I usually use my wooly bobble hat.
BUT!!!
I have what I call my "Darth Vader" hat that i bought for winter golf. Black Sympatec fleece lined peaked hat with pull down sides that go all the way round the back makint is a bit like dart's helmet but without the facemask!. My wife thinks I need a face mask for disguyise when wearing it though!
If i can rustle up a photo...
