I recently went through a Titleist fitting for the new 2025 T-Series irons and utilities. I hit every iron, the T100, T150, T250, and T350, as well as the U-505 and T250-U utilities. And I can sum up the entire fitting by telling you this T-Series is Titleist's GOAT. No exaggeration.
Something was legitimately improved in every model. In some ways even significantly improved. And more than any line in Titleist history all four iron models blend about as perfectly as possible for combo variations. There's actually a fifth iron model as well - the T250 Launch Spec, but I didn't test that iron. I'll let you know what my ultimate set wound up being at the end.
This T-Series fitting review will go over what I experienced hitting the new irons and utilities with an emphasis on differences between the models and different performance I saw with each. I'll also hit on some of the new tech story for each iron and utility to help distinguish and explain performance differences I saw compared to the previous T-Series generation of irons.
Before we get started I want to say there are few things I enjoy more any given year than a Titleist fitting. My fitter Justin Long at Windmill Lakes Golf Club is a phenomenal fitter in every possible way. If you're looking at any Titleist clubs at any time during the year go see Justin. It'll be one of the best fitting experiences you ever have.
So I arrive at Windmill Lakes for my fitting with a pretty good idea of what the new T-Series irons and utilities are all about. Or at least I thought I did. A few days prior to my fitting I told you about the new construction and technologies in Titleist's new line. But what's on paper has to translate to the course. And during my fitting I learned the hype wasn't merely justified. Performance actually overdelivered.
T350 Irons
Let's start with the T350 irons. And as I mentioned earlier the first thing you notice is how well it blends with the rest of the T-Series irons. More importantly for me however was after my first few swings I also realized the feel of T350 is so much improved I'd almost call it an entirely different iron.
T350 are hollow but they felt less hollow with less click at impact than the previous gen. And I think in part this is because the T350 construction is based more on the T250 than it ever has been before (both are all-steel construction for example). In fact I'd almost call T350 and T250 the same category of irons (similarly to how T100 and T150 are a same category). T350 is still not as solid and strong feeling as the T100 and T150 for me, but they're closer to a solid feel than a hollow feel now and that's just outstanding.
If you're choosing new Titleist irons just based on ball speed and distance I'm telling you T350 is going to win for almost everyone. It's simply designed to do this. I saw my highest ball speeds with T350, and almost 5 mph faster (on average) than the T100 as an example. You also get forgiveness all over the face with T350. Dispersion with T350 was consistently down the center line with a few shots out to maybe 10 yards left of center. And they even launch easier than the previous gen. Utterly fantastic.
I'm spending a lot of time talking T350 but might as well say right now these were not the irons I wound up with. I'll explain why in more detail below. It's worth mentioning however as I was hitting T350 I legitimately thought these could be the ones. They are that good, and I'm normally not fond of the larger game-improvement iron shapes or feels.
T350 is the largest head of all new T-Series irons (longest heel to toe, widest sole, thickest topline) but they just looked cleaner and more compact than previous Titleist game-improvement irons. And as mentioned the feel resonates more than ever. Ultimately Titleist did Titleist things with T350 and these will be a meal ticket to playing consistently better golf for a lot of players.
T350 were the lowest spinning irons of all models (almost 750 RPM lower on average than the next closest model), but at the same time were pretty much identical (just a few feet lower) to T250 in peak heights so I still had plenty of stopping power. T350 decent angles were the shallowest of all iron models, but only a few degrees lower than T250. Before we moved on to the T250 I actually started thinking that a mixed set might be in my future. And Justin told me Titleist fitters are seeing about an 80-percent rate of players (including Tour players) winding up in blended/mixed sets.
A Quick Note on the New Titleist Fitting System
Titleist has a new fitting system that dials you in even more. I won't go deep into this but you used to only be able to go 2 degrees flat, standard, 2 degrees up, and 4 degrees up. The new fitting system allows you to go anywhere from 2 degrees flat to 4 degrees up by 1 degree increments. And it also allows 1 degree less loft, 1 degree more loft, or 2 degrees more loft. Titleist can now also fit you with the ability to change weight by up to 6 grams.
So Titleist isn't merely fitting you into the best model irons for your game. They're also finding ideal height, distance gaps, and feel unique to your swing for your entire set. And without a fitting like this I'm not sure you can know that you're getting those ideal landing angles, heights, and distances, whether you wind up in a mixed set or not.
Of course I'm still going to hit mediocre shots, it's the bane of a being a mid-handicap golfer. I live with it. But when you get dialed in during a Titleist fitting, you're getting more consistency in windows, spin-rates, and distances that translates to hitting the green more often as opposed to coming up woefully short or sailing one over. As I said earlier, absolutely love Titleist fittings.
T250 Irons
Next up were the T250, Titleist's players distance irons. If there was an issue or problem I had with the previous gen T200 it was the back cavity piece. Quite frankly (sorry Titleist) it just wasn't very good. It was designed to help with sound but for me it created too much click at impact. The new T250 is a more solid piece in that you still have high density tungsten in there but now it's better enclosed (versus the polymer-plate like thing Titleist used with the last gen). And my first few swings with the new T250 felt stronger and sounded deeper than the T200.
T250 also felt heavier than T350 from my first swing (bit of a surprise being a smaller head) but that's more my preference so I liked it. By heavier I mean I felt more head awareness through the swing. T250 also felt and sounded softer than T350. And for better players in particular who equate sound with feel this consistency will be greatly appreciated. Titleist has said T250 is a transformational re-design but it's not just appearance, sound, and feel that's improved.
Consistency of dispersion was even better for me with T250 than T350. With T250 my shots stayed within a 7-yard from center window both left and right. There wasn't any left bias like there was with T350 (I think primarily because of less offset with T250). Ball speed with T250 was about 2 MPH less than T350 on average, but I can live with a few less yards of distance for the kind of outstanding consistency T250 gave me.
T250 also spun about 750 RPM more than T350 and had a slightly steeper decent angle on average. That's always useful. And peak heights between T250 and T350 were almost identical even with T350 being stronger lofted irons. Surprisingly, I did see for my slower speed swings that T350 launched the ball to higher peak heights than T250 (at comparably slower swing speeds). So this might be something to consider if you're a slower swing speed player. And for what it's worth T250 is still compact looking but looks slightly longer heel-to-toe than T200.
At this point I was thinking T250 are my irons, maybe with a T350 3-iron or new utility (we'd test those out later). I liked the smaller shape and less offset of T250 and the feel was even more solid than T350. The ability to go both left and right was easier with T250 and I saw tighter overall left-right dispersion with T250 not only compared to T350 but also compared to last gen T200. I also put better swings on T250 versus the T350 (will talk about this more below). T250 was clearly in the lead for me at that moment.
T150 Irons
Before I go into the T150 irons just a quick something about myself. I love the feel of great struck shots. You'll hear some of the self-professed equipment experts out there say that feel at impact doesn't improve performance. Fine, will give them that. But feel at impact increases the joy and pleasure and satisfaction of hitting good shots.
You hit a good shot without great feel and it's like having a party without music or presents. It's like scoring a touchdown without any kind of celebration. For me better feeling irons makes me want to hit better shots more often, wanting that feel is almost Pavlovian. And the new T150 irons made my heart flutter.
First swing with T150... pured. Next swing with T150... pured. Again and again, pured, pured, pured. These were glorious. And I can say this now in public (I did tell some of you this in private over the last few years), but I hated that Titleist made the last gen T150 bigger than the T100S. Hated it, and made no sense to me. Happy to report the 2025 T150 are again smaller, more compact, and look more like the T100 irons. And never get tired of hearing Justin tell me, "Good one there!"
And quick fun story, Justin told me the Number 1 played Titleist iron on the LPGA Tour was still the T100S (as opposed to last gen T150). So Titleist wanted to make the 2025 T150 closer to the T100S size than the last gen T150. I don't care why Titleist did it, I'm just glad they did.
As I continued hitting T150 I realized there was a common theme with the new T-Series irons. Again the new T150 felt and sounded stronger and softer compared to my last gen T150. And in fact the T150 also wound up being the strongest, most solid, and softest feeling and sounding irons of all the models I hit in this new T-Series lineup. That deep thwack sound and feel of T150 gliding through the grass and then that trackman beep seconds later recording my data. Just inject T150 right into my veins.
Now here's where it got really interesting. My average ball speed with T150 was nearly identical to the T350 flamethrowers and faster than T250. Ten of the 12 longest iron shots I hit were with T150, and dispersion both left and right and with overall carry was the tightest of all three irons I'd hit to this point. My peak heights with T150 were consistently the most ideal, descent angles the steepest, and spin rates the highest. T150 was just flat out amazing.
First let's give Titleist credit here. Whatever they did with the overall design (you can go over to the Titleist site to read about all the tech) the new T150 are simply better than the old T150. I can't say in exact numbers (maybe 400 to 500 RPM) but I know the new T150 spin more than the last gen model. I don't know if it was a conscious effort by Titleist to do that. I don't really care what the reason is to be honest. I'm hitting shots with T150 that are long, consistently more on target, and with phenomenal and improved stopping power. I'm not sure the new T150 are longer than the old T150 but the 2025 models definitely gave me better dispersion and descent angles. And I think we're going to see a lot of players who agree. These babies are freaking tactical.
Some Fitting Perspective
Now remember that bit about me hitting T250 better than T350? Well I hit the T150 better than all the irons in this new 2025 lineup. And by better I mean I consistently put better swings on the ball with T150. And again it's worth pointing out why a Titleist fitting is so important.
I'm talking to my fitter Justin and saying it's crazy that T150 are giving me the best shots of all the irons I'm hitting today. He knows me though and knows my swing so maybe it wasn't surprising to him. T150 are not designed to be massively forgiving like the T350 (or even the T250) but I was clearly hitting better shots with these. They're not designed to be distance machines like the T250 but I'm hitting consistently longer shots with T150 and with tighter dispersion. And here's in part why.
I don't take an overly big divot with my irons and I have a shallow approach into the ball. And Justin told me that the wider sole and chassis of an iron like T350 (or even the T250) makes it harder for me to get underneath the ball with these irons compared to the more compact chassis and smaller sole of the T150 (and T100 for that matter). It's all about ground interaction, like how a wedge goes through the turf.
Justin gave me an example of how certain players don't hit good shots with wedges that have too much bounce. And it's not because they don't have good technique, it's because these particular wedges aren't good for their particular shallower swings. I'm always changing my swing and ball position and anything else I have to change when I'm testing and reviewing different types of irons for you guys.
But when I play just to play and swing my swing (or in this case get fit for irons that fit my natural swing), narrow soles work better for my shallow approach into the ball. I mention all of this because the right sole width can lead to better contact regardless if a particular iron is designed to be the most forgiving or not. And you just won't know this without a fitting.
T100 Irons
I can sum up what the new T100 did for me just by telling you when I asked Justin, "What irons would you have fit me for if the T150 didn't exist? He said immediately, "the T100." Because the T100 and T150 are very similarly shaped I just put better swings on T100 than with T250 or T350. Dispersion was the second best with T100 for me after T150. Though I hit the T100 shortest on average of all the irons. Justin said he would have made adjustments in loft and shaft to get me where I needed to be had we gone T100. And honestly I also found these 2025 T100 irons to be easier to hit and easier to launch than the previous gen T100.
I never really cared for the T100 style of irons because they didn't have quite enough forgiveness on mishits for my game. But that's clearly been added with this new T100 series. I noticed improved launch on strikes hit low on the face (and towards the heel). And as my dispersion showed there was also a greater stability with the new T100 compared to the previous gen. The new T100 looks to be generally the same shape of head as the old T100 so I'm assuming there's some new design or construction aspect that's made these a more forgiving iron.
I won't go into all the iron shafts I tested. You can check out the iron shafts available on the Titleist site along with all the iron specs. I will say the new Project X Red steel shafts were best for me. The most control, consistency, and even head awareness in transition. And they're designed to give you a little more launch and spin. Another Titleist fitter who was with us during my fitting told me he just fit three players into Project X Red a few days before.
We next went into different 4-iron testing to see if a mixed set would be best for me. T150 looked like the way to go right off the bat. And again you're getting fit with the 4-iron (as well as the 7-iron) in a Titleist fitting to make sure ball speeds, heights, and gaps are ideal through your entire set. The T250 had potential but ultimately the T150 just went through the ground better for me. And with T250 I also felt I had to make adjustments more often to my natural swing. Same process as with the 7-iron, multiple shafts, and also tested the T350 as my 4-iron. But there would be no defeating T150 for me on this day.
T250-U and U-505 Utility
And finally on to the new utilities. One final big surprise was waiting for me. The T250-U 3 utility looked pretty much identical to the T250 3 iron. So it will blend perfectly with a set of T250 irons. And being smaller than the U-505 utility I assumed this would be my 3-iron. Nope.
The U-505 utility was higher, longer, and better for me. And U-505 also gave me better results on shots I didn't hit as well as I would have liked. In my opinion it's clearly the more forgiving utility of the two. It's incredibly easy to launch in the air and the wider sole was more beneficial for me with this lower lofted club.
Although it's a wider sole than T250-U it looks a bit narrower, sleaker than the previous gen U-505. The U-505 also had a lighter overall feel than the T250-U utility but at the same time U-505 gave me greater head awareness and felt more solid on good swings as well. And my smash-factor consistency with U-505 was 0.04 (the lower the better) so it has the potential to become my favorite club in the bag.
We tested different shafts in the U-505 once we knew this was the 3-utility I'd be playing. And ultimately we wound up the the Graphite Design AD-DI, or as Justin calls it "your normal shaft." There's something to be said about a fitter who knows your game. What I also liked a lot about the U-505 is knowing the variety of shots and versatility it will give me.
Certainly U-505 will be my club on long approaches. Nothing beats high and soft into the green. But the U-505 will also be a ball advancer for me because of its incredible distance. Ball speeds were insane. And I'll also use U-505 off the tee when driver is ill-advised, the overall control and forgiveness of U-505 is exceptional. This is undoubtedly a triple-thread club for me.
Final Thoughts
So what did I ultimately wind up with? The T150 4-iron through Gap with Project X Red 5.5 shafts and the U-505 3-utility with AD-DI 85 shaft. Groove is in the heart baby!
One of the big stories of the new T-Series irons is more consistent spin out of the rough. Titleist worked with Vokey on new grooves for the 2025 irons and Justin told me Titleist was looking at only a 10-percent reduction in spin out of the rough with the new irons. Obviously I didn't hit out of the rough at my fitting but I'll report back on this once I receive my set. As you saw on X and Instagram however the rain started coming down at the end of my fitting and I can tell you my spin in the rain was still pretty damn good. Downrange distances before the rain came and after the rain came were very similar.
And there you have it. This review has been a bit longer than most I write. But then again we covered six different clubs from the 2025 Titleist T-Series lineup. While nothing can take the place of a fitting, I hope you find a lot in this review that helps you decide on what new Titleist irons and utilities are best for your game. And as always happy to answer any and all questions all of you might have.
Titleist clearly went hell-bent all in to make new 2025 T-Series their best performing, best feeling, and best looking irons and utilities they've ever designed. And to say they succeeded would be a wild understatement. T-Series isn't merely a new Titleist release. It's a scorched earth Titleist flex.
Absolutely a fantastic review!
