GT1 represents Titleist’s biggest technological leap in drivers, featuring an ultra-lightweight construction with the deepest CG in the lineup. Designed for effortless speed, high-launching mid-spin carry, and maximum forgiveness, it suits moderate swing speeds but is fully adjustable for any player seeking higher launch and optimized spin.

Features & Benefits

Seamless Thermoform Crown: A revolutionary ultra-light Proprietary Matrix Polymer optimizes sound and feel while maintaining strength. The clean, confidence-inspiring design enhances performance with material gains and tunable acoustic properties.
Split Mass Construction: A breakthrough internal weighting system separates mass within the clubhead, strategically positioning weight rearward for higher launch and forward for optimized speed, spin, and forgiveness.
Lowest, Deepest CG: Featuring the deepest CG of any GT Driver, GT1 promotes higher launch and increased stability, helping you achieve longer, more effortless drives with greater control.
Speed Ring VFT Face: A reinforced titanium Speed Ring stabilizes the perimeter for maximum speed at the center, while a variable face thickness (VFT) design preserves consistently high ball speeds across the face.
Stability & Weighting Control: An interchangeable back weight allows precise headweight and swingweight adjustments during fitting, optimizing launch, ball speed, and stability for your ideal GT1 performance.
