I have a new C3 Pro that I made the mistake of buying a bit to small. Thanks to some fine members here informing me that the lids from XL to XXXL are all the same, just different liners, makes getting my helmet to fit right a lot easier. The problem now is I do not see anywhere that sells the liner to the C3 Pro, only the C3. I am waiting to hear back from Schuberth on this. Is the C3 the same liner? Or is the helmet just to new to have liners for sale?
