What we say...
One of four golf irons in the revamped T-Series range for 2021, the T100 iron is a modern players' models aimed at better golfers and the most played on the PGA Tour.
Titleist's T100 iron has been sharpened and modernised and, as with the other models in the T-Series, built around three key Ds – Distance, Dispersion and Descent Angle.

Of course when you're improving the most played iron in the game it's vital to get the views of some of the best iron players in the world and Titleist have done just that.
Jordan Spieth, Will Zalatoris, Sungjae Im, Cameron Smith, Garrick Higgo and Jessica Korda, have all been involved in the process which has seen the T100 spend more than 1,000 hours in Titleist's players' hands.
Designed to provide precise control and unrivalled feel, the T100 is a fully forged dual cavity iron that looks like a blade at address thanks to its thin top line and minimal offset.
The new variable bounce design is Titleist's "best-feeling ever" with less bounce on the heel and more on the toe for improved turf interaction and feel, something three-time Major champion Jordan Spieth was particularly impressed by.
Use of more dense D18 tungsten weights and the same 2000º brazing process used in aerospace construction has helped to eliminate weld points and create an even more precise CG placement for improved MOI.
The new face features a continuous cradle construction that creates a seamless striking surface and more uniform leading edge. The 4i-7i faces were redesigned to provide slightly more spin for improved shot-shaping and stopping power.
We love the new brushed chrome finish, which ensures glare will never be a problem.
The T100 is joined in the T-Series by the T100S, T200 and T300.

The T100S is Titleist's "faster tour iron" and two-degrees stronger than the T100. The T200 is a players' distance iron, Titleist's most advanced ever, and represents the biggest shift within the series, combining sleek looks with impressive distance.
The T300 is Titleist's ultimate game-improvement iron, the cavity-back model designed to be high, long and forgiving, using 40 per cent more tungsten than its predecessor.

Titleist T100 irons tech
New Tour-Designed Sole: By working with select tour professionals and in collaboration with the Vokey Design wedge team, Titleist engineers developed a new variable bounce design - less bounce in the heel and more bounce in the toe - that provides better turf interaction and improved feel. The design has been overwhelmingly validated by some of the world’s best ball strikers.
Better Tungsten for Better Balance: Utilising a denser version of tungsten (D18) weights in the heel and toe of the three to seven irons for greater mass efficiency, and a brazing process used in aerospace construction, Titleist engineers were able to eliminate weld points and be even more precise with CG placement and produce high MOI in a ‘player’s iron.’
Refined for Greater Consistency: The new T100 face features a continuous cradle construction that creates a seamless striking surface and more uniform leading edge. A proven, fully forged, dual cavity supports the face construction. The 3-iron to 7-iron faces were redesigned to impart slightly more spin for improved shot-shaping and increased control. The 8-iron to Pitching Wedge are forged with one-piece 1025 carbon steel.

What the pros say about the Titleist T100 irons
Three-time Major champion Jordan Spieth put T100 4-9 irons in play at the Open Championship, where he finished runner-up after four consecutive rounds in the 60s at Royal St George's.
“The sole just glides through the ground so nicely," Spieth said. "With the added bounce off the toe and the reduced bounce in the heel similar to the wedges that we have on those grinds, it just allows for some consistency when you get a little bit off.

"The idea that you can be on uneven lies and have it kind of make up for that, and then if you get in the rough and have it not drag as much, but instead slide through just as easily, that’s where we see the improvement in these irons.
“I don’t understand why you’d play any other iron to be honest. I joke around, ‘I’m not good enough to play the blades,’ but in reality, I think we’re just being smarter. I think we’re just like, ‘Oh, we can actually hit every shot that a blade can hit.’ But that chance that we mishit them – which we’re going to mishit a few shots in a round, even in a great round, the idea that it does carry that bunker and you make birdie on a hole where someone has to get up and down for par – I mean, it could be the difference in a tournament.”
LPGA star Jessica Korda was one of the first players to hit the final T-Series prototypes during a trip to the Titleist Performance Institute in early 2021. She put her new T200 4-iron and T100 (5-9) irons in the bag at the Marathon Classic.
“They’re just really pure. It’s like I’m hitting blades, but you’re not. I loved how solid they felt. The height on them is incredible. It’s exactly what I’m looking for, especially in the longer irons.
“The consistency is what I look for. Because when I’m standing over the ball and I need this thing to travel a number that I have in my head, and I can rely on that and just be like, just make a good swing, it takes so much of the guesswork out of it and it makes you commit to the shot more.
"I don’t change often. It has to beat what I have, and this is really nice. To be even better, to help me hold greens like I need to with the longer irons, especially going into par fives, it’s really, really nice.”
What Titleist say about the T100 irons
Marni Ines, Director of Titleist Irons Development: “T-Series irons are designed to provide precise control for any player who wants to score lower. From form to feel to function, every aspect of these irons is crafted towards the golfer being consistent from their first shot to their last throughout every round.
"Whether it is the T100, T100S, T200 or T300, every iron is individually engineered to help the golfer deliver a strike where they can see and feel pure performance.
“What sets these irons apart from the competition is the precision and feel they provide the golfer. Irons are scoring clubs and it is important to the T100 player to hit their number and hit it more consistently.
"With that as a priority, we took the best performing iron in the game and made it better by adding high density tungsten, which is the engine of our iron designs. It allows us to put the CG where it needs to be, provides stability and builds up MOI.
"The way this new T100 is engineered also allows us to keep that blade-like profile these golfers desire which is so important for confidence when looking down at their club.”
Josh Talge, Vice President of Golf Club Marketing for Titleist, said: “The new T-Series irons represent another step forward in Titleist iron design and technology. With these new irons, across the board, every detail matters.
"They provide the best precision and performance in their respective iron category with stunning aesthetics and feel. Golfers don’t buy an iron ‘line’, they want specialisation, and that’s what each of these models offer.”
