Dudley Thunder SY NSA Slowpitch Softball (Dozen)

The Dudley Thunder SY is a 12" NSA-certified slowpitch softball with a synthetic cover — a durable, cost-effective game and practice ball for programs that want dependable performance without the price of a leather ball. The synthetic exterior shrugs off scuffing and wear, while the poly center delivers the consistent response players expect from the Thunder line.

Key features & specs:

• NSA certified — approved for sanctioned NSA slowpitch competition
• .44 COR / 400 lb compression — firm, durable spec built for consistent slowpitch play
• Poly (polyurethane) center — solid core delivers repeatable performance across the dozen
• Synthetic cover — resists scuffing and surface breakdown far better than leather under heavy use, with high-visibility optic-yellow color
• Regulation 12" size
• Sold by the dozen

Coach's tip: Synthetic-cover balls are ideal when you want game-legal performance that also survives batting-practice duty. Care: Wipe down after wet or muddy games, air-dry, and store indoors at moderate temperature to keep the cover and core in top shape.
