Just about everyone who puts on serious mileage here in SD wears some sort of arm cover because the sun is brutal and will burn you up without mercy. They wick moisture and actually do have a cooling effect when you're sweating like crazy.
They're also really nice in those unfortunate parts of the country that have cold weather.
