Nice refreshing sunscreen
Great spray sunscreen. Don't even notice any difference between this organic sunscreen and regular sunscreen. It sprays nice and evenly and provides good protection for a reasonable time. I've used this during a number of workouts out in the sun, sweating, for a few hours at a time. It sprays pretty lightly on, and stays on. Once it sprays on, while it feels light, you do feel it (like a little sticky on your skin), same as any other sunscreen really though.

Great summer scent, easy to apply, non greasy.
We LOVE spray on sunscreen. So much easier to apply, especially to yourself in the harder to reach areas. My kids like it better too, doesn't take as long so they can get to the fun stuff. This smells great, I love summer scents. It doesn't leave you feeling greasy or like you've just tarred and feathered yourself in cream and then sand. It's an SPF 50, so extra strong and does well at protecting. I do wish it was a little cheaper, so I watch for it go on sale and stock up.

Best sunscreen ever!!!
This is the BEST SUNCREEN. It’s all we use-and I know, I know it’s expensive (standard is $30 a bottle) BUT it does go on sale quite often for like $20 ish which is what competitors run for and this is WAY cleaner. It’s made of a lot of organic ingredients and this one smells summery but they have unscented options too-that’s normally what I get! You can get spf 30 or 50 and they both work so well, never been burned wearing it. It’s a fine spray that goes on clear and dries quick-no white cast, no rubbing in. We live in a hot state that is sunny a lot of the year so we need a good sunscreen year round and this ticks all my boxes. This is the best product coola offers!! My entire family uses it.

THIS IS THE BEST ****MINERAL**** SUNSCREEN THAT EXISTS!!!!
Style: SPF 50, Size: 5 Ounce (Pack of 1)
I don't review products that often but after reading countless numbers of reviews complaining about this product I had to say something. I have bought bottle after bottle of this sunscreen and it is by far my favorite. Oh my gosh yes, YOU HAVE TO STILL RUB IT IN. So, so many comments complaining they are burnt or theres no even coverage. This is mineral sunscreen!! You have to rub it in still! You will not get burned if you literally just follow the instructions. "It's greasy" Again, it's Zinc Oxide. Yes, it is going to be greasy but I'll tell you what, I've purchased SO MANY different mineral sunscreens and this one is by far the least greasy and ACTUALLY RUBS IN COMPLETELY. After a few minutes, your natural skin color is back, no more white. I have not used a single other mineral sunscreen that I can say that about. I really hope they do not stop making this product because I love it so so much!!! Please, do not expect something out of this product that is physically impossible. But its seriously the next best thing.

Great Sunscreen for Kids
Style: SPF 50, Size: 5 Ounce (Pack of 1)
I used this Coppertone Pure and Simple Kids Sunscreen Spray on my kids during a recent beach trip, and I was really impressed. The spray application is super convenient, especially when dealing with active children who won’t stay still. I love that it’s made with zinc oxide and is completely tear-free—no complaints even when it got close to their eyes. It’s mineral-based and gentle on my children’s sensitive skin, with no irritation at all. The SPF 50 provided great protection, and I noticed they didn’t get sunburned even after hours of playing outside. It’s water-resistant, so I didn’t have to reapply constantly after swimming. I also appreciate that it’s free from harsh chemicals and fragrances. The 5 oz size is perfect to throw in a beach bag or backpack. It’s definitely become my go-to sunscreen for outdoor playdates and sports. I highly recommend it to any parent looking for a reliable, kid-friendly sunscreen.
