New Mizuno F24 CRBN2 Fastpitch Softball Bat Composite Charcoal/Black

dual frequency damper: mizuno's patent-pending construction combines two different materials for vibration reduction and less flex for higher performance. cylinder seaming: allows for consistent performance and durability across the barrel. stiff carbon handle: reduces energy loss when impacting the ball at higher ball speeds to put more energy where it belongs (the ball) and less where it doesn't (the handle and your hands).
