The 2021 Titleist T100 and T100S irons are some of the finest players irons in the game. Shocking levels of forgiveness in an iron this compact and attractive. Great feel. T100S gives more fitting options.
The Titleist T100 is the #1 iron on Tour, and it’s not difficult to understand why. From their looks to the impact feel, they have all the subjective elements that better players crave. When you add in the fact that Titleist keeps raising the bar for forgiveness in a players iron, it makes the T100 a no-brainer choice for the best golfers in the world.
At address, the biggest change from the original T100 is the finish. The 2021 version has a brushed chrome finish that will reduce glare. Beyond that, not much changed because nothing needed to change. The T100 remains a near-perfect players iron: thin top line, minimal offset, and compact blade length.
There are some progressive elements to the design of the T100, but they’re very subtle. As you move from the long irons to the scoring irons, the blade gets slightly shorter. There’s also less offset, which is standard. Finally, there’s a very minimal rounding of the leading edge as the loft increases.
What has improved markedly is the look of the T100 irons in the bag. I liked the original T100, but the new version is much cleaner. Part of that comes from the aforementioned brushed chrome finish, which gives the head a more modern look. There’s also a lot less going on in the 2021 T100 – just a simple cavity and very minimal branding. From every angle, the 2021 Titleist T100 irons are gorgeous.
Sound & Feel
Titleist made a significant effort to improve the feel of the T200 [review HERE] and T300 irons [review HERE], and they succeeded. However, neither of those irons feels as sweet as the T100. On center, the T100 is soft and crisp, like a ripe apple. It’s an addictive feeling, and I suspect I annoyed my fitter with the number of shots I hit with this club.
Feedback from the T100 irons is clear but not punishing. There’s no sting or shock to a mishit, but you’ll get a clear picture of whether the shot was struck on the heel, toe, or bottom groove.
Beautiful looks and satisfying feel are great, but plenty of irons offer that. Where the T100 sets itself apart is by offering more forgiveness than almost anything else at this size.
This forgiveness is driven by the use of denser D18 tungsten and a dual cavity construction. Titleist is able to put the weight where it will create stability and position the CG for optimal launch and spin.
Tech talk aside, what you’re going to see on the course is that the T100 is more than happy to take a thin shot and throw it onto a playable trajectory. You can hit the ball off-center and still retain excellent ball speed and distance. Slight heel or toe strikes will hold their line rather than careening toward the woods.
All this forgiveness comes without the loss of workability. Titleist actually raised the spin in the 4-7 irons slightly to improve trajectory, stopping power, and shot shaping. This is a very minor tweak – the T100 can still go – but it’s something that the high level players will likely notice in head-to-head comparisons.
Now let’s talk about the T100 vs the T100S. The T100S is almost the exact same iron at the T100 but with lofts that are two degrees stronger throughout the set. Titleist stresses that the T100S is designed stronger not simply bent to this spec. It also has a Muscle Channel meant to add speed and launch. The T100S has loft specs that are very similar to the T200, and, for me, it produced almost as much distance. I found it about half a club longer than the T100.
It’s very important to note that stronger lofts will not always produce more distance. For me, the T100S is clearly longer 6-GW. I would see slightly less of a gap in the 5I. In the 4I the gap would be small, perhaps insignificant, and the 19 degree 3I (T100S) might be shorter than the 21 degree (T100). All this is because I tend to hit the ball a little lower, and I have good-not-great speed. You should work with your fitter to determine whether the T100 or T100S will produce the best, longest, most consistent shots for your swing.
The 2021 Titleist T100 irons are easily one of my favorite sets of the year. Titleist kept everything I liked about the previous version, such as the satisfying feel, while improving the look and performance. For the player that wants to play T100 but needs more distance, the T100S is a perfect fit.
