2025 Titleist T100 Irons Review

50 Words or Less

The 2025 Titleist T100 irons carry forward the beauty and precision of previous generations but with enhanced forgiveness.  New fitting technology makes Titleist iron fittings among the best available.  Easy to see why T100 has been the #1 iron on Tour.

Introduction

Since their introduction, the Titleist T100 irons have been the most-played iron model on the PGA Tour.  And since we all dream of playing like the pros, the T100 is also the Titleist iron that most recreational golfers want in their bag.  I’m certainly one of those golfers, so when I had the opportunity to go through a full fitting for the new Titleist T-Series irons, I was hoping my ball striking would earn my fitter’s approval to bag the 2025 Titleist T100 irons.

Looks

Titleist took what I called “one of the cleanest looking sets of players irons” and made it even more minimalist and timeless.  The 2025 Titleist T100 irons look absolutely sensational from every angle and will inspire nothing but envy when your friends see them in your bag.

In the bag, your eye is immediately drawn to the “Titleist” logo.  “T100” branding is tucked into a cavity that’s even more subdued than its predecessor’s.  This is topped with a matte finish that’s shared by the entire 2025 Titleist T-Series iron family.

At address, this set shares all the characteristics that players loved about the previous T100 models.  The top line is thin, and there’s minimal offset.  What stands out most to me is the compact blade length – these look like surgical instruments, ready to produce precise shots.

Above, you can see the 2025 Titleist T100 (right) next to the T150 (left, review HERE).  Per Titleist, the T150 has a “slightly larger head size” than the T100.  My fitter told me that the blade is 0.5mm longer, and both irons have the same offset specs.  The top line of the T150 is thicker, but this is one of those situations where the T150 suffers because of the comparison.  On its own, the T150 is gorgeous and thin, but it’s always compared to arguably the best looking iron in golf.

Sound & Feel

During my fitting, I made copious notes about the feel of all the new Titleist irons.  The note taking continued once I got the clubs home for testing.  After all that effort, I had to laugh when I pulled up my review of the 2023 T100 irons [find it HERE] and found all the same words.  I guess Titleist knows not to mess with a good thing.

“Soft and crisp” remain the words that appeared most often when I was writing about the sound and feel of the 2025 Titleist T100 irons.  To me, these irons hit the perfect sweet spot – soft but not mushy, responsive but not firm.  Every strike feels solid and heavy, but the best ones have that hint of brightness and speed.  This slight “bonus” complements the precise feedback on strike location.

The sound amplifies the traditional impact sensation of the 2025 Titleist T100 irons.  It’s 90% quiet “thud” with 10% “click”.  I hesitate to use that word as it tends to hint at an iron that’s firm, hard, or thin in its sound.  The 2025 Titleist T100 is none of those things, but the sound has more life than some other forged irons.

Titleist T-Series Iron Fitting

Titleist has long been a leader in custom fitting, but they’re taking it to an even higher level with the 2025 T-Series.  They’ve given their fitters two impressive new tools: a SureFit-style hosel on the fitting irons and the ability to change head weights.  With the new fitting system, players can test irons up to four degrees upright and as much as two degrees flat.  They can also remove a degree of loft or add up to two.  In the past, the player and fitter could only make an educated guess about these types of adjustments before ordering their set; now they can know for sure that they have the fitting perfected.

While the tools have improved, the core of Titleist’s iron fitting philosophy hasn’t changed.  They’re focused on three Ds – distance, dispersion, and descent angle.  While distance is clearly important, it’s meaningless if your shots don’t find their target or land softly when they get there.  Titleist’s approach is also extremely scientific.  Every Titleist fitter knows the key numbers that a player needs to achieve with each iron.

Fitting each iron individually is why 90% of Titleist’s iron fittings end up with blended or combo sets (a set of irons that combines multiple models).  A player might be able to hit their required numbers with a T250 in the 7I through PW, but they can’t create enough speed or launch at the 6I.  That’s when the fitter transitions the player to the T350 [full review of the T350 HERE].  You might even see three different models in one bag – all that matters is getting the right performance.

Titleist has made combo sets even better with the 2025 T-Series family by creating a unified look.  They rectified the one major flaw in the 2023 T-Series by giving every iron the same matte finish.  Just looking at the soles, you wouldn’t have any idea that the bag below includes three different iron models.  Additionally, they made each model look more similar in the bag and at address.  Only the T350 has a different offset spec, and the branding is the same across the board.

Performance

It would be easy to look at the 2025 Titleist T100 irons and think it’s just another basic cavity back.  But under that minimalist veneer, Titleist has packed in an impressive amount of technology.  Walking away from my fitting, I wrote, “Titleist took the iron my heart wanted and made it playable.”

The technologies that fuel the forgiveness of the 2025 Titleist T100 irons are the Variable Face Thickness (VFT), Split High-Density Tungsten, and a Progressive Dual-Cavity Construction.  VFT helps to keep the ball speed and launch consistent across the face, but the tungsten is what every Titleist fitter wanted to talk about.  They were all shocked by how much tungsten Titleist’s engineers packed into the heel and toe to make this club more stable on mishits.

All this tech helps the 2025 Titleist T100 irons to be among the leaders in forgiveness relative to their size.  This is not a club for the high handicapper – those players will want the T250 and T350 – but I was consistently surprised at how far and straight my mishits went.  My good-not-great strikes ended up on the green, and my bad swings still left me with reasonable up-and-down chances.

Despite all this tech, the 2025 Titleist T100 irons are still precision instruments.  Their compact size makes me stand over the ball and think of creating beautiful, specific shots rather than just blasting it forward.  Shot making is why I play golf.  It’s the thing that keeps me on the range, and it’s the part of the game that lives in my head after a round is over.  From low to high, cuts to draws, the T100 irons can bring any ball flight to life.

Speaking of ball flight, Titleist made a couple changes to improve that in the newest T100 irons.  Throughout the set, the irons feature different grooves.  In the mid and short irons, the grooves are “more aggressive” to give players the confidence to attack the flag from the rough and in wet conditions.  By comparison, the grooves in the longer irons are less aggressive to promote more distance.  The long irons, specifically the 3I and 4I, also got a new muscle channel design (similar to what’s seen in the T150) to create a lower CG and promote higher launch.

Finally, a pretty standard spec change was made to the 2025 Titleist T100 irons but for interesting reasons.  Throughout the set, the lofts are one degree stronger than the 2023 version.  We see this throughout the industry as OEMs seek to win fittings by making their irons “longer”.  According to the Titleist fitters and reps I spoke with, that wasn’t the purpose here.  This change was done to offer slightly more distance to their LPGA players who love this model.  They also noted that PGA Tour players who don’t want to change their lofts can bend the set one degree weak and add some bounce, a change that many welcome.

Conclusion

It should be clear that I love the 2025 Titleist T100 irons, but was my ball striking worthy of bagging these beauties?  I’m pleased to report that the answer is “Yes,” my fitter put me in the T100 from 7-PW with the T150 in the 4-6 irons.  If you want to bag an iron that will turn heads with its looks and its performance, try the 2025 Titleist T100 irons for yourself.
