Its not a brimmed hat, but I wear a rabbit fur bomber hat when its really cold. Prefer it to most things, but I don't have nearly the hat selection that some of you must have.
Bomber hats are warm to be sure, probably the warmest choice of all. However, I wear glasses and highly prefer a hat with a brim to keep glare and snow off of them. Also, 10 years ago I had cataract surgery and bright sun hurts my eyes much more than it used to. A cap of some kind is a must.
Someone said that the Kromer hats aren't as good as they used to be. I posted that I wear one and added a photo of my red plaid Kromer Rancher. It's not the best fitting hat I've worn and the ear flaps aren't as warm as they could be, but it does work. It has a tendency to ride up in back so I often have to push it back down. A shaped ear flap that came down over the ears but not so far down over the neck would probably reduce the riding up.
