The new Top-Flite D2 line of golf balls have been reformulated so they play even longer with the same soft feel. The critically acclaimed Dimple in Dimple Aerodynamic pattern, named one of Time Magazine’s Inventions of the Year in 2007, reduce drag and improve lift to give these golf balls a potent combination of distance and control for a wide range of swing speeds. The Top-Flite D2 Distance Golf Balls feature a high speed core and ionomer cover designed to provide longer shots from anywhere on the course.
