Exactly! It's no joke to get sun burns! Long sleeves are another option for us, but too warm in many occasions.
We drive long distances wearing helmets, so the ears are not an issue. But the nose and lips need attention! As the helmet visor covers to our chins, but has no UV filter. So, nice 50+ sunblock and ready to go.
Agreed, even up here in the north you can get severe sunburns. As a matter of fact, we have an extermely high rate of melanoma. Great job and surely good fun making up the protective sleeves. When it comes to helmet visors etc., you need not worry. It is almost impossible to make transparent plastic/perspex/lexan/plexiglass that does NOT filter away UV radiation. Even an ordinary plastic bag will do the job, as will any window pane. The only medium that lets UV go through, is quartz glass, as you will find for example in solariums. In the old days they used quartz glass in huge balconys in tuberculosis sanatoruims, belieivng that sun radiation includung UV was beneficial. Very expensive and sadly with no effect, but that was how it was. Just a fun fact.
