I must have over a dozen hats.
I'm going bald, and get sunburn easily, but I often forget to tke a hat on trips, so I end up buying a new one every other summer.
Very soft peak caps, sometimes with a nape of neck shade, that I can roll up and stuff in a pocket. Or the sort of hat that cricketers were (but not always white).
I have a Panama hat, that comes out now and again, and a straw "cowboy" type hat, too.
Oh, and two waxed cotton hats: a wide brimmed hat and a flat cap (it fits into my Barbour pocket more easily).
And for cold days I have a rabbit skin shapka made in China for the Russian market (but it's got to get [b}really[/b] cold, like -15°C for me to wear it).
And thats before I mention silly hats
