Obviously they all have to meet the same safety standards is there really anymore to them than colour, design and price.
I used to have an Arai cant remember the model, was a Slight replica

was very comfy and kept alot of the wind noise out too.
Am thinking about sticking with the same make, just cos its tried and tested by me and i know nothing about the others that are available.
anyone know whats good and whats not so good
