Wilson Duo Soft golf balls have completely new design for the distance player. The newly-formulated two-piece design provides lower spin off the driver, exceptional distance performance and unmatched soft feel. Duo Soft golf balls have an industry-low compression rating of 29 for the softest feel in a premium 2-piece golf ball. A 3 percent larger core increases velocity to maximize your distance. Wilson reduced the depth of the dimples by 5.7 percent for higher launch and longer distance.
