What we say...

One of four golf irons in the revamped T-Series range for 2021, the Titleist T100S iron is a forged model aimed at better golfers seeking more distance.

Two degrees stronger lofted than the T100, the T100S is Titleist's "faster tour iron". Almost identical in styling (you'd struggle to tell them apart at address), the forged S is designed to look and feel like a tour iron while giving you extra yards.

TESTED: Titleist T100S iron

Titleist T100S 2021 irons.

As with the other models in the T-Series, the T100S has been built around three key Ds – Distance, Dispersion and Descent Angle. 

Created to the same dimensions as the T100, the T100S uses more dense D18 tungsten weights and the same 2000º brazing process used in aerospace construction which helps 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.

Titleist say the new variable bounce design is their "best-feeling ever" with less bounce on the heel and more on the toe for improved turf interaction and feel.

The T100S only differs from the T100 in loft and with the addition of a new muscle channel, which helps increase ball speed.

Weight savings from the Muscle Channel are shifted to produce even lower CG and better launch.

We love the new brushed chrome finish, which ensures glare will never be a problem.

The T100S is joined in the T-Series by the T100, T200 and T300.

The T100 is Titleist's fully forged dual cavity players' iron and the most played on tour. 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 T100S iron review: The tech

T100S is everything the world’s best players love about T100, only more. It provides fully forged feel, tour shaping, more versatile sole design and precise flighting – with two-degree stronger lofts and a new Muscle Channel – produce better ball speed and launch while preserving precise touch and control.

T100 but faster: The new T100S dimensions exactly match the Tour-informed specs of T100. They are designed – not bent – two-degrees stronger with a fully forged face, backed by an innovative Muscle Channel that adds to both speed and launch. At impact, they feel amazingly similar to T100. The only difference is added distance.

Better tungsten for better performance: Utilising more dense D18 tungsten weights and a 2000º brazing process applied from aerospace construction, T100S irons feature the same precise CG calibration as T100. Weight savings from the Muscle Channel are shifted to produce even lower CG and better launch. You get outstanding MOI from a solid, fully forged design.

Refined for greater consistency: Like T100, the new T100S face features a continuous cradle construction that creates a seamless striking surface and a more uniform leading edge.

What Titleist say about the Titleist T100S iron

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.

“The uniqueness of the T100S comes from the fact that we engineered the two-degrees stronger loft into the iron rather than just bend them. The reason for this is to keep the integrity of the sole and optimise its performance through the turf. That would be lost by simply bending a T100.

In addition, the ‘S’ represents ‘speed’ and the new Muscle Channel delivers it through the long and mid irons by providing longer distance, tighter dispersion and higher angle of descent for greater consistency and scoring opportunities. It has the same look and feel of the T100 but longer flight for those who want it.”

Titleist T-Series irons for 2021.

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.”
