Tour pros aren’t that different from the players in your weekly foursome. They tinker. They try new clubs. They chase better performance in every swing.

The one thing that hasn’t changed: Titleist has been the most played iron brand on the PGA TOUR for 11 straight seasons.

But sustained success doesn’t happen by chance.

Shaped by Tour Feedback

Throughout the development of the latest T100, our team worked side-by-side with Tour pros to test, tweak, and refine every millimeter of every iron.

From topline to turf interaction, every detail of T100 has been influenced by player insight. If it doesn’t pass their eye test, it’s back to the drawing board. If the spin rates are a fraction off, it gets reworked until it meets the highest standard. It’s a feedback loop that starts with Tour pros and ends in the hands of golfers everywhere who are chasing their own version of elite performance.

As part of the fourth generation of T-Series irons, the new T100 irons are a culmination of what this feedback loop can deliver. They retain key attributes that players love—like exceptional feel and a compact look—while refining or adding new features based on notes from players like Ludvig Aberg, Jordan Spieth, Justin Thomas, and Cameron Young—like the new Progressive Groove Design and improved Variable Bounce Sole.

Beyond iterative, player-driven improvements, this generation of T-Series marks an even bigger leap in performance. And it’s all thanks to several new technologies that make this modern Tour iron unlike anything you’ve played before.

Validated By The World’s Best

You might not expect a forged Tour iron to pack much tech, but T100 rewrites this idea. For 2025, Titleist is introducing several new features designed to elevate performance and improve consistency—even for the game’s best ball-strikers. This includes a new Muscle Channel in the long irons and a new Progressive Groove Design.

But before any new Titleist innovation can be approved, it must prove itself in the hands of the world’s best. Once T100 is put to the test and earns their trust, it’s ready to be released to the world.

Proven Performance Through the Full Lineup

The insights we gather from the game’s best don’t stop at T100—they shape the entire T-Series lineup.

This means the same feedback that helps a Tour pro control a knockdown shot toward a tucked pin is also helping your T250 7-iron penetrate through a two-club wind. The refined Variable Bounce Sole that gives T100 exceptional turf interaction? It’s part of what makes T350 feel buttery smooth through impact—whether you’re thinking about “turf interaction "or not.

So, even if you’re not shaping shots on command and chasing major championships, you’re still benefitting from one of the most sophisticated R&D processes in golf. And whether you’re in need of extra distance, forgiveness, launch—or all of the above—there’s a T-Series iron built to suit your swing.

Tour-inspired doesn’t mean Tour-exclusive. It means every player—regardless of handicap—can play our irons with the confidence that they have been validated at the highest level.
