FIRST IMPRESSIONS: The new Titleist T-Series range is a phenomenal looking club, from the brand new T100s through to the T350s.

At first look, the new T-Series irons reinforce Titleist’s design philosophy of clean, compact shaping. Each model progresses logically in size: the T100 and T150 remain traditional in profile, while the T250 and T350 introduce more topline and sole width without straying too far from a player’s silhouette. The transitions are deliberate, which makes blending sets straightforward.

In testing, the standout feature was the stability of ball flight across the family. The T100 delivered the expected precision – flatter trajectory windows with tight dispersion. The T150 introduced a touch more ball speed and height, with descent angles that clearly support green-holding. Moving to the T250, there’s a measurable increase in launch and carry, yet spin rates stayed consistent enough to maintain distance control.

Titleist’s fitting leader, Jonathan Law, can’t speak highly enough of the new 250 Launch Spec, and this tester agrees.

“The 250 Launch Spec is an outstanding product. It’s got all the assistance of a 250 with the thin L-Cup face, tungsten in the toe and the heel, and the max impact support for the face.

“It’s got traditional loft. So, the seven irons are the same loft as an MB, CB seven iron at 35-degrees.”

The T350 provided the highest ball speeds of the group, but what impressed most was the forgiveness on off-centre strikes. Retained ball speed and dispersion patterns indicate that the hollow-body design and tungsten weighting are functioning as intended.

Feel was differentiated but not disjointed. The forged T100 and T150 offered the softest, most responsive impact, while the T250 and T350 leaned firmer and more energetic, consistent with their construction. None felt disconnected from the brand’s overall “solid through impact” identity.

Overall, first impressions indicate Titleist have tightened the performance gaps between the four models. Each delivers on its intended role – precision, speed, distance, forgiveness – while maintaining a consistent family DNA.

HOW IT PERFORMED: On course and range testing confirmed the clear separation between the four models. The T100 was the most precise, with consistent spin windows and dispersion patterns that rewarded centred strikes. Ball speeds were moderate but entirely predictable, which is exactly what better players expect.

The T150 added noticeable launch and speed without a major trade-off in control, and for this reason, it was my iron of choice. Shots peaked higher and landed steeper, making it easier to hold firm greens. The extra forgiveness was subtle but evident when contact drifted slightly from the centre.

The T250 showed the biggest performance jump. Ball speed gains were immediate, particularly in the long irons, and carry distances increased accordingly. Launch stayed playable and spin rates proved stable enough to prevent shots from running out. For golfers seeking a genuine distance iron without severe gapping issues, the T250 met that brief.

The T350 was the most powerful and forgiving. Launch was effortless, and even heel or toe strikes carried well past expectations. Distance consistency stood out most – poor contact rarely lost more than a few metres. While shot shaping was limited compared to the T100/150, the forgiveness and ease of use more than compensated.

TITLEIST SAYS: The new T-Series family includes the next generation T100, T150 and T350 irons, along with the brand-new T250 – Titleist’s newest player’s distance iron – plus the high-launching T250 Launch Spec model, which fits an entirely new player profile within the platform. Each iron is designed around specific performance characteristics, yet it is built to blend seamlessly into the bag.

As the most played iron brand on the PGA TOUR for 11 straight seasons and counting, Titleist draws on feedback from the game’s best ball-strikers, discerning amateurs and its worldwide network of fitters. That insight drove three design objectives for the new T-Series: increasing long iron launch, tightening mid- and short-iron spin consistency, and improving overall carry distance consistency throughout the bag. Each iron is built to deliver specific distances within a consistent flight window, with more repeatability across the set.

Titleist’s 3 D’s – distance control, dispersion and angle of descent – guide both the fitting process and product development, with engineers maximising these performance parameters in every design. The result is the best-performing T-Series lineup yet.

New T-Series irons are available now at Titleist fitting locations and in golf shops worldwide. Golfers can find a fitting near them by visiting Titleist.com.au.
