Combat is the first to feature our new Alpha Premier coverstock, an evolution of HK22C that delivers a clean motion through the front with a defined move downlane. Wrapped around the brand-new Rampart core, this shiny asymmetric brings a higher RG and lower differential than any recent Brunswick Pro-Performance release, resulting in a shape thats intentionally more controlled, yet still explosive. We didnt aim to build the strongest ball in the line; we engineered Combat to be the most versatile shiny asymmetric in your arsenal, with the ideal blend of skid, flip, and consistency that translates to better scores.
