Titleist has become the first golf brand to use ATI 425 Aerospace Titanium, a material that was originally developed for ballistic armour and used in NASA’s Phoenix Mars Lander..

Using ATI 425 in the TSi2 and TSi3 drivers has allowed Titleist’s engineers to create the brand’s fastest ever face that produces a fast ball launch from any point of contact.

New Face. New Possibilities.

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, USA, is the key to creating a driver face that delivers increased ball speed at every point of contact.

Faster In The Air. Faster At Impact.

Improved aerodynamics lead to added speed that you can turn loose on the course with confidence. TSi is tuned to feel fast in your hands and look square at address, with a shape as satisfying as the sound.

Multi-Dimensional Stability

Players often equate “high MOI” with heel to toe forgiveness, but Titleist employs a more holistic approach to MOI design. Their inertia also delivers more speed and a tighter spin range up and down the face, freeing you to attack every drive.

Performance-Tuned Adjustability

TSi3 Drivers feature a new SureFit CG track technology, offering five unique positions to adjust club head CG to fine-tune ball flight with neutral, heel or toe settings. Titleist continues to refine how a fitter can fine-tune performance to ensure you get the most out of every swing.
