## Overview

The DeMarini FP Whisper (-10) is a 34-inch, 24-ounce two-piece composite fastpitch softball bat engineered for advanced high school and college players. Featuring a balanced swing weight, Amplified Gapped Wall Continuous Fiber Barrel, and vibration-dampening trumpet handle, it maximizes power, bat speed, and comfort. Designed to deliver louder hits and superior energy transfer, this bat is a top-tier choice for elite hitters seeking consistent extra-base performance.

## Description

Elite hitters looking to launch extra-base hits with the perfect blend of responsiveness and power can take full advantage of the 2023 Whisper (-10) Fastpitch Bat. With a balanced swing weight optimized for power and extraordinary exit velocities, the Whisper (-10) uses a first-of-its-kind Amplified Gapped Wall Continuous Fiber Barrel, among the most advanced technologies to ever come out of DeMarini’s Oregon factory. Extra space between inner and outer barrel walls jumpstarts the ball on contact, and continuous fiber composite materials empower advanced high school and college players to deliver big hits across the outfield grass. Whisper employs a two-piece composite construction for responsiveness on contact, and its Anomaly Connection System and trumpet-shaped handle offer a stiffer feel than Prism+ and CF while dampening vibration. The balanced feel, brighter sound and dominant performance make Whisper (-10) ideal for advanced hitters in high school and college fastpitch softball.
