Awesome value for quality Banana Boat sunscreen
Size: 24 Ounce (Pack of 1), Style: SPF 50
Inside the package you get 2 sprays and 1 lotion, each 8oz. For the price, you really can’t beat it. Banana Boat is a staple sunscreen especially for my nieces and nephews who can go through a bottle of sunscreen in just a couple weeks. I like the lotion for base layer, and spray for reapplication when they don’t want to sit still, haha. The sport formula is great, it blends and goes on without much hassle. Definitely sweat resident too!

Excellent Coverage and Very Easy to Apply
Size: 6 Ounce (Pack of 2), Style: SPF 50, Size: 6 Ounce (Pack of 2), Style: SPF 50
I bought this Banana Boat Sport SPF 50 spray about six months ago, and it has worked perfectly for all my outdoor activities. It provides strong and reliable sun protection, even on very sunny days, and I really appreciate that it protects from up to 98% of burning rays. I’ve used it at the beach, walking outdoors, and even on long days outside, and I haven’t experienced any sunburn.
The spray format makes it very easy to apply—quick, even, and mess-free. It absorbs fast without feeling sticky or heavy on the skin, which is something I love because I don’t like sunscreens that leave a greasy layer. It’s also water-resistant, so it stays on even when I sweat or go into the water.
Overall, this sunscreen is ideal if you want strong protection, easy application, and a formula that feels comfortable on the skin. I would definitely buy it again and recommend it for anyone who spends a lot of time outdoors.

29 years of riding a Harley, THIS is the best sun protection I have found for long SUNNY day rides!
Size: 6 Ounce (Pack of 2), Style: SPF 50, Size: 6 Ounce (Pack of 2), Style: SPF 50
This is my "Go To" Sunscreen of choice that I find is the best to quickly spray my arms down good before a long Harley Motorcycle ride! I have tried many brands and styles from creams to face specific to lip balm but this one can does it all in my case! I quickly spray my arms ( no rubbing in required ) and a quick spray in my hand and I then rub my nose and ears , face and i'm ready to ride and I am protected! Most times I only apply this product once a day and works better than anything else for my needs. I am light skin but I have ridden lots this Summer and my arms never burn and now have a deep tan as we are entering fall...
I made the mistake of trying a store brand that looked like this product but was oily and never used it but once!
This Banana boat once sprayed on my arms, I never think about it again as its gone but still protecting my skin!
This is the best I have found after 29 years or riding a motorcycle to protect my skin with the least amount of trouble , No strange or tropical smell, NO greasy feel just quick applied lasting sun protection that has proven itself mile after mile! The BEST Sun product I have found!

It is quick to apply and I've never gotten a burn with it. It doesn't leave marks on my clothing.
Size: 6 Ounce (Pack of 2), Style: SPF 50
I've used this product for years. I spray it into my hands to apply so it doesn't go out into the air. I have never gotten a burn with it and it is. so easy to apply. I don't have to worry about white marks in my clothes. It doesn't take long to apply.

Affordable and Effective
Size: 6 Ounce (Pack of 2), Style: SPF 50
It’s really good for the price and super easy to apply. I would recommend having someone help with your back or harder-to-reach areas, because any spots you miss will definitely show if you’re out in the sun for a while. I’ve used this for a couple of years now, and it’s one I keep going back to. If you have more sensitive skin, there may be better options out there, but I personally haven’t had any issues with it so far.
