In 2012, Nike released a new line of golf balls called 20XI that featured a new lightweight core material called RZN (resin). According to Nike, the lightweight resin cores moved more weight to the perimeter of the ball, increasing MOI to make the balls more stable in the wind. The problem was, the golf balls spun too much on iron shots, causing control problems that negated the ball’s higher MOI.

Rock Ishii, director of product development for Nike Golf, said that the company has solved that problem with its 2013 20XI golf balls. Like last year’s models, the new balls have four layers and a urethane cover. But the new models feature a construction with a larger, lower-compression RZN cores that decreases iron spin and allows for even more weight to be moved to the outside of the ball for an even higher MOI.

According to Ishii, one of the main advantages of the 20XI ball is that its high-MOI construction causes less spin decay after it reaches its apex. This means that the 20XI will to spin more consistently than lower MOI golf balls, which will help stabilize their flight during the critical period between apex and landing.

The new 20XI golf balls are available in two models — the 20XI and 20XI X. The difference between two is that the 20XI X has a cover that is six compression points firmer than the 20XI. This will make the 20XI X spin less than the 20XI from driver to wedge, making it a better option for certain golfers with high swing speeds. The street price of both balls is around $46.

Along with the 2013 models of the 20XI, Nike has also released its One RZN golf balls, which offer a lower price point that the 20XI golf balls.

The One RZN balls feature a RZN core and have a compression of about 60 — 20 points softer than the 20XI golf balls. That makes them a good choice for golfers with slow swing speed. The One RZN balls are available in two models — One RZN  and One RZN X — and will retail for around $30.

Like most non-premium golf balls, the One RZN balls have surlyn covers that producs less spin around the greens than balls with urethane covers. Watch the video interview below with Rock Ishii and Zak Kozuchowski for more information on the One RZN balls.
