Hello Soren
I am interested in this too. Schuberth makes the C2 which is a flip face and the S1 which is not. The S1 is way expensive at around $750 for the one I looked at. It is a really quiet helmet from what I could tell. The C2 seems to be pretty back ordered and is still in the $450 range. Somewhere I read a review on the web that wasn't real high on the C2 and that kind of turned me off. There must be others that have this feature.
