Leave it to the French to come up with helmets that look this good, I mean, these really appear to be extremely nice. If you're riding a sportbike, they won't replace a good full face helmet but they certainly will do the job if you're on a vintage ride or maybe a scooter. Jérôme Coste, (who managed to bang his head 6 times before getting interested in helmets!) is the man behind these carbon fiber beauties with claret colored lambskin liners, chrome edge trim and a level of finish you won't often see. The paint schemes vary from retro designs to classic solids but they all manage to look pretty exotic. It seems he offers silk scarves, too, which would complete the look as you ride your vintage cafe racer.
The price seems to be somewhere north of 500 Euros, that's $750+ ... interesting. More photos and links below:
