ABSTRACT:
A wood-type golf club head exhibiting improved aerodynamic performance enabling the golfer to generate greater club head speed during a swing includes a conventionally shaped wood-type club head. The grooves at the club head form openings which lead into passages which are in air flow relationship to vents located at the back of the club head. During a swing, air is allowed to flow through the club head by entering the grooves and flowing through one or more passages out of the vents at the back of the club head.
