Thunder Heat ASA Fastpitch Softball

The Dudley 4A-531 WT11Y ASA Thunder Heat 47/ 375 Softball is not nearly as susceptible to compression changes under increased temperature (100° F) and decreased temperature (40° F) compared to .40, .44 and .47 poly care softballs. This translates into a much more uniform and consistent compression ball from Spring play thru late Summer. •CORE: 47 •Comp: 375 •Size: 11 inch •Stamp: ASA •Leather Cover
