Mizuno’s 2026 M-Series has one aim and that is to reclaim the No.1 spot in better-player irons for the brand. The M15 irons are apart of this new range as Mizuno’s players-distance option.

I’m not exaggerating when I say, after extensive testing, that the M15 might be the most complete Mizuno distance iron yet. Read all about them in our review below.
NCG Summary
NCG SUMMARY
The Mizuno M15 is one of the most complete and balanced players-distance irons on the market for 2026. It combines the feel Mizuno is famous for with the modern demands of speed, height, and forgiveness, without spin rates dropping.
In many ways, it performs like a blade in terms of trajectory and stopping power, yet delivers the ball speed of a distance iron.
PROS
- Outstanding blend of speed and spin
- Consistent performance across the face
- confidence inspiring look
- Long irons are really playable
CONS
- None
First Impressions
Visually, I prefer how these irons are constructed from one complete material rather than having the back cap glued on like the M13s. The whole look is very clean. I like the silver logo and minimalist text.
At address, they are noticeably thicker than the M13s. It is very much a confidence inspiring look with a slightly thicker topline and a marginally longer blade length compared to the M13, offering more confidence. Saying this it is very much an inviting looking set of irons, yet still don’t appear to be overly bulky.
We all know Mizuno’s priority, when it comes to irons, is to make sets that look good and feel good. They have certainly nailed that with the M15s.
NCG Verdict
The M15 is significantly longer than the M13 across the bag. They certainly play up to the players-distance tag. I found the M15s produced 10 yards more carry with a seven-iron and around the same with the longer irons.
I was able to get my five-iron up to around the 200 yard marker thanks to a ball speed as high as 135mph. Previously, I was only really ever able to achieve these numbers from a set of strong-lofted or low spin irons.
With a hollow construction I expected the forgiveness to be very good on mishits and it was. The drop off in performance on my poor strikes was only marginal, retaining strong ball speeds and, crucially, plenty of spin.

The M15 produces an impressive blend of high launch and playable spin. Many hollow-body irons generate speed at the cost of spin, but the M15 avoids this trade-off.
My mid-iron shots regularly reached peak heights of 90–95 feet and carried spin rates that allowed them to stop quickly. The result was a ball flight that behaves like a traditional players iron while travelling with far more speed.
Let’s touch on the technology quickly. The bulk of the innovation comes in the seven-iron to the four-iron, mid irons.
These irons contain a large internal tungsten weight, 50.3 grams, suspended inside a fully hollow chassis. The tungsten helps to deliver high launch and a mega forgiving club. Mizuno pairs this with a 4135 Chrome Alloy face that is extremely thin and highly flexible.
Often when I hit a set of blade irons the centre strike feels good but you can tell there isn’t a lot of mass behind the ball. Whereas with these clubs it feels as though I was shining a sledgehammer through it. They felt really strong and stable, which is great.
Final Thoughts
Overall, I think the M15 is the best hollow-body iron Mizuno has produced. It looks good, feels better, and performs exceptionally well from long iron through to wedge. My concern with hollow head irons is that the spin tends to drop off, so the fact the spin rates were high with these was impressive.
Any golfer in the market for a premium players-distance iron should consider the M15 a top-tier option.
