Great kid stuff
Size: 6 Ounce (Pack of 1), Style: Spray
This stuff is great and works well for kids and adults alike. Used at the zoo this past week and on my young kid almost every day. Yes, really, but does really well. I have not had any burns or irritation with this product. Spray, rub and go. Easy to carry and a lot of product in each can.

Works great feels great
Size: 6 Ounce (Pack of 1), Style: Spray
Definitely worth the money I still bought 2 of these bottles, but I found it locally cheaper in stores so I would check them out first but I do still highly recommend because of how good it works!

Best sunscreen for kids
This is the only sunscreen my son can use. He has very sensitive skin, and can’t use a lot of other sunscreens. This covers great and is a little thicker so you know it’s staying on.

Like it but doesn’t rub in great
Happy with this sunscreen even though it’s hard to rub in. Keeps us protected from the sun and lasts us quite awhile!
