Multiple southern states and a few midwestern states are at "extreme threat" levels of "wet bulb temperature".

You could do that. Or you could wear light clothes :)

Well, clothes made with the right pigments might work in a similar way. But regular light clothes aren't enough in a wet bulb event. Regular light clothes can keep you from getting further overheated due to sunlight, but if the ambient air temperature and humidity is such that you can't get evaporative cooling from your sweat, you're still in trouble. Sky-cooling pigments can cool you below the ambient air temperature by up to 4°C even in direct sunlight, which could be life-saving in certain circumstances.
