After 4 months of ownership I have bought a helmet for fast roads and motorways. I set out to buy a Davida Jet for the quality and leather, but needing glasses for driving concluded that goggles were too much trouble. I was shown a Shoei J-O which has a built-in visor, it fits me better than the Davida and is lighter. The visor disappears up into the helmet and is super clear, replacements are about £38. Shoei J-O - Matt Brown Multi-composite contemporary yet classic look.
Caberg produce the similar Riviera & Uptown. Both have a flip up visor on the outside of the shell & a flip down smoke visor inside the shell. I have the Riviera which is almost mist free in rain just lift it a bit when stopped.
