Deliver monstrous hits in big moments and silence the opposition with one swing. The 2023 DeMarini Whisper (-9) Fastpitch Bat boasts an original Amplified Gapped Wall Continuous Fiber Barrel, one of the most advanced technologies to ever come out of DeMarini’s Oregon factory. Extra space between inner and outer walls empowers the Whisper’s continuous fiber composite barrel to jumpstart the ball on contact, resulting in potent exit velocities and extra base hits. Whisper employs a two-piece composite construction to maximize your power output, and its Anomaly Connection System with a stiff, trumpet-shaped handle dampens vibration while still responding to mis-hits. Ideal for advanced hitters looking to launch the ball over the wall, the Whisper (-9) fastpitch bat delivers a balanced feel, brighter sound and dominant performance.
