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.
