The helmets I grew up with we’re mainly some kind of plastic over styrofoam but in the last few years helmet that look like big hats have started to come into the market. My classmates explained in class that it hasn’t really caught on here in the US because people don’t want to look like they are cycling with a large hat. Though, when I studied in Copenhagen, those helmets were quite popular. This Bern helmet looks like something in between. The visor is attached with Velcro.
