Titleist has been seeding their new T-Series iron lineup on Tour since the Memorial and select fitting events for a while now, however, today we finally get to share all the under-the-hood details on just what is going on this time around. The success of the previous T-Series among amateurs has been well documented, but people forget that they have also been a part of keeping Titleist as the most played brand on Tour for eighteen of the last nineteen years.
So, where do they go from the success of the previous T-Series which cleaned things up and streamlined the lineup? They lean even more on their design team who continues to flex their willingness to keep evolving and optimizing in order to continue being a standard bearer in the industry.

2023 Titleist T-Series Irons
Sure, you can likely predict that Titleist is talking adamantly about the newest T-Series irons bringing even more feel, better looks, and higher performance than the previous version. If you hit the previous versions, then you also know those are lofty goals. The manner at which Titleist is attacking this version though, is befitting of the brand, they are one who grind over the details, all the details, and that certainly appears to be the case here from their initial discussion:
“The new T-Series irons embody a unique approach to iron design and creation,” said Josh Talge, VP, Titleist Golf Club Marketing. “Down to the finest details, this new line delivers best-in-class performance with stunning aesthetics and feel. Each model has been designed to feel as good as it looks, look as good as it performs, and perform better than any iron we’ve created before it.”

Going forward, the T-Series will be a four-pronged iron release. Where last time there was a bit of redundancy in the naming methods, now it is simplified with the T100, T150, T200, and T350. Yes, more numbers, but the system will make perfect sense when we dive into just what each head is intended to do, and how it does it.

This release is once again making it fun to see how far Titleist has come in terms of embracing what they do best, and how they do it, while accepting that trends change. The emphasis on creating four irons that will allow golfers the confidence that they can and will hit their intended numbers with the accuracy Titleist is known for, while also acknowledging that it may mean a blending of the designs to find the right fit for the individual, is a cornerstone to the new T-Series. In fact, of their Tour staff, almost 80% are playing some form of a blended setup. To aid this, you will actually be seeing 5-irons make their way to fitters to ensure the best blending possible for those who pursue it.
The best way to break down the unique characteristics and changes, however, is to go iron by iron, so let’s get into it!
2023 Titleist T100 Irons
The T100 is staying true to its roots in being a true players cavity back iron for the most discerning and demanding ball strikers on the planet. What you may not fully realize is that the T100 has actually been the most played model on Tour since the first iteration in 2019, and with the 2023 model the early adoption has been immediate.

Titleist is calling the T100 “The Modern Tour Iron” and rightfully so, this is a CB which is aimed at precision, control, and feel/sound. With the feedback the previous version has garnered, it had to be a daunting task to tackle making it even better, but refinement was the ultimate goal here, starting with the forged dual-cavity construction itself. Through new CNC face milling to shift the CG slightly, combined with the brands already precision driven forging process, they claim the T100 is more solid feeling at impact this time around to give even more immediate feedback on strikes to the user.

Internally, Titleist is implementing Tungsten to the heads in order to shift the CG to their goal locations and achieve the feedback their Staff has asked for. To do this D18 Tungsten is being brazed via a 2000-degree aerospace process. Why? According to Titleist it means the forged feel/feedback they desire is not hampered in any way compared to some other attachment processes.

Along with the nee CNC Face Milling processes for precision off any lie, Titleist also took feedback and input from their Tour players as well as Vokey grind experts to make a better sole. This T100 has had its variable bounce smoothed and softened in the trail section in order to create better, faster, cleaner interactions to and through the turf.

T100 will come standard with True Temper AMT Tour White shafts in steel, while the Mitsubishi Chemical Tensei White AM2 is the graphite option, both paired with an all-new proprietary Titleist Universal 360 grip.
2023 Titleist T150 Irons
You read that correctly, the T150. Last time around, Titleist presented the T100S as an alternative to the T100 for golfers who wanted something still in a player type profile but with more power. The T100S was a definite success, but the T150 move cleans up any potential confusion and looks to cement it as the iron for golfers who want T100 precision, but more speed, distance, and forgiveness. Makes sense that Titleist is calling it “The Faster Tour Iron”.

In a familiar move, the T150 is built on the same fully forged base design as the T100 is, but it has 2-degree stronger lofts and a slightly larger profile comparatively. That specifically means a more confidence inspiring look at setup differentiated from the T100 where the T100S was essentially identical. Fret not however, the offset and blade length remain identical to the T100.

The design is fully forged to bring feel to the stronger lofts, and the “Muscle Channel”, which made surprising speed jumps in the T100S, is back in the T150 albeit blended to the new shaping of the iron in order to keep the precision look Titleist wanted. The channel is situated closer to the face this time, but to a point where during internal testing it retained the feel/sound which the company demands.

While some might be saddened to hear the profile changed a bit from the T100S, the consistent feedback was that it was perhaps on the small side. So, a slightly thicker topline and wider sole while keeping the blade length and offset the same makes for a more friendly look. Not to mention, those changes also allowed Titleist to shift the CG lower in the head for easier launch even at stronger lofts while keeping all the feel in the forging combined with the new softening of the rear sole.

For the T150, the standard steel shaft will be the Project X LZ and Mitsubishi Chemical Tensei White AM2 for graphite, both with the new proprietary Titleist Universal 360 grips.
2023 Titleist T200 Irons
Ah yes, the T200. This iron has for the past couple of releases been simultaneously beloved for the sheer performance it offers and faced some criticism for the sound/feel differentiation from the T100. You would be hard pressed to find someone who didn’t like the visual change of the last T200 which created a much more players like look that was Titleist clean as opposed to all visual tech. However, the goal remained to create a jump in feel while improving the look even more.

The T200 is the “Players Distance Iron” of the T-Series and so every effort was made to keep or increase the trajectory and stopping power that blends with sheer ball speed potential. However, while the last T200 nailed making such an iron look like a player’s iron, it still needed a jump in feel. It is for that reason that every single change was intent on helping remedy that.

Internally, there is an all new structure that makes for more stability in the frame/chassis of the irons which works in conjunction with an evolved Max Impact Technology power source. The Max Impact now fits much more snugly to a new dual taper forged face and with the stiffer frame Titleist claims it has a much more solid feel/sound at impact now. The T200’s also use the same D18 Tungsten and aerospace brazing technique as the T100 and T150 to dial in the CG.

Even with all the changes to improve the sound/feel, Titleist states that the new T200 have the same shape which proved so impressive in the last release. Add in the improved variable bounce sole with more relief on the trailing edge now and the T200 may be even more versatile. However, it is all still tied together with a bow that is a clean, and concealed, cavity look which based on initial pictures flows effortlessly into T100 and T150 and boasts identical offset and blade lengths as them to boot.

At standard, the True Temper AMT Black (steel) and Mitsubishi Chemical Tensei Blue AM2 (graphite) will be the options using the new proprietary Titleist Universal 360 grips.
2023 Titleist T350 Irons
Finally, “The Ultimate Game Improvement Iron” according to Titleist joins the T-Series. This is the T350, and the objective in design was simple, make it go high, long, and far while keeping forgiveness across the face. How did they accomplish that? Well, they went hollow body of course. But fret not, there has been a lot of attention to making sure the T350 blends with the rest of the lineup visually, rather than standing off on its own.

The T200 chassis is the basis of inspiration for the T350 and that is what allowed more forgiveness, launch, and power. The keys are again the evolution of Max Impact Technology along with a new dual-taper forged face and dual tungsten weighting system. A good way to think about it is Titleist has taken all the tech they use in the other T-Series irons and put them into a profile that all players can enjoy.

By moving to a multi-material hollow build, The T350 seeks to create more speed all the way across the face along with better retention of both speed and spin on misses. Like the T200, there has been a lot of discussion from Titleist about being relentless on getting the sound/feel right, which is the make or break for any hollow body iron.

Through the same techniques as in the new T200 via the Max Impact Tech and polymer adjustment in relation to how it snugs to the face, they believe the sound/feel is right. Another aspect is using the same variable bounce sole with trail relief that the other three irons to also impact that feel as the irons gets into and out of the turf. Perhaps there is no better backing of that than the T350 actually getting play on Tour, yes, you read that right.

Big MOI, lower CG, as well as across the face speed and forgiveness with emphasis on dispersion are all things golfers love in game improvement irons, but the way Titleist is visually tying it together might make it a smash hit in the segment. The hollow design has allowed for the tech to be more concealed in the T350 like its sibling the T200, and while usually golfers in these irons love visual tech, this is much more in line with the cleanliness and class they expect out of an iron with the Titleist script on it.
The T350 is paired at standard with the True Temper AMT Red in steel and Mitsubishi Chemical Tensei Red AM2 for graphite. But, as with the whole line, there will be a plethora of custom options available.
The Details
All four of the new T-Series irons will be priced at $200 per club or $1,399 for 7-piece in steel and $216 per club or $1,499 for 7-piece in graphite, very much another example of the continuity Titleist is striving to maintain in their flagship iron lineup. The irons are all in play on Tour already with one of the fastest adoption rates Titleist has seen. Officially, the T-Series will hit shelves on 8/25/23 with fittings available now.

It’s pouring rain this morning but tomorrow looks sunny, so things should be nice and soft and receptive. Don’t have too much time left in the season, but I think these might have some magic in them.

I want to try a set of them with Axiom 105s shafts. May need to go see the boys at CC. The Axiom in my hybrid is so good. Soft stepping the 105s shafts could be really good in the 150s

I don’t envy your long cold winter. ???
Didn’t score too great yesterday mostly due to the driver, but the irons definitely saved my bacon a few times and helped me salvage an average score:
Hole 10 – 8 iron to 3 feet for birdie
Hole 12 – PW to 2 feet to save par after taking a drop off the tee
Hole 15 – AW to 3 feet for birdie
I just continue to really enjoy having this combo set in the bag and I am super confident and comfortable with any of these irons in my hands. Loving the higher ball flight paired with the KBS shaft and I am able to control my distances with relative ease.
The part I am loving the most of these, is the gapping to do flighted shots, punch shots, or throw them up in the air, they are VERY workable irons…from my fitting I swapped out to the UST Mamiya Dart V shaft Concept shafts…I was fitted into KBS TourV’s but with as much Sim time I have, I foudn them hurting my elbows and wrists…
LOVE these shafts, and love the consistency…
in the middle of full rebuild of our Simulator in teh house, so have not spent time doing and redoing distances and working numbers with punches etc. but will get them done…
I’m having a lot of fun with the T-150’s so far, and I think that these are going to stick around for a long time. The sim place hosting our fall league uses dimpled rocks, and these still feel pretty good, but with a premium ball they feel even better – that “Finding Feel” was a really cool watch, and the work that went into these things to find the combination of sound and feel has paid off. I like the view at address with these irons, the offset is very subtle, and it’s helping me set up the face a little more open. Got a few rounds left to enjoy these outside yet this year, and I am looking forward to them.
Didn’t have too many highlights with these today besides firing an 8i to about 7’ on a hole that’s given me fits all season and burying my only birdie of the day. That might have been one of the nicest iron shots I had all year and man did it ever feel good.
[ATTACH type=”full”]9302482[/ATTACH]
This 6i into the wind never left the flag, and the guys on the next tee were going nuts about it almost dropping. These irons are so much fun, and they sound so good. Really like the way they are playing for me, the late season switch might have been a little silly, but so be it.
Having a lot of fun with the T-150’s as we move into the winter – I enjoyed the Blueprints but I don’t know if it was truly meant to be. For the last few years I’ve been a low-spin player with irons and wedges, but last night I saw spin numbers around 7K with a 7i, and for off mats I’ll take it. I was messing around during the warmups trying to move trajectory around, and these irons are much more capable than I need them to be. Pretty excited to see what the next gen of these is going to look like – they feel great, and sound very nice.

Next gen could be special. In the mean time I’ll experiment with something else. Super curious what comes next.
Really had my best round all around with the newish sticks today. Had relatively close birdies converted with the 8 iron, GW, 7 iron, 9 iron, and PW today and I was steady on all of the par 3s. The more I play with the T150, the more I enjoy them. Stoked for my next round.
Little bit of a bag shakeup/experiment this week, dropping the 4U & 5H in favor of the set 4/5i, and I’ve been pleasantly surprised at what I saw out of the long irons in the T150. I got a little spoiled out of my last few players irons with easy launch in the long irons, and the 150 is no slouch in that department either. I may have to do some lie angle tweaking with these, but I think these are sticking around for a long time. I really enjoyed the Finding Feel YouTube video on this release, and I think they nailed the feel. It’s soft and powerful at the same time, and I’m excited to see what they are cooking up to make these even better.
Last two rounds with the irons has been pretty darn good. My confidence throughout the whole bag, and especially with these irons, is through the roof at the moment. If everything comes together, I think that I can put together something pretty special (for me). Stuck several shots in close yesterday, but putting was just a fraction off and I couldn’t get anything to drop. Also, I’ve touched base on the higher launching shaft that I have in my T150, but every time I flush an iron, I am simply in awe at how high the ball launches. I have never had the confidence to hit the ball high (especially when I have to get over something), so having that ability in the bag has been wonderful.
Updated my wedges due to use and groove wear which made me realize that my 48* T150 has seen over 150 rounds already and is my go to greenside club. Lots of wear on the face so I ordered a new 48*, same numbers, and look forward to seeing if ball flight and spin difference will be apparent. The original 48* still stuck well on greens, but with greens firming up soon (pronounced “FROZEN OVER), added spin might be nice. Over a year of use and the T series have been reliable friends on the course!
I think the T150 may be changing my thoughts on set make-up after the last few rounds on the sim. These long irons are awesome, and I’ve been getting some excellent results out of the upper end of the bag recently. It’s been a big visual switch from the U505 4U, but I was able to score GIR’s on 2 long par 3’s last night, and hit the 4i to 17’ to set myself up for eagle on a par 5. Kind of kicking myself for not going this route initially to start the year, but it’s feeling like home right now.

Love to hear that! I like the T200 4-iron, but I have kicked around the idea of snagging a T150 4-iron since I like the rest of the set so much.

I kind of pondered going that direction and ordering the T200 4i or utility build but I’m really happy with how these are performing from top to bottom. Really fun to see the ability to be precise mixed with a ton of power.
Alright… gotta brag on myself a bit from likely a top 20 shot in my golfing lifetime with a T150 6-iron from about 175 yards.
The ball was where the yellow dot was and the red dot is where the flag was tucked over a bunker on a narrow part of the green.
We are playing a two man scramble and my partner punches out short of the hazard. I take a big rip and hook the 6-iron about 12 feet past the pin. The thing had to hook like 40 yards, which is wild for me since I really struggle working the ball left to right. As was the theme on the weekend, we missed the putt, but I am still jazzed about that shot.
[ATTACH type=”full”]9308800[/ATTACH]
Absolutely in love with how these feel. Kind of kicking myself for going in a different direction to start off the season, but such is life. They are absolute speed monsters on the monitor, and I like this higher ball flight a lot. The only other 4i’s that I have in the stable currently are blades, which make the set 4i look incredibly forgiving, but I’m very impressed at how forgiving this thing actually is.
Pretty good outing this week with the 150’s, the additional spin I’m seeing is much appreciated at the lower end of the set, and I love how easy the launch is with the long irons. I’d be very curious to try the set gap wedge ?
Having alot of fun this off-season, and the T150’s are adding to that in a big way. The long irons are powerful – I wouldn’t have had playing a set 4i on my bingo card for 2024, but I don’t see a utility or hybrid being put back into that slot anytime soon. From 8-PW, I’m getting enough spin and height even off mats to generate hit and stop, and I’ve had some PW’s zip back a bit. Got a ton of confidence in these at the moment, and I’ve shot some great scores so far this winter with them. I initially had some mixed feelings about the way the finish looks at address, but it’s growing on me – it’s not a deal breaker by any means, and I’m not sure what I would change about it. Currently the only thing I would change about this set is replacing the Tour Velvets, but that may happen closer to the spring.
The feel of these is addictive, and they offer a pretty satisfying thump to accompany. The set gap wedge still is heavy on the ponder list for 2025, but other than that these are staying planted for next season. Like what I’m seeing out of peak height, spin, consistency – they are just working for me.
Having a lot of fun with the T150’s, and now that I pulled the trigger on the set gap wedge, am impatiently waiting the quoted 2 weeks to give that a run against the F Grind 50°. That wedge slot hasn’t typically been a short game club for me, but I’m going to do some experimenting with it and see how it plays around some greens I often play at home. Despite me not walking a ton with my clubs (obviously ??), they are starting to pick up some battle scars, and I think they look pretty good with some wear and tear.
I go back and forth between the 48* T150 and an F Grind 50*. I can get a bit more sloppy with the Vokey (head is a bit bigger), but the feel is significantly softer with the 48.
Had a reallllllly solid last few days with the combo set. Some really nice recovery shots with all kinds of shot shapes that were really fun to pull off and attempt. However, my driver and putter have let me down, but the irons have helped me salvage some scores that I was not upset with. We were lift, clean, and place the last few days which helps pulling off some recovery shots, but I just have so much confidence with the T150 (and T200 4-iron) in hand.
Irons were a little hit or miss today, struggled to find the bottom of my swing a bit for the first little while, but it came around and the T150’s started to shine. Really happy with how much spin I’m seeing out of these irons, it’s been a struggle point for me in the past with my delivery, but that doesn’t seem to be much of an issue so far this winter. The stock LZ’s feel so good in these, but the Tour Velvets are getting replaced before the outdoor season starts.

I want to try the one length. But hitting the 150s good these days.
FedEx man came through and dropped me off a late Christmas present. Looks like this set gap wedge flows really nicely shape wise from the 9i & PW. Got a sim round booked for mid-week so I won’t need to wait long for a test flight. I know during an Experience or two it’s been discussed why more OEM’s don’t do a set GW in players irons, but it’s nice to see, and I’m excited for this comparison between the Vokey I’ve been playing.
Had a pretty good first run last night with the set gap wedge. It fills the yardage gap I would like really nicely, it’s visually really similar to a bladed wedge at address, and it spins like the rest of the set does for me. I have a lot of confidence in these irons, they check quite a few boxes of the things I’m looking for, and I have a ton of confidence in them after the last few weeks of really decent ball striking.
I am enjoying my t series irons as well. I have had them for almost a year. I went with a combo set 7-P in the 150’s and 6-4 in the 200’s. I have been pondering the set Gw as well and maybe swapping the 6 out. I love both series well. And hit them super well. Longer irons ten do be love hate. At least the 4 is. I can hit the 6 175-180 easy distance and the falls just ahead. Now if choose to step on a 7 I can get it to almost cover 170.. (if I do my part well).
The GW is where I am puzzled I play a vokey 50 but tend to struggle getting the similar gap from the pitching to this club on full swings..
Any thought process help?

I bought a replacement T150 48* a few months ago to replace the the one that came with my original set. it is such a nice club and very versatile. It really does blend well between the irons and wedges, especially Vokeys. Glad to hear another is being put into play!
