VFT in Woods and Irons
In woods, adjusting the face thickness with VFT Technology maximizes ball speed and perimeter weighting for more distance and forgiveness. The face is thicker in the center and ultra-thin around the edges, which allows more energy from the impact of the clubface to be transferred to the ball.

In irons, VFT Technology allows Callaway Golf engineers to lower the center of gravity for optimum trajectory with each iron in the set, giving a higher launch angle in the long irons and better trajectory height in short irons and wedges.
