Just to be an ass, I'll throw in that there are things like Guarder C4s which have an elastic strap, foam for sealing the goggles up against your face, etc. They have high coolness factor, and by the accounts of people who've used 'em the polycarb lens is as good as any other out there.
But as far as I can tell they aren't rated for anything (ANSI, ASTM, ESRB, nothing) :P
