If there’s a sound more satisfying than a flushed iron shot, it might be the collective sigh of relief from the folks at Titleist this week.
After years of tinkering, testing, and enough player feedback to fill a library, the brand-new Titleist T-Series Irons have officially stepped into the arena—making their much-anticipated debut at the PGA TOUR’s Charles Schwab Challenge and the DP World Tour’s Soudal Open.
For over a decade now, Titleist has led the charge as the most trusted iron brand on both major tours.
And in typical Titleist fashion, they’re not just dropping new clubs and hoping for the best. No, sir—they’re handing them over to the best players in the world and letting the results speak for themselves.
Over the next three days of practice, Titleist tour reps will be in full-on “mad scientist” mode, working with players to fine-tune setups and fit them into the new T100, T150, T250, and T350 models.
The T250•U and U•505 utility irons are also breaking cover this week, promising a feast for shotmakers in Texas and Belgium alike.
The Proving Ground Begins Thursday

Thursday marks the official start of on-course competition for these new sticks—a vital step in Titleist’s meticulous tour seeding and validation process. And believe me, these irons didn’t just fall out of a vending machine.
“It’s years of research, player feedback, player testing,” said JJ Van Wezenbeeck, Titleist’s Senior Director of Club Promotions. “To bring the product out, see it tested on the golf course during a tournament week and prove itself – it’s super exciting to see all that finally come to fruition.”
Henley Knows What He Wants—And Gets It
Enter Russell Henley, who, if you believe in stats, is one of the most clinical ball-strikers in golf.
He’s currently top five on the PGA TOUR in both Greens in Regulation and Proximity—fancy numbers for “he’s peppering flags on the regular.”
Henley knows his way around a set of irons, and his thoughts on testing the Titleist T-Series Irons are telling.
“[With] 9-iron, what I want to do is hit one really hard and be able to put it way up in the air,” he said. “And then I also want to [have the ability] to take a lot of speed off and take spin off, but I still want it to land soft.”
When it comes to the longer irons, Henley’s not looking to balloon shots into the next postcode. “I want to be able to get that ball up in the air, but I don’t want to get it up in the air with too much spin,” he added.
“Golf is getting to be more and more specific… the more every shot needs to be approached a little bit differently and be attacked in a different way.”
Henley bagged a T200 (4-iron) and T100 (5-9) combo set en route to his win at the Arnold Palmer Invitational in March, proving that the Titleist T-Series irons aren’t just for showroom glances—they’re built to win.
A Legacy Built on Trust and Turf

Let’s not forget: Titleist irons have long been the go-to choice of the game’s elite.
For 11 consecutive seasons—and 20 of the last 21—Titleist has been the most played iron brand on the PGA TOUR. Over on the DP World Tour? That streak runs to 16 straight seasons.
The T100 model, in particular, has been the single most used iron on the PGA TOUR since 2019, which in golf terms is practically a dynasty.
As the Titleist T-Series Irons begin their journey in the hands of golf’s best this week, one thing’s clear—these aren’t just clubs.
They’re a culmination of countless hours of R&D, player insight, and pure golfing heritage.
Stay tuned to titleist.co.uk and Titleist’s social channels for real-time updates, testing insights, and maybe even a few tales of irons turned into trophies.
Because if history’s anything to go by, these Titleist beauties won’t just be tested—they’ll be trusted.
