BLOCK PARTY USSSA SLOWPITCH BAT – 13” 2PC BALANCED

BUILT TO SMASH. Inspired by the iconic world of colorful building bricks, this bat delivers power you can assemble swing after swing and is made for players who love to create their own chaos.

Two-Piece Composite Construction: Advanced assembly that blends feel, flex, and pop in one dangerous package.

Balanced: Speed, precision, barrel control – our lightest barrel for your best swing every time.

DisRupt Duo Barrel Technology: Hot, forgiving, controlled performance with optimized comfort from a 2-piece design.

Technical Features:

• • Multi-Layered Barrel Engineering – Hybrid composite layup blends impact toughened composite structure for controlled flex and rebound.
• • Optimized Handle-to-Barrel Energy Transfer – Connection system precisely tuned to allow barrel flex while isolating vibration.
• • Dynamically Tuned Flex Profile – Barrel flexes slightly deeper than Mono for more whip effect, especially beneficial for players with varying swing speeds.
• • Resin-Infused Toughening Layer – Improves resistance to fatigue, ensuring consistent barrel performance over extended use.
• • Engineered Sweet Spot Expansion – Variable wall thickness paired with layered fiber orientations produces a broad, forgiving performance zone.

Player Benefits:

• • Explosive Barrel Response with Controlled Feel – Layering design maximizes pop while the connection system reduces hand sting.
• • Faster Break-In, Long-Term Durability – Game-ready composite structure delivers hot performance quickly while maintaining resilience throughout the season.

• • Forgiveness on Mishits – Barrel’s cross-ply reinforcement and dampened handle reduce negative vibration, keeping swing confidence high.
• • Balanced Swing Dynamics – Optimized flex distribution provides both power hitters and contact hitters with a barrel that responds to their style.
• • Durability Without Sacrifice – Reinforced layering absorbs stress over thousands of impacts, extending life without deadening performance. • Grip weight and manufacturing tolerance may cause slight deviation from the listed weight.
• • 2 1/4" barrel diameter
• • 13” Barrel Length

Modulated Stiffness Technology (MST): MST is our 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.
