This hat was made by Top of the World and is 100% polyester. I wore this hat a lot 3-6 years ago. It is very comfortable and unique. Pretty sure I picked it up at Academy. Very interesting day. I recorded voice overs for Festival International at KRVS in the morning. I also signed a lease for a new space to house my business in the afternoon. To top it all off, Louisiana beat LSU in baseball in the evening.
