DeMarini Whisper Fastpitch Softball Bat Review

DeMarini Whisper Fastpitch Softball Bat Review

Shhhh. Speak softly. Hit loudly!

DeMarini has made a name for itself in the fastpitch softball bat world, and the Whisper is a perfect example of why. This softball bat is built for high performance and maximum power without sacrificing comfort. When considering a new fastpitch bat, it's important to consider factors such as the material it's made of, the weight and balance of the bat, and any certifications it carries. It's also a good idea to read bat reviews and try out the bat for yourself, if possible, to get a sense of how it feels and performs. That’s where the Bat Assurance Program comes in handy! You can try any bat risk-free for 30 days. If you’re unsatisfied, send it back, no questions asked, for a full refund. If you keep it, we’ll credit the price you paid for assurance to use on your next purchase at JustBats.

DeMarini Whisper Review

Now, let’s get into the review of DeMarini’s Whisper fastpitch softball bats. Designed to deliver big hits in big moments, this model is constructed from Continuous Fiber composite material. The latest technology included in the design is DeMarini's Amplified Gapped Wall, which offers a larger gap between the inner and outer barrel that creates unbelievable pop ad a brighter sound on contact. The Whisper is also designed to provide players with extreme durability.

Other notable features include:

  • DeMarini's Paradox handle was implemented to optimize the handle-barrel connection for improved feel and power.
  • A two-piece construction to give players maximum control and power with every swing.
  • DeMarini's Pro-Cup End Cap to disperse vibrations and reduce the sting.
  • A balanced swing weight, making it ideal for both power and contact hitters. 
  • An Extended Barrel Design that allows hitters the opportunity to make better contact and generate more power.
  • Full 12-Month Manufacturer's Warranty when purchased at JustBats.

Is the DeMarini Whisper Balanced or End Loaded?

The DeMarini Whisper fastpitch bats are balanced and available in a -9 or -10 length-to-weight ratio. One of the other frequently asked questions our Bat Experts get is, what is the difference between the -9 and -10 models? Besides the cosmetics, there are virtually no differences between these two softball bats.

Differences Between the DeMarini Whisper and CF Fastpitch Bats

Outside of cosmetics, there are a few key differences between these two elite softball bats. First and foremost, the Whisper features the Amplified Gapped Wall Technology mentioned above. Two other main differences are in the end cap and the connection point:

  1. The Whisper features the Anomaly End Cap, while the CF series comes with the Tremor End Cap. Both are insanely durable, but the Anamoly is lightweight and improves barrel performance. 
  2. The Whisper features the Anomaly connection compared to the Type V Connection on the CF. Both help prevent vibration, but the Anomaly on the Whisper bats offers seamless energy transfer on contact.
