You do that to protect from the heat. The less "sun" that hits your skin, the lower your body temp. Infact, if you get a muslin cloth, you can wrap it around your head and the breeze will go through it, and if you sweat at all, it acts almost like a mini swamp cooler, to cool you off.Can't say I've ever had to do that.... Wow...
It's on my bucket list.![]()
