DeMarini Whisper -10 Fastpitch Bat 2025

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.

Anomaly Connection: Pairs the barrel with a stiff, composite handle to offer feedback while maximizing comfort, bat speed and energy transfer on contact.
Anomaly End Cap: Designed to work with composite barrels, using light and durable materials to reduce swing weights, improve bat control and optimize performance.
Amplified Gabbed Wall Continuous Fiber Barrel: Inner and outer barrel walls with a larger gap increase performance and create a brighter sound on contact.
0.800 Thrumpet Handle: Dampens vibrations while providing a solid feel.
Balanced Swing Weight: For total barrel control.
Two Piece Composite Construction: Designed for improved weight distribution that allows for great balance, bat speed and barrel control.
Gabbed Wall Continuous Fiber Composite Barrel: Long, uninterrupted threads of carbon fiber composite material shaped into a barrel create superior strength and consistency across a larger optimized hitting area or sweet spot.
2-Piece Composite Construction: Designed for improved weight distribution that allows for great balance, bat speed and barrel control.
