Variable Face Thickness

Variable Face Thickness (VFT) is a golf club design technology that optimizes ball speed and forgiveness by incorporating different thickness levels across the clubface. This innovation enhances distance and accuracy, even on off-center strikes, making it a key feature in drivers, fairway woods, and irons.

VFT works by distributing thickness strategically—thinner sections generate faster ball speed, while thicker areas improve stability. Golf manufacturers use VFT to create clubs that maintain consistent performance, allowing players to achieve better energy transfer and reduced distance loss on mis-hits.
