Reef safe sunscreen
Style: Sensitive Skin, Size: 6 Ounce (Pack of 2)
I bought this for Hawaii as a reef safe option. I have sensitive skin so I have to be careful about what sunscreens I buy - this worked great and did not irritate my skin. It's a bit thick but it's an SPF 50 so that's not a surprise. A bottle lasted an entire week in Hawaii. A great product for sensitive skin!

Really good!
Size: 0.5 Ounce (Pack of 1)
My daughter (11 yrs) used to hate putting any sunscreens on her face as she'd find them stikcy. But this one is working very well for her and she's now using it without any concerns for stickiness. I'd buy again.

Very good purchase
Size: 0.5 Ounce (Pack of 1)
I purchased the Banana Boat Sport Kids Sunscreen Stick SPF 50 (0.5 oz) for my child, and it has been very convenient to use.
The stick format makes application quick and mess-free, which is especially helpful when applying sunscreen on a busy child. It glides on smoothly and provides good coverage without feeling overly greasy or heavy on the skin.
I like that it is travel-sized, making it easy to carry in a bag or keep on hand for outdoor activities, school events, or vacations. The SPF 50 protection gives me peace of mind for extended time in the sun.
It also seems gentle on the skin, and my child tolerates it well without irritation. The compact size makes it great for reapplying throughout the day as needed.
Overall, this is a very practical and effective sunscreen option for kids. I would definitely recommend it for parents looking for an easy, portable, and reliable sun protection product.

So Much Easier Than Lotion Sunscreen
Size: 0.5 Ounce (Pack of 1)
I bought this mainly because getting regular sunscreen on my kid turns into a full argument every single time. This stick version made things way easier. I can swipe it on quickly without getting sunscreen all over my hands or in my child’s eyes. We used it outside for soccer practice and park days, and I liked how it stayed on even with sweating and running around. It also fits easily in my bag, so I keep taking it with us instead of forgetting sunscreen at home. Honestly one of those products I didn’t expect to care about this much, but now I’m glad I ordered it.
