Reliable Spray for Hard-to-Reach Spots and Reapplication
Size: 5.5 Ounce (Pack of 1)
I picked up this spray specifically to cover the spots I can’t reach with lotion (my back), and it’s been super handy. The spray applies evenly, and while it has a familiar sunscreen scent, it fades quickly. I’ve worked it into my routine for touch-ups, especially on homeward-bound afternoon bike commutes. I keep the can in my bike bag and give everything a quick respray before heading home. It holds up well during activity and gives me solid protection for about two hours, after which I reapply. One thing to note: it does leave a bit of a shiny finish, which is fine for arms and legs, but I skip it on my face during the day because I don’t love the reflective look. That said, if it’s late or I’m not worried about how shiny my face is, it does the job. The SPF 100 is a plus for extended sun exposure, and I like knowing that I’ve got extra coverage when I need it.

Protected my kids through 7 hours of sun and water—no burns at all!
Size: 5.5 Ounce (Pack of 1)
This sunscreen is the real deal. We spent a full day, about 6 to 7 hours, at a water park under the blazing sun. My kids were running around nonstop, in and out of the water, and we reapplied every 30-45 minutes. Not a single sunburn. Their skin looked exactly the same by the end of the day, no redness, no irritation. Meanwhile, I skipped sunscreen and got absolutely fried. Lesson learned. Goes on smoothly, doesn’t leave a sticky residue, and held up amazingly even with water play. I’ll be buying this on repeat all summer.

Smells great. Tough to remove.
Size: 5.5 Ounce (Pack of 1)
The smell is great and very nostalgic, but it has a sticky/tacky feel on the skin. It's hard to get off even with a lot of scrubbing with soap and hot water. They weren't joking that it stays on through water and sweat.

A TERRIFIC FIND FOR US IN ECUADOR
Size: 5.5 Ounce (Pack of 1)
Here in Ecuador, this product isn't even available to us. I have the most precious 20 month old girl living with us and of course I wanted to get a quality product at less cost. This fits the bill. With an SPF 100 rating from a decades old and trusted manufacturer and a price that is less than one third of what I would have to pay for any sort of water resistant equivalent, this was a no brainer. If you buy this product, please read the instructions and follow them. It is a spray product that great care should be used to avoid spraying directly on the face--------- either your own or the child's. Spray it on your hand and apply it to any face that needs it. It's convenient for neck, shoulders, backs and legs due to its spray delivery. Our little 20 month old must be part fish because she loves the thermal pools we take her to and this product seems quite durable
