The Nike 20XI golf ball features a combination of advanced technology resulting in the RZN core. The RZN core delivers more distance and performance around the greens. The enhanced material allows for faster initial velocity for more controlled shots and higher levels of MOI. Recycled golf balls have not had the original characteristic of the ball altered in any way. Recycled is a cleaning process only. The golf balls are soaked in a non-abrasive cleaning solution and then go through a washer specifically designed for golf balls.
