Machka has hit upon Neutrogena sunscreens as they apparently feel less greasy that other traditional types.

I am an advocate of using clothing to avoid sun exposure. I work outdoors and wear long-sleeve shirts and pants all the time, even if temps are up around 40+ deg C.

I have taken to wearing loose-fitting trousers for cycling (and randonnees), and the majority of my jerseys are long-sleeved.

In summer, I grow a beard to assist fascial protection, and usually it comes off in winter.

I have thin to no hair on my head, and a bandana is standard wear almost anytime I go riding. Otherwise, I wear a cap.

Jess' cape is a good idea, although I would be inclined to prefer it for touring, and then probably would use a collared shirt or jersey and my bandanas with supplemental applications of sunscreen.

Maybe you should also post in the Touring Forum (if you haven't already).
