The modern cowboy hat is at least as much a stylistic and cultural symbol as it is a practical piece of headgear. Do you know what the most common hat in the “Old West” period of the US was? The bowler. Even cowboys, railroad worker, and gunslingers wore them. Very little sun protection there, but it was sturdy, and it would stay on in the wind.
Source for this? Up until when are you referring? It’s well known that JB Stetson’s “Boss of the plains” hat was far and away the most widely worn hat in the “old west” period, specifically BECAUSE it had a wide brim for shade and was sturdy and hardy to stand up to the elements and hard use.
Originally the boss of the plains was sold with a flat brim and open crown. This means the top of the hat was rounded, not creased like they are sold new now. The crease in the top of the hat in the old days was a product of how you picked the hat up, how you held it, how it was pinched in your fingers over time when you took it off or put it on. Similarly did the curve in the brim happen. If you took the hat on and off by grabbing the brim, the brim would bend and roll in your hand, and eventually the roll would stay put there while you wore it too.
I join the OP in puzzling over why the cowboy hats of the last 70 years or so have the brim so severely curved up on the sides. I think it is purely a fashion thing, and has been so long enough that now even “real” working cowboys don’t know the difference. Plus the fact that you probably can’t even buy a flat-crowned regular felt hat these days. If a cowboy wants real shade rather than costume fashion he is better off buying a rattan gardening hat from Home Depot or something.
