DeMarini Onyx

DeMarini's Half & Half technology separates the handle and the barrel, allowing them to flex independently. This design helps dampen vibration on off-center hits while creating a whip-like effect through the hitting zone.

The doublewall construction creates a trampoline effect upon impact, which generally allows for more barrel flex and increased ball exit speeds compared to single-wall designs of that era.

The rotation index is a visual guide printed on the barrel that helps you track how much you have rotated the bat between swings. By rotating the bat slightly each time, you ensure even wear across the entire surface, which helps extend the life of the composite material.

This bat features a 1.20 BPF certification, which was standard in 2007. Because league regulations change frequently and vary by organization, you should check your specific league's current bat list to confirm if this model is still permitted for sanctioned play.

As a vintage model, the Onyx offers a stiffer, more traditional composite feel than many modern bats, which are often engineered for a lighter swing weight and larger sweet spots. It is best suited for players who prefer the specific feedback and performance characteristics of mid-2000s equipment.
