In Switzerland, I could drive around the M3W without helmet. But from my motorcycling I know, little objects (stones, branches) CAN actually hit you and leave serious injuries!
For me personlly, some head protection is a must. But please no helmet. And please not one of those leather caps.
I have found the "Ribcap". Ribcaps protect - not as good as a helmet maybe, but a lot more than an ordinary cap. Thanks to sewn-in protectors. Soft, viscoelastic protectors instead of a hard shell. They reshape themselves and so absorb the impact energy. The products are mainly sold to cyclists and for any winter sport. They come in various shapes, colours and in summer as well as winter qualities.
