Re: Is this a real 49ers early 80's GU helmet?Opinions please
The red or green dot is done at the Bike helmet factory (and later Schutt) to specify the size of the air bladder. Red is a medium bladder for a medium helmet, while green is a large bladder for a large helmet. Black or dark gray is for an XL. Every Pro AiR, AiR Power, or Pro AiR II has the color code.
