Yeah, but I trust them a lot more than just the DOT. lol. They have 2 specifications that I know of...M for Motorcycle, and SA for Specialty Applications such as stock car racing and drags. If all else fails, try the Bell or Simpson sites...I have an open face Bell and a full face Simpson, but I'll probably have to get a new one when I start riding...the Bell is M90, and the Simpson is M95. Just couldn't get any SA's to fit when I was racing. I know better now.
