The Adams Pro hybrid features Adams' patented upside down design that increases moment of inertia (MOI) and lowers the center of gravity (CG). The low CG promotes a higher launch to help you get the ball in the air easier. To increase ball speeds the Pro hybrid has a Velocity Slot in the crown and Cut-Thru Slot in the sole. The slots allow the face to flex at impact to create a greater "trampoline effect" with the ultra-thin face.
