re: People that wear vests. What is this?

I always wear a vest in the winter instead of a coat. I get too damn hot with a jacket or coat and a vest keeps me warm around my core. I live in a town of less than 3,000 people and a lot of country people have always worn vests. I am not sure about what soy boys are wearing since I never go to cities and only see soy boys around here who are passing through.
