Athletes know it is important to exercise and tone their core, but engineers who have studied the golf ball apparently realized that its core is important too. Nike Golf made quite an impact when it released it premium 20XI golf balls, which featured a new innovation called RZN last year.
The new proprietary RZN technology resulted in lighter, faster and a more responsive core. Nike Golf took this a step further by adding more RZN to its 20XI ball. Nike claims this larger, softer RZN core improves feel off all shots while maintaining driver distance. The added RZN mantel offers the promise to produce longer shots off irons while providing a softer short game feel, while this combination of core size and mantle could translate into two times more RZN material than the previous generation 20XI.
The new 20XI will be ready to tee off in February.
