Nike Golf is taking the lightweight RZN core technology used in the 20XI line to a new level with the introduction of the new RZN franchise. Consisting of four models - RZN Platinum, RZN Black, RZN Red, and RZN White, the new line of golf balls is built with a proprietary core technology (Speedlock RZN) that tightly connects the core to the mantle layer through a unique interlocking design. This technology prevents the core from slipping away from the mantle during impact, creating a more efficient transfer of energy through the layers of the ball and increased speed off the clubface.
“Tightly-wrapped material pulls more energy through the layers and converts that energy into additional ball speed. One additional mile-per-hour produces an average of two to three yards in additional distance.” - Rock Ishii, Senior Director, Golf Product Development, Nike Golf
