I was standing in 14F weather on opening day a few years ago, watching frost flowers growing in the morning light, and thinking about why I hadn't bought one yet. Stormy Kromers were quite popular a long time ago and still are, from about Iowa north. Winter being what it is up there, I can see them as almost mandatory.
They are based on the forage cap issued to troops during WWI, with a large ear flap which folds down around your neck and then fastens under your chin. Very necessary in the trenches in France, and they were reproduced by commercial makers for outdoorsmen. America still had a large agricultural base and we did a lot of stuff outdoors in town in the winter, too. Walking to school a mile uphill both ways, etc.Splitting wood for heat. feeding the chickens, delivering newspapers at O'dark thirty in the morning before school. Children and adults kept busy.
The "no hat" Presidency of Kennedy changed that, and we began to notice a division between the urbanized sheltered look seen in movies and magazines, vs the hard working country folk who weren't about to go out all day with nothing on their head. You used what you knew worked, and the Kromer worked. It worked for servicemen in France, too. The military design changed, but the European variety were very similar - the German army issued one - and that further distanced us from wanting it. Too much baggage.
Another change in design came and that was when other makers just added ear flaps only, which tied under the chin, leaving the back of the neck exposed. Works ok if you have a tall collar on your winter coat, but those aren't as prevalent now, either. So, the Kromer has a better advantage. Real Kromers have a full drop down cape which wraps the neck - "mad bombers" have just ear flaps, and a lot of those are seen in parodies of rural life or caricatures promoted by the city perspective. They never wear them, almost don't need to - unless you are postal delivery, etc. Standard fare for working men and women.
I haven't bought one yet, and it goes to temps in my neck of the woods - 14F was rare. Typically it's 44F daytime temps winters here, and beanies, hoods, and gaiters do well. We wore a lot of gaiters this last year and now I have a bit of a collection, Kryptex snow, Edge, etc. all put away for hunting and they are NOT coming out any sooner. Not even.
I'd sooner wear a Kromer than mask up again.
