2021 Titleist T100 & T100S Irons Review

50 Words or Less

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.

  1. Matt, how do these compare forgiveness-wise to the apex tcb?

    • Matt Saternus


      It’s very close. I couldn’t give the nod one way or the other without a lot of head to head testing.



  2. Great review, Matt. I hit T100 for the first time this weekend and absolutely loved them. Looking at these, Apex TCB, and ZX7 to replace my Z785 next year. Any thoughts on how the T100/T100s compare to the Z785?


    • Matt Saternus


      They’re all in the same range. I think the ZX7 is nice step up from the Z785, but there’s not going to be a world of objective difference between any of them, at least not one that applies to every golfer.



  3. Justin Oshinsky

    T100 vs 0311T in terms of forgiveness for these smaller profile heads?

  4. Hey Matt I’m pretty much sold on the zx7 irons but the t100’s are so nice too. I found the zx7 to still be fairly forgiving. How would the t100s compare in the forgiveness department to the zx7. Thanks for all you do!

  5. Great write up as usual, thank you! I’m very interested in upgrading to these but am also strongly considering the Srixon ZX7. In both reviews you raved about forgiveness. My I ask, in your opinion, which one offers more help on a miss hit and which you prefer in general?
    Thanks again!

    • Matt Saternus


      They’re too close to say anything without a lot of head to head testing. In terms of preference, I think I like the T100 just a little better.


  6. Matt,

    I enjoy your reviews and this was another good one. Wondering if you could speak to which iron gave you better numbers for your game between the T100 and Callaway X-Forged CB? Do you prefer one of them over the other?


    • Matt Saternus


      I don’t have head to head numbers for those irons, but I prefer the T100. Both are good, but something about the T100 really resonates with me.



  7. Which golfers should use the T100 vs. T200 vs. T300? I just used the Titleist Iron fitter on the web, they suggested the T100 or as an alternative T100s– I currently use game improvement irons as a 9 handicap with a 90mph driver swing speed. I figured the T300 would be more my bag.

    • Matt Saternus


      It all depends what you want from your iron. The T300 will be more forgiving. If that’s your priority, there’s no reason you can’t play that.


  8. Can confirm, these are the real deal. Lived all over the lower grooves my first time out, and the ball still launches high, straight, and distances are not far off.

    Look incredible down by the ball, feel incredible.

    Very impressive.

  9. Matt- torn between the Callaway Apex pro, ZX7, and T100s. Love the feel of soft forged of them all, and the compact T100s is the best looking of the three but a little intimidating. What do you think of the forgiveness of the three?

    • Matt Saternus


      They’re all in the same range. I’d recommend a fitting to see which performs best for your swing.


  10. Hey Matt,
    Loved the article. I am a 7 handicap and previously play the P770 irons. Didn’t have issues hitting those just curious is that forgiveness rating close in the T100S and P770 or are they completely different?
