While military helmets may need to stop a bullet, Major League Baseball is requiring helmets that will be able to withstand a baseball strike of up to 100 miles per hour. This season approximately300 MLB players will wear the Rawlings Sporting Goods Company S100 Pro Comp batting helmet this season before the league-wide rule goes into effect next year.
The helmet, which is constructed of aerospace-grade carbon fiber, is 300 percent stiffer and 130 times stronger than traditional plastic helmets. The use of the helmet is part of a mandatory rule outlined by a new five-year collective bargaining agreement signed last November by MLB and the Major League Baseball Players Association.
