They all wore them in the 60s and 70s where I grew up. In the winter they wore this hats with ear flaps. They walked the route then. You could tell when the Sears catalogs were coming because the used a two wheel push cart and a huge mailbag.
My father worked most of his life outdoors at a sawmill, and he always wore one of those. One of them had a hole in it where a chunk of wood was thrown back out of the saw and hit it.
