Anything with an SPF of AT LEAST 15 is good. I like to use 30+. If you are playing in a hot or humid climate or if you tend to sweat, then you need something water proof so you don't sweat it off. There are a few products designed for sports/active people. Don't forget to apply sunscreen to your forhead and the tops of your ears! I live in an area that gets a lot of tourists and they aren't used to the sun.. they put the sunscreen on their cheeks and burn their forheads, ears, chin, etc. up. Its easy to spot the non-natives
