Seamless Thermoform Crown A reimagined ultra-lightweight design, born from a new Proprietary Matrix Polymer. The tunable acoustic properties of this unique composite allow Titleist engineers to realize new material gains while maintaining the signature sound and feel. All wrapped in a clean look that inspires total confidence. Split Mass Construction A breakthrough in internal weighting unlocks longer drives and enhanced directional control in GT3. The Adjustable CG Track now sits closer to the face for more dynamic CG control, while additional discretionary mass is pushed to the back of the club to maintain optimal stability through impact. Speed Ring VFT Face Two technologies come together to create GT's amazingly fast face. An upgraded titanium Speed Ring stabilizes the perimeter to produce maximum allowable speed in the center, while a variable face thickness (VFT) preserves consistently fast ball speeds across the rest of the face. Advanced Aerodynamics GT3 features a new raised tail contour that represents a dramatic shift in driver aerodynamics. Previously impossible to execute due to design constraints, this advanced shaping results in a driver that swings faster while still providing optimal CG control. Personalized Speed-Tuned Performance The Adjustable CG Track in GT3 is now positioned closer to the face. This magnifies the impact of each track weight position, giving you even more ability to maximize every MPH while encouraging your ideal shot shape. Speed/Distance
