Have tried and used many helmets before (Atmos, Propero II, Octal, Blade etc.) but my first impression is that the Synthe trumps them all. The fit is very comfortable, helmet feels and looks high quality and my size M weight only 216g. I ordered also the Cinder (MIPS), and while fit seems identical, the weight difference is noticeable as the Cinder MIPS weighs in at 299g. Admittedly, I haven't ridden the Synthe yet, but I think this one's going to serve me well for a long time. Wish I had bought one a long time ago and not wasted my money on other helmets.
