I like the story. And the test. But I spend a certain amount of time in mine and it doesn't take long for them to whiff so I clean (gently).

Thanks again for your replies. I've never really given much thought to the make-up of helmets and the various elements that may or may not degrade. My own view is that if I'm going to wear one then I might as well be sure it will work so the old ones are going in the bin unless i can find a way to recycle. That said, I ride with a number of people who don't wear helmets and it doesn't bother me. They're adults and can make their own choices.
