The Hammer Fugitive Pearl bowling ball takes the Juiced Pearl coverstock and introduces the Fugitive symmetric, low RG and high differential core. This combination give the ball a strong skid-flip reaction and is great on lanes that have broken down. This bowling ball is Carbon Fiber Infused! Carbon fiber is one of the toughest materials on earth. Hammer decided to add this material to the inner core of this ball for added strength and durability allowing them to offer an incredible 3 year warranty.
