Engineered with aerospace-grade Aluminum Alloy, the Mizuno PWR Alloy offers great performance and durability, while also providing a balanced swing weight for increased swing speed. A Multiband Barrel design incorporates multiple thickness levels along the barrel to create a wider speed spot for more forgiveness and explosive power. One-piece construction generates less flex and more energy transfer to the ball to boost performance. Made with Mizuno's Cushioned bat grip for a great feel.
