Whisper (-10) Fastpitch Bat: Drive the ball for extra bases and silence the opposition with one swing. The 2023 DeMarini Whisper (-10) Fastpitch Bat boasts an original Amplified Gapped Wall Continuous Fiber Barrel, one of the most advanced technologies to ever come out of DeMarinis Oregon factory. Extra space between inner and outer walls empowers the Whispers 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 and trumpet-shaped handle offer a stiff feel while dampening vibration. Ideal for advanced hitters looking to launch extra-base hits, the Whisper (-10) fastpitch bat delivers a balanced feel, brighter sound and dominant performance.
