I've been getting Banana Boat, just because I know it's gluten free (for dd). It seems to work pretty well for us, but we haven['t tried it in the water. Last week we found ourselves on the way to the park without sunscree, and I got a CVS brand sunscreen that says it stays on through water for 80 minutes or something like that. The formula was similar to the Banana Boat that we usually use.

I recently went to Florida. It was the first time my pale, pale body had seen the sun for a long time. I wore both Banana Boat (SPF 30) and Panama Jack (SPF 30). Didn't burn a lick.

My favorite is UV Natural, a brand made entirely of naturally-derived ingredients. Moisturizing and very water resistant.
