TSi1 Hybrid

The 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.

Designed 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.

The 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.

Effortless 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.

TSi 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.

The 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.
