9Iron, great article. Yes, last year I drove a race wearing jeans and a long sleeve cotton shirt. Why? The organization allowed it. They don't any more. Now, I own a 3 layer suit and three single layer suits. I have nomex underwear and socks as well as Carbon X underwear and socks. I have a Nomex skirt for my helmet. I have nomex hood as well as a Carbon X hood. It scared me to death to race in what I did last year. I had the 3 layer suit, but it was 100 degrees that day and I didn't have a single layer suit. While I do have Moobs, I don't wear a bra. I'm an old fat man.
