Approximately 300 MLB® players chose to wear the Rawlings S100 Pro Comp this season before the league-wide rule goes into effect in 2013. The mandatory use of the updated version of Rawlings S100 batting helmet is outlined in the new, 5-year collective bargaining agreement signed last November by Major League Baseball and Major League Baseball Players Association™. This protective provision was specifically included in "Health and Safety" category (Section VIII) of the labor agreement.

Constructed of aerospace-grade carbon fiber, the new Rawlings S100 Pro Comp batting helmet continues to provide technologically-enhanced protection for ball strikes up to 100 miles per hour.
