From a Today Show story, Rawlings — the leading maker of batting helmets — is raising standards across the board:
Now the company is designing a set of helmets with the age of the batter in mind. There’s a helmet for younger players that is lighter and designed to withstand a 70 mph hit. For 12-16 year olds, helmets are a bit heavier, but can withstand the force of an 80 mph strike. Helmets for high school and college age kids can take a 90 mph impact, while those rated for major league baseball players can withstand a 100 mph hit.
You can’t prevent all injuries, obviously, but it’s good to see this kind of thing.
