Bern helmets offer one with a Carbon fiber shell .. they are $175, I think.

Do offer a winter kit , ear muffs etc..


Though I do think it's a capitalist solution to leaving the infrastructure dangerous,
Motor car centric , privatized transportation..
and just selling a commodity to make you feel better ,
so you don't demand a safe city.. overthrow the whole system
and rebuild it as a safer.. walk/ bike friendly City .. and nation.
