I went out and bought an old fly away helmet a few years back when the city of Boston made us wear them to deliver. The thing was like wearing a broiler on my head. After I quit that job I gave up on the helmet. With the start of this winter I began to wear it again and will now have to go out and buy something a bit more ventalated so as not to cause some kind of heat stroke come summer time. But then again I could just put that money towards a new frame.
