2027 CRBN1 Fastpitch Softball Bat: -11, 10, 9, & 8

The 2027 Mizuno CRBN1 (-10) Fastpitch Softball Bat is engineered for hitters who demand explosive performance, a responsive feel, and the confidence to attack every pitch. Featuring an advanced one-piece construction, Mizuno's innovative XZone Technology, and an optimized double-wall barrel design, the CRBN1 delivers a powerful combination of pop, forgiveness, and consistency. Built for competitive fastpitch players who want a connected swing feel, this bat brings Mizuno's performance-driven engineering to every trip to the plate.

At the heart of the CRBN1 is XZone Technology, which adjusts composite angles across 10 specific zones throughout the barrel to create an expanded sweet spot. This specialized construction helps deliver more consistent performance across the hitting surface, giving players additional forgiveness when contact isn't perfectly centered. The double-wall barrel is engineered to provide high-level performance right out of the wrapper, while Cylinder Seaming supports consistent barrel response and durability. An Optimized End Cap complements the barrel design by enhancing the sound at contact and contributing to the bat's responsive hitting area.

Mizuno's enhanced Anti-Shock Construction is integrated into the taper to reduce vibration and improve durability, helping hitters experience a smoother, more comfortable feel through contact. The one-piece design provides direct feedback and a connected hitting experience, while the Speed-Helix Grip adds comfort and durability where players need it most. With -11,-10,-9, and -8 length-to-weight ratio, a 2 1/4” barrel diameter, and certifications for multiple major fastpitch associations, the 2027 Mizuno CRBN1 is ready for players who want to step into the box with confidence. When it matters, you only need ONE.
