Hey there,

Not sure if the American Cancer Society makes sunscreen but i'll put my .02 in.

I usually use the Australian Cancer society sunscreen because it's the main product out there that's well..approved by them...of course. It's spf 30+ and water resistant for 2hrs. (For long rides i don't carry the large tube but have managed to wrangle a few small tubes from the chemist...for freeeeee..)

All i can say is put sunscreen on!!!
