Thick & Protective
Size: 6 Ounce (Pack of 2), Style: SPF 50 Spray
I like this spray because it goes on thick and stays on for a while (even when playing in water). It does spray on white and requires a quick rub in, but I know my kids are protected from the sun when using this product.

Problem with the sprayer
Size: 6 Ounce (Pack of 1), Style: SPF 50 Spray
Great scent, feels soft after it's put on, but the spray is defective. I don't know if it's just this bottle or the lot, or a manufacturing issue overall, but the spray comes out fine initially and then doesn't, getting clogged temporarily till you stop using it for a while. Then it works fine again. Otherwise I would not have a problem buying it again, if I know it's just a one-off situation with this particular bottle.

Rated #1 for use by adults and children
Size: 6 Ounce (Pack of 2), Style: SPF 50 Spray
Coppertone Waterbabies SPF 50 has been verified as SPF 50 by an independent testing agency and has been rated number one by the large Consumer product Report organization. Surprisingly many top name products do not provide the sun protection that they advertise. The spray comes out thick, it is essentially the lotion version that is sprayed from a can, but with the rub of the hands becomes transparent and wipes on easily. All sun protection products are supposed to be sprayed on the hands and then applied, even those that spray clear. I've worn waterbabies every day for the past month and I typically spend 2 hours a day in direct sun, sometimes longer. It is sweat resistant without being uncomfortable to wear. I say resistant because when working outside in humid weather I can become quite sweaty and will wipe my brow. The majority of the lotion remains on my skin instead of being transferred to my sleeve. Comfort and retained application are very important to me. Several reviewers complain about the "baby" smell. It doesn't smell so much like babies as it does regular old suntan lotion. Personally I don't really care so much about how it smells as long as it doesn't smell bad like some other expensive sun protection products do. What matters is that it works like it says it will. Like many other products it doesn't taste very good. This is probably a good thing as it keeps people and babies from eating the stuff.
