Holds up
Size: 3 Fl Oz (Pack of 2), Style: SPF 30, Size: 3 Fl Oz (Pack of 2), Style: SPF 30
Reliable, long-lasting protection. I’ve used this for workouts, beach days, and long hours outside, and it holds up really well. It absorbs quickly, and actually stays on when you sweat. Great value for the size and performance. Definitely a go-to sunscreen for active days. I like the small size. It is easily portable.

TSA approved but…
Size: 3 Fl Oz (Pack of 2), Style: SPF 30
I’m not super picky when it comes to sunscreen and I needed a sunscreen that would be TSA approved. This fit the bill and didn’t break the bank (getting a 2 pack is nice as well). However, I find that this sunscreen just underperformed for me. It could be that I should up the SPF factor but when using my usual brand their 30 works a bit better than Banana Boat’s version. I wouldn’t say that this product is useless because it did prevent burning in certain areas but I still burned a bit in other areas. However, this could be my fault. I was outside for about an hour with 9 UV rays in a bikini in the California sun. I will say that I did reapply before 2 hrs so I’m just a little bit let down that it didn’t quite perform a bit better. But again, could be user error and perhaps just be really particular about your application technique.
If you’re in a pinch, go for it but I’d honestly even recommend upping your SPF factor if you are set on Banana Boat’s while still meeting the TSA sizing requirement. Smells good though and isn’t the stickiest compared to some of the other brands!

Good sunblock. New bottle design with easy to read expiration date.
Size: 8 Fl Oz (Pack of 1), Style: SPF 30
When reviewing this product. It ask you to put a STAR for:
Sun protection
Water resistance
I put 5 stars because, how would i know? I don't use it to go into water and you'd need to be a scientist testing how good the sun protection is. I just assume it works.
But i've used banana boat sunblock in the past. And it's been fine. No sunburns. As long as you remember to re-apply it because it's not meant to last all day.
Pros:
- It's sunblock
- It works (from my previous experience)
- New bottle design.
They changed the style of the bottle. The new bottle has the date on it. The old bottles only had a serial number. In order to find out if your old bottles are expired you had to go to the banana boat website and see the instructions on how to read the serial # that way you can know the expiration date.
The new bottle is more simple, the date is laid out easy to read on the bottle.
- Long expiration date:
I bought this sunblock around april or may of 2020 and the bottle says it will expire January 01, 2022
- Nice slim bottle to fit into a small bag.
Cons:
- It's a small 8 FL OZ bottle. My old bottle is a 10 FL OZ. Not sure if they still sell the 10FL OZ.
- It feels a little heavy and thick on the skin. But after a while it's fine.
- If you rub your hands / fingers around your eye, especially if you're sweaty. You might get the sunblock into your eyes. That has happened to me on hot summer days. It will make you teary eyed and irritate your eyes for a long while.
- I hear this sunblock may stain clothes. So far that has not happened to me.
