Dudley Thunder ZN Pro-M Softball

These balls are specifically designed for USSSA-sanctioned play. While they are the official ball of the Men's Conference USSSA, you should check your local league's specific rulebook to ensure they require the 0.52 COR rating before purchasing.

The flat seam design minimizes air resistance compared to raised seams, which helps the ball maintain a more consistent and predictable trajectory. This is particularly beneficial for achieving the precise flight paths required in competitive play.

A 0.52 COR (Coefficient of Restitution) rating indicates how much energy is retained by the ball upon impact. This specific rating is engineered to balance performance and safety, providing a responsive feel off the bat while adhering to the standards set by high-level associations.

The ultra-thin ZN composite cover is built for high-level, competitive use. It is designed to withstand the rapid energy transfer that occurs during hard contact, maintaining its shape and performance integrity over the course of a game.

While the polyurethane core is resilient, composite-covered balls can behave differently in extreme cold. If you are playing in temperatures below 50 degrees Fahrenheit, you may notice a slight decrease in performance or responsiveness compared to warmer conditions in warmer conditions.
