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.

Easy to use
Size: 0.5 Ounce (Pack of 1)
This Banana Boat Sport Kids Sunscreen Stick is super easy to apply, especially for little hands. Provides good sun protection and the travel size is convenient. Would be perfect if it were a bit smoother on the skin, but overall very practical.

Such a great product that my child can apply it themselves and no more eyes burning
Size: 0.5 Ounce (Pack of 1)
I originally purchased this because I needed something that was about 5$ to make my order eligible for same day shipping. Well I'm so happy I ordered this because my 7 year old is doing swim lessons with school and this is the first sunscreen that she can actually apply by herself and doesn't burn her eyes or make her skin cold in the morning. We will be switching over to this now and I'll be purchasing another one for her for summer camp! It's so good that it doesn't have aerosol which they say is not good for us.

Works! No white face or red eyes!
Size: 0.5 Ounce (Pack of 1)
This works well. Doesn’t leave your face white and doesn’t get into eyes. Perfect for kiddos in sports. Also great you can purchase with HSA.
