About the Titleist T100S
The T100S is the strong-lofted variant of the 2019 T100, announced in January 2020 and in shops that March. It is built on the same forged 1025 carbon steel head with high-density tungsten weighting but set two degrees stronger through the whole set: a 32 degree 7-iron against the T100's 34, and a 44 degree pitching wedge against 46. Lies, lengths and offsets are identical to the T100, so the S is purely a loft play - the same tour-compact head delivering a lower, longer ball flight. A second T100S generation with brazed tungsten construction replaced it in August 2021.

What is the difference between the Titleist T100 and T100S?
The T100S is two degrees stronger on every club. Its 7-iron is 32 degrees against 34 on the T100, and its pitching wedge is 44 degrees against 46. Lie, length and offset are identical.
What replaced the original Titleist T100S?
A second-generation T100S arrived in August 2021 with the same lofts and brazed tungsten construction, and the T150 then took over the strong-lofted slot in 2023.
Finding a used set
The Titleist T100S ran from 2020 to 2021 and is no longer in production, so the used market is the only source. Search eBay, 2nd Swing, Golf Avenue and the PGA Tour Superstore trade-in listings, and check the loft and lie against the chart above before buying — sets this age have often been bent from standard.

- Compiled from retailer and press spec tables rather than a Titleist spec sheet: titleist.com serves T-Series specifications client-side and was not retrievable. Titleist does not publish per-club bounce for the T-Series, which uses a variable-bounce sole; the column is absent from every published spec table and is therefore omitted here rather than estimated
