High flex handle
The Dynamic Performance Optimized Barrel (DPOB) is Marucci's next-generation barrel design built to give you better power, pop, and feel. Using advanced layering techniques, the DPOB barrel flexes just right -- no matter how fast you swing or where you make contact. It
delivers top performance across the whole sweet spot, so you get more out of every swing.
Modulated Stiffness Technology (MST) is Marucci's unique system that connects the barrel and handle in a way that fine-tunes how the bat flexes. By adjusting the materials in key areas, MST creates the perfect balance between flex and stiffness -- giving you better energy transfer, control, and feel. The result is a bat that dynamically adapts to the player’s swing, delivering optimized performance at every point of contact.
USSSA, NSA, and ISA certified
1-year manufacturer's warranty

 |  | USSSA Certified Softball Bat
 USSSA has used a 1.20 BPF standard in its softball programs for 15 years. The BPF standard was developed by NYU Physics Professor Dr. Richard A. Brandt over 15 years ago. The BPF standard is based on fundamental laws of physics that allow Dr. Brandt's testing lab to measure the relative performance of bats to be used in USSSA play.
