A grip for the handle of a golf club having at least a polymerized region with two or more polymers. The first and second polymers cooperate to form a pattern on the top surface of the region. The region may be combined with a substrate to form a sheet. The sheet may be formed into a grip interface having any of a number of shapes including a panel shape. In the case of a panel shaped grip interface, the panel is then attached to an underlisting sleeve to form the grip. The grip reduces impact shock and provides a feeling of tackiness in the manner of a spirally wrapped polyurethane-felt grip while allowing the use of multiple colors being polymerized together. The grip may be easily installed onto a golf club shaft and further accommodates the use of polymers including various different characteristics including level of tackiness or durometer.
