Pricey but works
Size: 3 Fl Oz (Pack of 1), Style: SPF 100
It works well and is definitely worth it, but it's pretty small and pricey for what you get.

Works great, TSA compliant!
Size: 3 Fl Oz (Pack of 1), Style: SPF 100
I LOVE spf 100, I know people like to say anything above 30 or whatever is pointless but let me say, when I use spf 100 I don't tan at all (and I DON'T want to tan, I'm Asian and the kind of person who walks outside for 5 minutes and I'm visibly slightly darker) and my husband is white and burns if out in the sun too much but this stuff not only prevented burn but I think also prevented tan for him too 🤷🏻‍♀️ I think these bottles are also awesome to be able to fly with too, we bought a few for our Punta Cana trip and we didn't tan or burn, and we only used a little over one bottle for 5 days (we only wore when we'd be out in direct sun a few hours each day, and my outfits didn't show a LOT of skin so less surface area). I hope this company continues selling this product, it'll always be my go to for travel sun screen now :)
