The Nike 20XI golf ball offers a resin core which is a more responsive core material that is lighter, and faster than rubber. This ball offers two times more RZN for ultimate tour performance with a larger, softer RZN core, and a faster RZN mantle. The 20XI goes the maximum distance for high spin tendency players. This is a tour level/ distance ball that offers the longest distance, improved feel and reduced spin for greater accuracy off the tee and a shorter approach.
