Distance Performance class, 3-piece surlyn golf ball that delivers sidespin reducing performance, with explosive distance off the tee with a solid feel. Bridgestone’s proprietary new Active Acceleration Mantle layer is a key component of the 3-piece construction. The Active Acceleration Mantle is comprised of a new High-Performance Polymer material that provides increased thrust and higher initial velocity at impact while allowing Bridgestone to enhance the core for greater forgiveness and enhanced feel — designed specifically for players with greater than 105 MPH driver swing speeds.
