Having been riding for several years, yet safety conscious, I decided to replace my helmet with a good one, a Shoei, chosen for its supposed better airflow reducing the "booming" that happens after about 50mph. It doesn't work that well, even at £240 and that wasn't the most expensive one. I still use earplugs too. However, how the hell do they manage to design a front air vent that allows insects through live? There should be some sort of mesh. I'm getting fed up of some flying thing buzzing around in my helmet after flying through the tiny vent in the front. A bee or wasp would not get through thankfully. It also has a vent on top and I have had to pull up in the past and remove my helmet because I can feel some bloody thing wriggling about in my hair between my bonce and the liner. And another thing, how the hell do the insects survive the encounter? Bees and others bounce off the visor occasionally, but other bugs go splat on it, usually leaving a string of vile green guts smeared.
