Ok,, stupid question here????

What is the purpose of wearing a "Dew rag" with your helmet? :? I see them on guys in winter, summer, spring, and fall. What are they for? I am talking about the bandanna looking things that tie around your head.

Do they keep you from getting helmet hair, sweating, or what,,, just wondering? :?:

I guess this post shows my "Newbieness" doesn't it,, but if I don't ask then I won't know. :wink:
