** AT THIS TIME WE ARE NOT OFFERING THIS BAT SHAVED **   

Built to smash. The Block Party USSSA Slowpitch Bat – 12.75” 1PC Loaded (MSPBP1LU) brings colorful chaos with serious pop, combining a traditional one-piece feel with a slightly end-loaded (Loaded) swing weight that’s balanced enough for all to swing—and dangerous enough to do damage. Designed for players who want clean, connected feedback and game-ready performance, Block Party delivers power you can assemble swing after swing.

At the core is DisRupt Mono Barrel Technology, engineered for hot, forgiving, controlled performance with optimized comfort from a one-piece build. A Unified Composite Matrix creates a continuous carbon/resin layup to eliminate weak points between the handle and barrel, while Layered Fiber Architecture and an Optimized Flex Gradient tune stiffness and responsiveness so the sweet spot stays lively and the trampoline effect stays strong. The Pre-Conditioned Composite Resin is built to yield slightly early for a faster break-in, while a Durability Shield Layer helps resist microcracking and delamination to keep the pop lasting longer. Add Modulated Stiffness Technology (MST) to fine-tune flex and stiffness through key zones, and you get a bat that feels locked-in, responsive, and ready to punish contact.
