Classic kilt style - as seen at large this summer in Scotland

[OC Richard]

I fully understand the need for protection from the sun, but perhaps a more Scottish and traditional option would be a deerstalker, or a fore and aft, or even a Panama would be a more appropriate option...

As long as it has a brim all around. Scottish tweed options would be things along these lines:





(Because your ears are as susceptible to sunburn as your face or the back of your neck.)

Here it's not just the sun, but sometimes the heat. That's why hats were developed with mesh around the brim, which allows air to circulate and even breezes to blow through. Ditto with straw hats if the straw has an open weave that allows air through.

Interesting that a Panama would be considered "a more Scottish and traditional option" with Highland Dress.
