Thanks for posting this! I've been meaning to get something in this vein.
A bit of advice for those like me who don't like sunscreen, long sleeve fishing shirts with SPF protection are awesome for hot weather. They breathe wonderfully and have kept me from burning despite all day rides. I don't like that they're all plastic of some kind, so I've been looking into hemp shirts, they naturally block uv, and I've had good luck with them as well.
