I purchased this hat when I visited my sister at Martin Luther College in 2003. I was a grad student at Illinois and I went up to visit her and her boyfriend (now husband) for a weekend. This hat saw a lot of wear and tear as golf and workout hat. According to some people, MLC had to change this logo because they were given a decease and desist from Gary Player. His logo is very similar. There is no label, but it feels like polyester.
