Nice looking hat Tanks. As I think you know, I have been wearing Rands for over twenty years now. Once you are measured, and had one made, it is nice to know every other one after that will be a perfect fit.
Like most people who own and wear a quality hat, I have no use for wool felt. It is a lousy material, compared to fur (and especially beaver) at repelling water. And like all wool when wet, they tend to stink. They are also very unforgiving in the heat compared to a properly fitted beaver felt hat.
That said, the experts on the appearance of "real hats" and the people who wear them should look around a Texas sale or diner. When working, virtually everyone down this way wears straw - whether working horseback or on equipment. A beaver hat tends to be for business or perhaps funerals or just because.
I virtually always hunt Africa, or the American west with a brimmed hat. I have a close and enduring relationship with my dermatologist, and that is a mutual agreement. In really hot weather, I often use a cotton crushable, particularly if it is a difficult travel destination. Though, I have used both in the Zambezi Delta of Mozambique. I have never found a brim a problem stalking game.
