As the most played iron on professional tours worldwide, the previous iteration of the Titleist T100 is undoubtedly a favorite amongst the better players in the game. I have been testing out the newest version of this incredibly successful iron to see what has changed and if it can maintain its spot amongst the best irons on the market.
In terms of the technology story, the main headlines here are the introduction of a new, more aggressive groove in the shorter irons of the set, while a muscle channel has been strategically placed within the longer irons to help increase peak height. Both of these changes have come as a direct result of feedback from the tour, with players craving lower flying, higher spinning short irons, and higher soft landing long irons. Titleist believes that the new long iron design will see more players staying in the T100 irons further up their set rather than requiring the use of a utility iron to help raise ball flight.
Looks-wise, truth be told, it is more of the same from Titleist here, which is a good thing. The T100 has been one of the classiest-looking irons in the game for a long time now, and they have been very careful not to tinker too much with a winning formula with the 2025 model. In fact, this was almost a demand from players when the design team sought feedback from the tour: “DO NOT change the look!” was the overwhelming response, and Titleist listened. In all honesty, you would do very well to distinguish this model from its predecessor with just a glance, both from the playing position and the ‘in the bag’ angle.
As before, the address position offers us minimal offset and a nice crisp, thin topline that screams precision and control.
Performance-wise, I would say ‘no surprises’ would sum up my testing experience well. I saw all of the characteristics that made the previous T100 model what it was, with just the merest hint of progression in terms of the short iron spin rates and higher flying long irons. This was exactly what Titleist was looking to achieve, so it is a job well done.
The deep, soft feel I have become familiar with thankfully remains, and the nice short blade length allows plenty of wiggle room in terms of shot shaping.
While the longer irons definitely do launch a fraction higher, I fear the Titleist hopes that players will stay in the T100 model more in the 4 and 3 iron area may be scuppered by the quality of one of its other new releases, the T250 and T250U, which are nothing short of outstanding in those lower lofts.
This year, the T100 has been made 1˚ stronger throughout the set (7-iron is now 33˚), which is somewhat contradictory to the goal of higher peak heights, but there is nothing to tie you to these lofts. I was in fact fitted to 2˚ weaker than standard which worked really nicely for me.
While I was looking forward to putting the new grooves to the test, in truth, I didn’t see any difference in spin rates between this model and either my current set or the previous T100. In normal test conditions, throughout the bag, my spin rates were exactly where they would normally be, and other situational testing didn’t indicate any huge leaps either. During my fitting with Titleist, for example, I was taken to the rough with both the T100 and my own gamer iron, the TaylorMade P7CB, to measure spin both from the rough and with water sprayed on the ball. In both instances, my spin rates didn’t change at all.
I very much enjoyed the new Variable Bounce Sole, which slides beautifully through the turf even for a steeper angle of attack player like myself, and it feels like it would have the versatility to perform well in a variety of ground conditions.
Overall, can I report a groundbreaking new technology or performance characteristic? No, I cannot. But when your starting point is at the upper end of excellence, change may well be a bad thing. The subtle tweaks Titleist has introduced in the 2025 T100 are probably all it required, and whether that is enough for you to want to upgrade your current T100 set is entirely up to you.
The Titleist T100 will be available for $1499/£1379 per 7-piece set (steel), $1599/£1479 per 7-piece set (graphite).
