Can we add a face guard or C-flap to my child's batting helmet?

Only with the helmet maker's approval. Batting helmets must meet NOCSAE standards and carry the NOCSAE stamp, and altering a helmet can void that certification.

• Add-ons bought separately (such as a C-flap): the helmet manufacturer must provide a notice saying the attachment doesn't void the helmet's NOCSAE certification, and you must show that notice to the umpire before the game. Without it, the helmet can't be used.
• Helmets sold with a cheek guard already fitted by the manufacturer or an authorized dealer don't need a letter.
• Don't repaint or tape a helmet. Stickers and decals are allowed if they aren't excessive.
