Question about Shoei Cns-1

Yes, the example picture is a bit confusing. But the reflection depends on the incidence of light. This has the advantage that you can still see well in cloudy conditions and quite well in the dark.
But this also means that it is not a strong reflection - if that is what you are looking for. But in sunny weather you shouldn't be able to see into it. I don't have the helmet with me at the moment.
