A natural progression from the award winning Giant 420-S driver- HiPPO's XXL Beta Titanium Driver features a similar head design that incorporates a unique energy cell system designed exclusively for HiPPO golf. The energy cell system incorporates two polymer cell chambers located deep in the back of the club- positioning the center of gravity for optimum launch angle and increased playability. The energy cell system also minimizes the loss of kinetic energy on impact resulting in greater conversion of energy to the ball and distance. Manufactured from 6-4 titanium- the XXL driver has a deep face design and power channel soleplate to create excellent impact efficiency for penetrating- powerful drives. The XXL driver comes with a specially designed- custom lightweight graphite shaft in regular and firm flexes. HiPPO's premium velvet grip fitted as standard
