Nike first launched their RZN core inside the 20XI S and 20XI X balls that launched in 2011. Now, the latest edition to the RZN family is the Nike RZN ONE ball. With a slightly different formulation to the 20XI tour ball, the ONE RZN is designed for increased distance.

The reformulated RZN core is a highly neutralised polymer that is light and faster than conventional rubber cores. The design sees an increase in core size and improved performance.

Slightly firmer than it's RZN counterpart, the RZN ONE X ball, the RZN ONE delivers longer, more penetrating shots for the player who has a faster clubhead speed, or steeper angle of attack on their shots.

“With ONE RZN, we are able to bring revolutionary advances in golf balls to a wider range of athletes,” said Nike Golf’s Product Development Director for golf balls, Rock Ishii,. “There’s not a product out there in this category of golf ball that has technology of this magnitude.”
