2023 Mizuno CRBN1 F23 Fastpitch Review

You might be surprised that the 2023 Mizuno CRBN1 was the most common bat in the 2023 NCAA Fastpitch College World Series. Mizuno sponsors many schools and, instead of choosing their two-piece CRBN2 or the CRBN1 PWR bat, the elite players end up choosing the single-piece 2023 CRBN1. To make it even crazier, the CRBN1 from 2021 was a top 9 bat for the CWS too. In other words, the CRBN1 is an excellent bat that the best in the game choose to swing day in and day out. It’s a real sleeper.

2023 CRBN1 Models

Models Overview

The CRBN1 is a single-piece composite bat with a big barrel and a light swing. Like the Easton Ghost, it uses a double-barrel wall design. The CRBN1 single-piece design gives it some stiffness–although its complete composite design does allow for some flex and an excellent feel on hits and mishits alike. Overall, we think the bat is highly underrated and at a price point most can be excited about.

General Recommendations

The bat has a drop 13, 10, 9, and 8 so has the correct swing weight for any hitter. If you like a stiffer feel and want to buy a bat that is a bit off the beaten path, realizing the stiffness will be more than what you might be accustomed to if you’re coming from a bat like the Prism or LXT, then we highly recommend the 2023 CRB1.

Reviews By Model

Comparable Bats

There are virtually no other single piece composite bats on the market that are getting the publicity the 2023 Mizuno F23 CRBN1 get. Other companies focus on two piece composite bats and multiple barrels. The Mizuno CRBN1 really stands alone as a great bat at a great price point.

Previous Bats

The previous bat version, the 2021 CRBN1, is also a single-piece composite bat with a big barrel and a lighter swing. There were some tech changes to the barrel, but we didn’t find them enough to feel like the bat was considerably different. Both swing light, have a big barrel, and, for a single-piece bat, good flex to help dampen stings on mishits.
