First Look: Titleist Shows Off Newest 2025 T-Series Irons

Well, well, well, the time has come, and this week on the PGA Tour and the DP World Tour, Titleist is launching their newest T-Series irons for all the world to see. This is what is known as the "Tour Seeding" part of the process that Titleist employs when launching new products, which allows the public a sneak peek at what the folks have been cooking up at Titleist R&D.

“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.”

So with this being our first look, let's dive into what Titleist has been up to and see if we can gain any knowledge based on these first pictures.

What Titleist Has To Say

Beyond talking player performance in a very unspecific way, Titleist isn't ready to give us any deatils on whats going on inside of the newest T-Series irons, but thanks to the supplied images we can make a few observations and predictions.

T100 and T150

From first look, its heard to tell what if anything is new from a pure looks perspective with the T100 or the T150, but when you're some of the most played irons on the PGA Tour it's understandable to now sway too far from what's working.

One thing that is hard to tell from the supplied images (but is a bit easier to see with the USGA conforming list picture below) is that the sole design looks to offer more trailing edge relief.

More bounce and more relief seems to be the continued trend for irons across the board from a number of manufacturers and dynamic sole designs that transition more through the set helps with versatility.

On the subject of iron testing Titleist ambasador Russell Henley had this to say “[With] 9-iron, what I want to do is hit one really hard and be able to put it way up in the air. 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. Then when I get into my [long] irons, 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... Golf is getting to be more and more specific and the more technology, the more that we're learning about the game, the more every shot needs to be approached a little bit differently and be attacked in a different way.”

The talk about more control of launch and spin variability through the set makes me believe a bit part of whats going on will be how the tungsten (a staple in the T-Series irons) will be progressively positioned in the set.

T250 and T350

The biggest departures from the current line looks to be the T250 and T350, which have moved to a solid body construction rather than relying on a composite badge. The badge tended to be a point of contention for a lot of players for any number of reasons beyond performance, but it looks like Titleist has altered their manufacturing process for these to offer a solid body construction.

Based on pervious models, it's unlikely there will be any sort of polymer material used to fill the entire cavity, but until we have more information, thats pure speculation on my part.

T-Series Utilities

(U505 and T250 Utilities)

To round out the line up Titleist is also introducing (just in time for the U.S. Open and soon to follow Open Championship) are the T250 and U505 utilities. I'm willing to bet that these two new options will draw their tech from the new T250 and T350 irons, but in a package specifically designed to offer better utility performance.

No Word On New Forged CB or MB Irons

Two clubs missing from this new iron announcement are a forged CB and MB models, but in my opinion, this is a non-story (yes, I'm writing a story about a non-story).

Here's why.

I think we've certainly come to a time in golf club design and technology history, that we can say with reasonable certainty that forged blades and cavity backs (void of any multimaterial advancements) aren't getting better. Yes, they can be customized, and certain models will work better for certain individual players, but overall, beyond a tweak in sole design, center of gravity, or just looks, it doesn't make much sense to rotate blade models every two years.

Now we get to play the waiting game to see who will be the first players to put these new T-Series irons into play, and wait until Titleist has more info to offer about what technology is going on inside these new irons.
