Question for men going thin on top

[Haze]

so, i have reached the grand old age of 35, and am now getting to the point where i can feel the sun burning the top of my head after about 10 mins, but to be fair i have friends that were going bold at 20, so i think i am doing well.
Now the question is, what do you wear on your head? do not really want to go down the base ball cap root, but not sure what else, what do you guys wear when out and about

cheers

i still have a bit of hair on top, i can just feel it getting through
