Ear flaps. Large, faux-fur-lined, and they hang far enough down to cover the whole ear — not just the top. Buckle them together under your chin and the wind has nothing to get at.
Rear neck panel. A faux-fur-lined flap that sits down on the back of your collar and closes the gap where wind gets under.
Brow band. A thick band of faux fur across the forehead. It isn't decoration — it keeps wind off your eyebrows and cuts glare off the snow.
Buckle chin strap. Adjustable, and it means the hat stays on your head. On a ladder, on a farm bike, behind a snow blower, in a gust coming across the house.
The whole thing is a quilted wind-resistant shell over dense plush fleece, with faux fur at every edge that touches skin.
