Those ones are just stickers on another brand's product. Not sure why Oakley doesn't officially produce stuff like racing shields or biking time trial shields. I mean, they do it for football and hockey already.
I have been saying this for ages. Oakley should come up with their own helmets. That would be cool. They have done a full race suit, race shoes, and other tech wear. A helmet, would complete the package. Of course, helmets have become a specialised piece of technical equipment. In F1, Schuberth has become the choice of helmet for the top drivers in the field. It would be a whole new world for Oakley to delve into given the safety standards that are required to keep up. But its not just F1. Helmets for any occassion, whether its for road, off road, or race, or even components for a helmet, eg. shields or visors, could be something looked into. The O symbol on the shield of Kimi Raikkonen (as well as Fernando Alonso, of which Oakley is also a personal sponsor) shows the partnership of Oakley being the official supplier of eyewear to the Ferrari F1 team, and the line of Oakley/Ferrari collaboration of sunglasses to the public. On the helmet right above, of Marc Marquez, Oakley is a personal sponsor in this case, not with Honda. They endorse quite a few MotoGP riders up and down the pit lane regardless of motorcycle make. Ducati used to have that special collaboration with Oakley for the best part of ten years, which has been taken over with Ferrari recently.
There was actually a pic posted in the community section of oakley.com years ago where one driver had a visor with Fire iridium on it. Looked crazy awesome with that much iridium. I'm just assuming it's an Oakley custom of course, but it could just as easily been another brand's visor.
