a guy at work reckons he does quite a few k's each week. He carries his helmet in the elevator and puts it in his locker, it don't smell !!
While the smell from my helmet threatens Climate Change...
funny thing is, he has long curly hair and looks kind of like a Pink Floyd guitarist so you reckon he'd have more odour than me,

seeing as I have a Marine Sgt-Major hairstyle !!!!
I give up, and just hang my lid from my top tube, in the Company-supplied Underground Neutral Transport-device Storage facility. Other riders don't appreciate it though.
