The 2025 Titleist T-Series Irons Are Here

The Titleist T-Series is a workhorse in the iron category. From offering models designed for the best ball strikers in the world to models that are intended to make the game fun for golfers of all swing speeds, the T-Series has something for everyone.

For the newest series, Titleist is doing what they’ve done for generations of irons going back to the AP-line, and that is to evaluate what is working (and what's not) and tweak the designs to uncover every possible advantage.

Four + One Models to choose from

As with the previous generation T-Series irons, there are four models to choose from, plus one extra model variation thrown in for good measure.

The models are the T100, T150, T250, and T350, with each design tuned to help golfers find their best 3D fit: Distance, Dispersion, and Descent Angle. It's this fitting philosophy that defines the Titleist process, which is also why, to go along with the new irons, they have developed a new fitting tool that is even more precise.

The extra variation is the new T250*(star) aka the Launch Spec. This model is spec'd with lofts almost a full club weaker than the standard T250, and with lighter head weights to help produce higher launch and spin for golfers who need help with carry distance, apex height, and stopping power.

The Nitty Gritty

T100

The directive with the new T100 is simple - dont mess with a good thing, simply refine where possible to improve performance and feel. For internals, the T100 utilizes the tungsten cavity to increase MOI but has more mass behind the center of the face for a more dense and solid feel.

The T100 also now come with a muscle channel in the longer irons (technology that debuted in the T150s) to improve ball speed and launch condition consistency in the longer irons. The lofts have also been made 1-degree stronger to better gap with other irons in the series.

One last thing, and this is a doozy.

Titleist have completely overhauled their groove design to better maintain spin rates out of the rough and in wet conditions, meaning the potential of thousands more RPM to better control shots from the rough.

The main design goals with T100 were in alignment with our priorities across the entire lineup: improve long-iron launch and carry distance consistency," Marni Ines, Titleist’s Director of Iron Development said. "T100 has a new muscle channel in the 3- and 4-irons to raise launch and peak height, and its new Variable Face Thickness, lower CG and progressive groove design are all really working to tighten up front-to-back distance dispersion.

T150

Sitting between the T100 and the new T250, the T150 offers a combination of higher launch and lower spin to stretch distance gapping and add forgiveness.

Like the T100 the new T150 features updated internals for more forgiveness, a thicker area behind the center of the face for better feel, and the improved groove design. For golfer needing higher launch, lower spin, and a bit more ball speed without going to a hollow body iron - this one is for you.

T250 and T350

This is where things get interesting. The T250 and T350 are the models with the biggest changes made to the platform. It should also be noted that the T200 name is now dead and thats where the T250 comes in.

With the new T250 and T350, golfers can finally say goodbye to the composite cavity cover and hello to a full metal hollow body construction. This design and manufacturing technique allows for better feel and performance because each iron has less parts that go into the final construction. Now let me be clear, it's not that the previous generations of the T200 were bad, in fact they were used for all kinda of tour wins, including a major, but, its kinda like when Chevy updated the Corvette to a mid engine design. Yeah older ones were cool and drove nice, but the new mid-engine Corvette is a whole other animal.

The re-engineered bodies also create a more solid structure and allows the internal max impact technology to fit tighter against the new forged L face. But even with all this tech, the soles have been designed to provide enhanced playability for almost any lie, and from a shaping perspective both irons now have a much more progressive blade length (overall size from the toe to the heel) so the mid irons flow better into the wedges.

As for the previously mentioned T250* (Launch Spec), this model features all of the same design components as the T250 but with weaker lofts, and lighter head weights. The origin of this additional model was based on the needs of the many high level and developing junior golfers that Titleist saw through their network of fitters who needed something that offered a lighter package and more spin, but developed into an iron meant for any golfer that needs more height and stopping power.

New Fitting Capabilities

To go along with the new T-Series tech, the next biggest upgrade has nothing to do with final performance and everything to do with fitting, because the better and more precise the fit, the better the end results. Titleist has completely upgraded their sure-fit hosel system to allow for more lie and loft ranges, going from 2-degrees flat to 4-degrees upright, and 2-degrees weak to 1-degree strong. There is also a new back weight in the head that can be interchanged during the fitting process to help fit golfers needing overlength clubs, so the fitted club feels as close as possible to the final product.

This fitting upgrade will be available to all Titleist fitting accounts.

Price and Availability

Like with the previous generation, the T-Series irons are priced equally across the board to make for easy combo-ing without golfers having to worry about price; $1500 for a 7-piece set in steel and $1600 for a 7-piece set in graphite.
