Hammer is proud to offer the broadest range of core and cover options in bowling. We are excited to enhance the product line by adding a “big” shiny symmetric ball, the Hazmat. The Hazmat is a lower RG and higher Differential core that will help the ball pick up in the mid-lane and have a strong and continuous down-lane motion. The base cover is the extremely popular and highest-performing HK22, and we’ve used the Symtex Hybrid additives. The core and cover combination of the Hazmat creates a big hooking and never-quitting ball motion that bowlers love to see.
