I've been wearing a cloth mask my wife sewed up. Between it and sunglasses, there isn't much for the sun to shine on. I'm actually liking wearing the mask, it filters out some of the road dust, white flies, and other bugs that I used to have to eat. Makes it a little more involved to take a drink, but not a show stopper.
When I wrecked last year, they cut my Pearl Izumi sun sleeves off of me. I've been using my older pair of cheapo Nike's I had bought at a big box sporting goods store. They don't work as well. I'll have to order some more before it gets in the 90's here.
