For me I started with a Multitec, was good and I still have it; kind of heavy and had to switch visors depending on lighting

The second was a Shuberth Concept; Loved the sunshade well built but was heavy and had poor ventilation.

Third was another Shuberth, a C2; Better lighter and larger sunshade, still suffered from poor ventilation.

Presently I am riding with a Shuberth C3; In short the best helmet I have ever owned, Extremely light, No fog EVER!, Quiet is an understatement (as long as you are in clean wind, turbulence seems to be a noise making issue). Good chin locking latches (worth taking one apart just to see how its made quite impressive) A bit pricy OK way to much $$$ but does come with a nice guarantee from Shuberth

I do enjoy having the option of walking into a bank wearing my helmet (just as long as the face is open) Try that with a full face
