  • We're celebrating our 30th anniversary the only way we know how. Introducing the 2020 DeMarini Ultimate Onslaught 30th Anniversary Slowpitch bat. We went deep into the archives and pulled from our lost designs to create a graphic worthy of the occasion. Built on a Nautalai platform featuring a Continuous Fiber Barrel and a stiff ZnX Alloy handle, the only thing hotter than this bat's look is its performance.

    By increasing stiffness and durability, the ZnX alloy handle flexes less and forces the barrel to deflect more for increased overall barrel performance


    We rolled a single sheet of super strong composite to offers consistently high performance from the first hit to the last.

  • 13" End-Load Barrel

    Built with more mass in the barrel to generate maximum energy transfer on contact.
