XXIO Premium golf balls use the ultimate in technology to help players achieve optimum performance. The specially adapted lower compression design delivers unequalled distance, enhancing the game for golfers with slower swing speeds. The 3-piece construction combines Energetic Gradient Growth core technology with a tungsten-enriched mid-layer to deliver improved spin and feel. XXIO Premium golf balls feature an incredibly high Moment of Inertia (MOI) that minimizes sidespin for a straighter ball flight.
