Named the official championship softball of the NCAA and NAIA, Rawlings ASA Fastpitch Softballs deliver exceptional performance on game day. Unlike competitors' two-piece balls, Rawlings 11-inch yellow leather softballs are constructed using innovative Superdot three-piece technology. The inner layer consists of a Poly-X Core for consistent spin and durability, followed by a C-LOK adhesive barrier that repels moisture and helps maintain compression, and a pro-leather cover that delivers just the right amount of tack. These softballs are designed with 375-pound compression, a COR of .47, and raised red stitches to provide a better grip.
