I wear a full face to keep warm in the winter, say below 40 degrees, or I know the whole trip will be in hard rain. In the summer I wear the smallist, non-DOT beannie I can find, as the Georgia helmet law just says I have to wear a helmet, it does not say it has to be a DOT helmet. Whenever I go to a state without a helmet law, I don't wear one at all. But each to their own. As Safety Office for the Georgia Southern Cruisers Riding Club, and an occational riding instructor, I recommend all new riders wear a DOT helmet no matter what the law is in there state, but in the heat of the South in the summer, the smaller and lighter the better. Once a person has been riding for about 20,000 miles, I figure they can make up there own mind.
