Titleist TSi2 and TSi3 push the boundaries of speed through advanced engineering and material breakthroughs like the ATI 425 Aerospace Titanium face — a material used in the construction of jet engines and NASA’s Phoenix Mars Lander.
However, working with something as tough as ATI 425 Aerospace Titanium isn’t easy, which is why no one else does it. But this unique alloy, made by a single foundry in Pittsburgh, is the key to creating a driver face that delivers increased ball speed at every point of contact, ultimately allowing for the production of the longest, straightest, best-looking and best-sounding driver we've ever made.
This innovation continues to be validated by the world’s best. Since introducing the new TSi drivers at the Safeway Open, Titleist has continued its run as the preferred driver choice at each event to begin the 2020-21 PGA Tour season — notching yet another week most recently at The CJ Cup @ Shadow Creek. But don’t just take our word for it; check out what Team Titleist has to say about new TSi2 and TSi3 drivers:
