Featuring an ultra-lightweight build, including a lightweight shaft and grip, the GT1 Driver is engineered to promote faster club head speed and improved launch conditions for the moderate swing speed player. Titleist's relentless pursuit of speed, known as the Titleist Speed Project, reaches new heights in the GT family, a byproduct of the new Thermoform Crown. Crafted from a new proprietary matrix polymer, a substance never used before in the golf industry, this revolutionary material unlocks unprecedented design possibilities while maintaining Titleist's signature sound and feel. Specifically, the crown creates discretionary weight that, in the GT1, is strategically repositioned to generate the deepest center of gravity in the GT driver lineup. As a result, the GT1 delivers an exceptionally high launch and optimized speed, spin, and stability. The next piece of Titleist's speed formula lies in the incredibly fast face. An upgraded titanium Speed Ring stabilizes the perimeter of the face, allowing the center to produce the maximum ball speed permitted under USGA regulations, while variable face thickness ensures minimal dropoff on mishits. Finally, the GT1's new construction and weight distribution enable a more aerodynamic shape. With its shallower face depth, this design reduces drag, moving swiftly through the air to elevate club head speed.
