Looking for a new helmet and stumbled across these.anyone any experience or opinions.cheers

Is that the same Carrera as the bikes?

No, it’s Carrera the Italian helmet manufacturer, not Carrera which replaced GT, which replaced Saracen and was replaced by Boardman* as Halfords “we need a good brand we can run into the ground for a few years making them progressively cheaper and cheaper until people stop buying them” brand.

*who seem to be avoiding the same fate by not having a reputation to ruin therefore actually having to be some good.
