Patented No Taper Technology: Creates an even grip pressure for a more consistent stroke that keeps the putter head path on track. Traction Control: Advanced surface texture provides a non-slip grip in all weather conditions. The Specialized Cross-Traction pattern on the tacky polyurethane outer layer offers a comfortable feel. Oversized Profile: Lightweight EVA foam allows for a lighter weight grip which is critical for maintaining balance of the putter. This ensures consistency in squaring the face at time of impact.
