Hammer is calling it what it is... a legend. The Black Widow Legend takes the proven history of the Black Widow line and turns it up a notch. This is the first ball in this line to use a hybrid coverstock. This ball is aggressive with it's polished cover and then combine it with popular Gas Mask core to provide awesome movement on the backend that carries through the pins. 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.
