Watch
Rated highest for feel and looks; its softest dimension is workability.
You're a 10-36 HCP at 70-90mph (senior, junior, or low-swing-speed player) who wants the most forgiving 2021 Titleist hybrid + ultra-lightweight build + high launch + premium Titleist build quality.
Your swing speed exceeds 90mph (the TSi2 or TSi3 will produce more distance), you want a workable head, or you want current-generation Titleist MOI gains (use TSR1 or GT1).
Pros
- Titleist's highest-MOI hybrid at 2021 release — most forgiving Titleist hybrid ever made at that time
- Effortless and incredibly smooth — sole glides over turf + soft, muted feel off face
- 20g lighter than standard hybrid + ultra-lightweight Aldila Ascent shaft (40g/50g/55g flex options)
- Golf Digest Gold Hot List recognition + 16-position SureFit hosel + 4-loft ladder (20°/23°/26°/29°)
Cons
- Niche fit — designed for moderate swing speeds (<90mph); higher-swing players will not benefit
- Now 4 years old — superseded by TSR1 (2023, +15% MOI) and GT1 (2025, +5% MOI vs TSR1) — three generations of MOI gains since
- Below-average distance vs mainstream hybrid field — engineered for slow-swing target, not raw competition
- Limited workability — large wood-style profile + extremely low CG resist shape control
By dimension
Forgiveness
StrongThe TSi1 has a bigger sole, the highest MOI, and is the most forgiving of any hybrid Titleist has ever made. The TSi1 is about greater MOI and launch, and is the highest MOI hybrid Titleist has ever built. TSi1's deep CG locations have been optimised to generate the launch and spin needed by moderate speed players to carry the ball farther, while maximising off-center ball speed through high MOI properties. Great consistency in strike and flight. Above-average forgiveness — Titleist's most forgiving and highest-MOI hybrid at release + larger wood-style profile + deep CG for off-center stability.
Distance
SolidDesigned for moderate swing speed players (less than 90 mph) to carry the ball farther. TSi1 hybrids are engineered to deliver high launch and mid-spin. Launches the ball with ease, with great consistency in strike and flight. No hybrid that launches higher than the TSi1 as a stock package. Below-average distance for the broader market — engineered for sub-90mph players to GAIN distance via lightweight/launch, not to compete in raw distance vs mainstream hybrids.
Workability
FairThe TSi1 is a lightweight design for moderate swing speed players — built for ease-of-launch, not shape control. TSi1 hybrids are engineered to deliver high launch and mid-spin. Wood shape rather than an iron shaped hybrid. Larger profile head with extremely low CG. Below-average workability — explicitly designed as the high-launch lightweight GI variant for slow swings; wood-style large profile + deep+low CG resist shape control.
Feel
StrongEffortless and incredibly smooth, the sole seems to glide over the turf and the club launches the ball with ease — great consistency in strike and flight, as well as soft, muted feel off the face. TSi hybrids designed to make them feel and sound better while offering increased forgiveness and control. Above-average feel — effortless, incredibly smooth impact + soft, muted feel off the 455 Carpenter Steel face + consistent strike feedback.
Sound
StrongTSi hybrids designed to make them feel and sound better. Soft, muted feel off the face — sound paired with feel character. Limited specific sound data — most reviewers focused on the TSi2/TSi3 acoustic profiles, and TSi1 sound feedback is light beyond 'muted' character. Mid-tier sound — muted character paired with the soft feel, engineered acoustic profile from Titleist; lacks specific reviewer detail to push higher.
Looks at address
StrongThe TSi1 is more of a wood shape rather than an iron shaped hybrid. It is shiny black in colour, with light silver accents on the sole. Larger profile, wood-type design. Effortless and incredibly smooth visual impression at address. Above-average address — confidence-inspiring large wood-style profile + shiny black crown with silver sole accents + premium Titleist aesthetic.
