I use arm sleeves instead of slathering on sun screen. It's faster than applying sun screen, and there's no clean-up afterwards. I've owned sleeves from many different manufacturers, and these have been my favorite. They're longer which allows you to pull them all the way up to your arm pits, and still have plenty to cover your wrists. The ribbed material may actually help them cool better, and they're a little thicker which likely means better protection from the sun. I'm only sorry I didn't buy a 2nd pair.
