The 2025 Mizuno B25 Duality Hybrid -10 USA Youth Baseball Bat features a 2 5/8-inch barrel and hybrid construction, combining a Hot Metal™ alloy barrel with a Black Onyx composite handle for a lightweight, controlled swing profile.
The barrel is built with Mizuno’s Hot Metal™ Alloy, a high-strength aluminum designed to allow thinner barrel walls while maintaining durability. CORTECH™ Barrel Technology varies wall thickness across the hitting surface to create a wider sweet spot while helping reduce MOI for improved barrel control and swing speed.
The Black Onyx composite handle provides a lighter, stiff connection through the swing, while Mizuno’s seamless hybrid transition joins the composite handle to the alloy barrel. The -10 configuration and balanced swing feel make the Duality a manageable big-barrel option for youth hitters using USA Baseball-certified equipment.

OPTION GUIDE: Should I order this bat stock/untouched or Heat Rolled with Progressive Pressure?
If you order your new bat Heat Rolled with Progressive Pressure, it will be delivered to you completely and evenly broken in. This process adds 20-40ft of distance to your solid hits, increases consistency, improves durability and adds 2-3 business days of lead time to your order. If you plan to use the bat in an official game or event, please verify the legality of our process with your league or sanctioning body before use. We (LongballBats.com) do not encourage the use of a Heat Rolled bat in any game or event where it is against the rules. Click here for details about our process!
