Mizuno Pro S

T Todays Golfer James Hogg · reviewer · Jan 2025

I’ve had the pleasure of playing golf over the holidays with both the Pro X and Pro S golf balls, and I’ve been majorly impressed by how both of them performed on the course. I’m a bigger fan of the Pro X because it suits my game more, but I still enjoy playing with the Pro S – read the full review here .

My review of the new 2025 Mizuno Pro S-1 muscle back blade iron which looks beautiful & feels amazing! I run it through it's paces hitting the 5 iron, 7 iron & 9 iron both indoors on TrackMan as well as outdoor on grass.

The shape on these irons is great, with a more compact look and a slightly shorter blade length compared to the Pro S-3 irons. The topline is thin, and the toe has a slightly sharper look to it that I think most better players will appreciate.

It's the Mizuno Pro S4 and this perhaps is the cleanest, best looking players cavity iron I've ever seen. I'm loving the feedback off the face. And today we're going to bring in Harrison Arnold to do some testing and give us the feedback on performance as well. Oh yeah. Oh, I like these, Drew.

Focusing solely on the Pro S (you can read the Pro X review here ), I’ve genuinely been blown away by how well this golf ball performs, considering its predecessor – the RB Tour – was very underwhelming in my eyes.

The S3 irons are ideal for golfers who prioritize feel.

Well after playing my second round with my new Mizuno Pro S-3’s safe to say i’ll play mizuno irons for the rest of my career firing my best round to date 78!

The new Mizuno Pro S-1 irons are the latest Mizuno forged muscle back iron offering and include all the trademark characteristics of Mizuno forged irons from the past that golfers have loved. The Mizuno Pro S-1 irons join the Mizuno Pro S-3 irons in the new Mizuno Pro Signature Series irons.

As a former, longtime Mizuno gamer, I hope the brand gets this sprawling lineup in check so there’s more spotlight for excellent offerings like the Pro S-3.

I've hit Mazuno clubs at the PGA show, but this blue box arrived last week, and I'm so excited to dive into these gorgeous irons that are hitting retail in September. These are the brand new Mizuno Pro S1s.

I'm I'm pretty impressed with where that ended up.

One of the finest feeling blades on the market

P Plugged In Golf Matt Saternus · reviewer · Oct 2025

The Mizuno Pro S-1 irons look great and perform just as you would expect a traditional forged blade to perform. Feel is mediocre, especially from a company with Mizuno’s reputation.

While both delivered impressive data in the simulator, we found them ever-so-slightly lacking compared to their competitors in real-world course conditions.
