6 1/8 - 6 1/4 hat size
19 1/4 - 19 3/4 inches
Although this is a youth's helmet, I bought it for myself and am an adult. I have only put it on my head three times and it has never been near a motorcyle since purchase - the dream was there but I've never bothered buying or riding a motorcycle.
Meets or exceeds DOT standards. CAD technology used in fit and finish. Three vents that can be open/closed. "The CS-Y is quite simply one of the best fitting, true youth sized full face helmets with features and comfort normally found only on full size adult helmets."
I am firm on the $50 as I know the value of this helmet and it truly has never been worn. Comes with soft helmet bag and owner's manual.
