it's funny how words can take on very diff meanings in diff cultures using the same language.
re this sun thingee, I have tried on sun arm blocker sleeves, and the pair that I got with a set of bike clothes once are much hotter than other brands that I have tried on in stores, so hopefully this specific one recommended here will work well. As the fellow stated, it is still going to be better than getting a sunburn on your head, and being careful of that is pretty darn important nowadays.
