How to identify this generation
- Like the 2021 T100, but the upper badge reads 100S with a red S.
- Titleist reuses T-Series model names across generations, so check the generation marking and photo as well as the lofts.
What to notice in the specifications
- Titleist publishes one T-Series table per generation: each model has its own lofts, while lie and length are listed per club number for the whole 2021 lineup. Read the model and generation markings before matching a chart.
- Titleist labels the gap wedge “W” (with W2 and W3 for weaker models); the labels are kept as published.
- Titleist publishes the same lofts, lies and lengths for T150 (2023). The heads differ, so read the model markings rather than relying on these numbers.
Checking a club you own? These are the maker's published figures for an original build, not measurements of your club, and a source date is not the year it was made. Bending, reshafting or a hosel adjustment changes loft, lie and length, so identify the head by its own markings and have a fitter measure it when its history is unclear.
Read our loft guide for a worked example of comparing the numbers, and our used iron checklist before relying on a seller's description.
