I had tweed and hodden grey copies of my military TOS made, which are my normal kilted headress. For more formal occasions I'll wear a plain blue black Glen Garry. I'd like to get a shallower one as I find the current style of deep hats disagreeable.

If its sunny and I nned protection then I'll wear a Tilly and if its raining a leather hat. I was given a kangaroo leather one years ago and its still going strong.
