Remember kids... always wear a helmet. (The almighty bikeradar helmet thread)

Well you could get the hardhat version. ...In my opinion though in summer you are not gonna be comfortable in something which isnt well vented.I've tried riding in a skate lid and it sucks. I dunno, it just seems a bit daft - I would either get a proper helmet or not bother. I think that those Bern ones make you look more silly than if you just got a proper bike helmet.

Yup, if you're going to wear a helmet, just get a proper one and stop being embarrassed of it. Cheap helmets always look bad and are false economy anyway, either don't wear one at all or just get a more expensive from giro or something.
