Great product
Size: 3 Fl Oz (Pack of 1)
Really like this item for kids. Easy to apply with minimal white residue left. Do have to apply more frequently.

Great product
I bought this SPF because it was on the EWG site. We used this for a southern carribbean cruise. I am very pleased! No sunburn but got a great tan. Easy to apply. Highly recommend!

Works well even in water.
Was able to apply and use for hours even in water without reapplying. Usually burn but not with this. It does go on white and very thick but runs in.

Good, not perfect
I do like that this is safer for the environment. And it goes on just fine. Not greasy or anything. If you only use a little and rub well, your skin doesn't turn a ghostly white. Does great and I never have to reapply even after being outside sweating in heat and humidity all day. BUT, for some reason this is the only sunscreen I've ever used that has left a black ring around my finger where my wedding band sits. I've used a ton of sunscreens and I'm not sure why this one does it, but it's super annoying.
