Bottle leaks
Size: 6 Fl Oz (Pack of 1)
great product, the only complaint is the bottle leaks. It seems to be all brands of liquid spray repellents. I double bag in ziplocks but it is still a mess. The company that can figure that out will have us travellers eternally grateful!

Reliable protection that stays put during workouts!
Style: SPF 50, Size: 8 Fl Oz (Pack of 1)
I’ve tried many expensive name-brand sunscreens, but this Amazon Basics version performs just as well, if not better. It’s become my go-to for morning runs and trips to the beach because it actually stays on even when I’m sweating.
Why I gave it 5 stars:
Non-Greasy Formula: Unlike other sport sunscreens, this one absorbs quickly and doesn't leave that heavy, sticky film on my skin.
Actually Water Resistant: I’ve used it for laps in the pool and long hikes; as long as I reapply as directed, I haven't had a single sunburn.
No "Sting": One of the best things is that it doesn't run into my eyes and sting when I start to sweat—a huge plus for runners.
Great Value: You get a generous 8-ounce bottle for a fraction of the price of "premium" brands. The fact that it’s formulated without Oxybenzone is an added bonus for peace of mind.
If you’re looking for effective, no-frills sun protection for an active lifestyle, you can't beat this. It’s a staple in my gym bag now!
