The latest addition of the Avatar Series drivers, the new Avatar Inversion maintains the same cup-face design to ensure the maximum coefficient of restitution (COR) not only in the center of the face, but also over the entire hitting surface. Just think of it as one oversized "sweet spot". The Inversion has two very unique inverted carbon crowns not seen in tandem on any club in the market to date! This lowers the center of gravity and moves material toward the rear portion of the sole to reduce the spin rate for greater initial ball velocity at impact.
