Softball’s most electric players can power their lineups with the 2025 Whisper (-10), a Rose Gold fastpitch softball bat engineered with an Amplified Gapped Wall Barrel for the ideal combination of responsiveness and power. Designed with space between inner and outer barrel walls to trampoline the ball on contact, the 2025 Whisper (-10) Fastpitch Softball Bat helps elite players convert swing speeds to serious exit velocities. DeMarini engineers constructed Whisper’s barrel with Continuous Fiber Composite materials, a process that results in extremely consistent performance to rack up base hits. Whisper’s two-piece composite construction, complete with an Anomaly Connection System and trumpet-shaped handle, offer a stiffer feel than other DeMarini bats while dampening vibration, empowering advanced high school and college players to swing big.
