I have no problem wearing my custom beaver felt hats in bad weather (including my Penman). Trust me they can take it. I also wear my rabbit felt, Campdraft and Garrison Raiders hats, they don't care a bit.
I'm much more careful with my vintage hats though, I have no idea what a soaking will do to them, but I suspect I won't be happy!
Did stop raining this afternoon though - I ventured out in my grey Whippet from the early 50's.
