work it a good amount and feel like laser pointers. I am good for another 5-7 years. Play well!

  11. I just bought Mizino 58 I love the look and feel of them but the rifle shaft on the 4-6 iron have a high kick point,where I think it should be a lower kick point.The 7-PW feel pretty good.Im thinking about putting a True Temper Multi Step Lite Steel Golf Shaft in the 4-6 irons I’ll post something after I give that a try.I wish I would have bought the JPX-825.
