Unangax/Aleut hunter, Ivan Suvorov wearing a gut parka with a large harpoon, Umnak Island, Aleutian Islands, Alaska in 1909. The visor is called a Chagudax, and was worn when hunting for seafood/sea residing animals on kayaks. It was in fact to block the sunlight (as well as the bright light reflecting from snow) and was decorated to refer to social status. The shape of the visor also cupped ears, supposedly helping hearing as well. More amazing photos: https://bit.ly/3y4GtWn
I haven’t looked for it but I wonder how much was functional vs show. The do-dads on the hat, in particular.
This guy brings to mind the post above.
As usual, open in new tabs to embiggen.
