Callaways longest 3-piece golf ball just got a distance upgrade with better feel. The new HX Hot continues to push the boundaries of ball speed allowed under the rules of golf. The new high-speed hot core has a higher resiliency for even longer distance while providing the enhanced feel preferred by better players. The new Speed Layer increases ball speed off the driver and the Ionomer cover with HEX Aerodynamics has been optimized for long, penetrating ball flight that provides superior performance from tee to green.
