After a loud Tour launch in May and a PGA Tour win, Titleist is ready to pull the curtain back on its fourth-generation T-Series lineup. As teased during Tour seeding, three of the four models (T100, T150 and T350) are all returning to the lineup, while the new T250 replaces the T200 model as the players’ distance option in the family. But Titleist is also introducing a new model, the T250 Launch Spec, for players who need the speed of the T250 but more loft to get the ball airborne.
Several PGA Tour pros have already transitioned to the new T-Series irons, including Aldrich Potgieter, who earned the first worldwide win for the line at the Rocket Classic a couple of weeks ago. Titleist irons have been the No. 1 choice on the PGA Tour for 11 consecutive seasons and counting.
Below are seven key things to note about the new Titleist T-Series launch
1. SureFit fitting heads
Titleist possibly has the most comprehensive iron fitting in the game because not only do they fit you for a 7-iron, but they also fit you for a 5-iron and longer irons if applicable. The argument is that if you can hit a 7-iron with one setup, you can hit the 9-iron, but not necessarily the 5-iron. Titleist fits your irons to optimise the “3 Ds”: Distance Control — ensuring consistent 5 mph ball speed gaps between clubs; Dispersion Control — tightening your shot accuracy; and Descent Angle — delivering consistent trajectories to help shots hold firm on greens. This philosophy explains why 80 per cent of Titleist Tour players use at least one model in their iron set.
With the new T-Series platform, it’s easier than ever, thanks to the new SureFit fitting heads. SureFit may sound familiar, as it’s what Titleist calls their adjustable hosel for metalwoods, and now it has been adapted to their fitting for iron heads, working similarly with two rotating cogs.
With the SureFit irons, fitters can now take the same shaft and head combination between 2 degrees flat and 4 degrees upright, or 1 degree strong and 2 degrees weak — in seconds. They also feature an adjustable weight that allows for the removal of 6 grams of weight for players who need it, either due to a longer shaft length or a preference for a lighter swingweight. In total, there are 28 possible loft/lie combinations without the need to bend anything or switch heads.
2. Stronger lofts for T100
Having adjustable fitting heads is going to be key because Titleist made the new T100 irons 1 degree stronger lofted across the set from each of the previous three generations. This is far from a case of “loft-jacking,” though. The change to the standard spec was made because feedback from the PGA Tour was that the T100 irons needed more bounce. On the LPGA Tour, Titleist saw many players preferring the more compact T100 (and previous generation T100S), but required to bend them closer to the T150 lofts to achieve the desired carry distances. With T100 starting a degree stronger, players can now weaken them to the previous standard spec or more to get more bounce or leave lofts as is, or even strengthen them to get extra ball speed.
3. New tech under the hood
Compared to the previous generation, the look of the T100 and T150 hasn’t changed much, but the real advancements are concealed in the body of the iron. Once again, Titleist is using high-density tungsten weighting low in the head, split across the heel and toe, to add stability. However, there is 5-20 per cent more iron in each model to maximise inertia.
With the aim of the new T-Series to help players launch it higher, a new muscle channel sits in between the tungsten weights in the 3- and 4-irons of the T100 and the 3- through 7-irons in the T150. Both the T100 and T150 3-7-irons feature a new variable face technology to combine with the improved muscle channel to produce faster ball speed and help with proper gapping in the long- and mid-irons. Additionally, the blade length of T150 was increased by one millimetre. Initially, when T150 was created in the prior generation, only the topline and sole were thickened from T100.
4. New grooves
Titleist makes most of its R&D decisions based on Tour feedback and one of the things requested by DP World Tour players was additional spin out of the rough and wet conditions. The initial thought was to try the same grooves in Vokey wedges in the T100, but they found that that wasn’t necessarily a good thing for long irons and they actually spun too much. For the new T-Series, the mid- and short-irons use a new progressive, steeper-walled U-groove to help performance out of the rough. In the T100, the new groove is used in the 7-PW while other sets use it in shorter irons, depending on loft.
5. T250 and T350’s new look for blendability
The most radical cosmetic changes are reserved for the new T250 and T350, which now feature a new all-steel construction as opposed to the plastic badging that concealed the backs of the previous generation. The new look now matches the rest of the line, making it easier to blend sets. The T250 has been completely redesigned, resulting in the name change and a slightly larger profile — 1.5 mm longer blade length — but not one that will put off any previous T200 users. Both irons feature new variable thickness face designs with the T250 having a V-taper design while T350 has a multi-zone taper L face. With the CG moved lower to help with launch, the face designs help retain ball speed on lower strikes.
6. Max Impact technology
The key technological advancement in the new T250 and T350 is the addition of a new Max Impact core. With the Max Impact Core, Titleist aimed to increase ball speed retention across the face. Using the analogy of the face as a trampoline, Titleist sought to determine how to drop a ball on different parts of the trampoline and have it bounce to the same height. After testing different materials to try and tune the face properly, they found that a urethane polymer, similar to the material in a golf ball, underneath the face allowed it to have the same spring-like effect in the centre and off-centre.
7. T250 Launch Spec
With the newest release of the T-Series also comes a new fifth model to the lineup. The T250 Launch Spec is the same construction as the T250, but offers a 6-gram lighter headweight and 4-4.5 degree weaker lofts across the set with four-degree gaps off a 35-degree 7-iron, matching the 620 CB and MB irons. Titleist identified an opportunity in the lineup to cater to moderate swing speed players who require more launch and struggle to achieve the 3 D’s without additional support. A player could also take advantage of the T250’s speed, but in a more traditional loft package by going with the T250 Launch Spec. With custom options of plus or minus 2 degrees remaining, a player could now be fit into the T250 shape with a 7-iron loft anywhere between 28.5 and 37 degrees.
Final Thoughts
Over the years, Titleist has had a history of being a brand only for better players, but with the new T250, T250 Launch Spec, and T350, it’s making a serious statement that it can compete with other leading manufacturers for supremacy in the overall irons market. The T250 Launch Spec is specifically going to be a game-changer that many better players may even find beneficial to their game. There’s a reason so many Tour pros use Titleist irons and with this latest release, don’t be surprised if you see more flock to the newest T-Series after the offseason.
Titleist’s new 2025 T-Series irons are available for fittings and pre-orders starting Thursday, July 10 and will arrive at retail locations on Thursday, August 21. Each model will cost €245 per club, and a seven-piece set will cost €1,699 for steel shafts and €1,799 for graphite shafts.
