IT does protect from the sun.
Size: 5 Fl Oz (Pack of 1), Style: SPF 50
It protects from the sun without a doubt and lasts well. The downsides are that it leaves a greasy and "white" residue that no matter how much you rub it in.....it stays there. I use it when I am working outside and not planning on going anywhere anytime soon.

Great Sunscreen
Size: 7 Fl Oz (Pack of 1), Style: SPF 50
I cannot sing enough praises for Coppertone SPORT Sunscreen SPF 50 Lotion! This sunscreen is an absolute game-changer for anyone who loves outdoor activities. Here's why I think it deserves five stars:
Effective Protection: Whether I'm hiking, swimming, or playing beach volleyball, I trust Coppertone SPORT to keep my skin shielded from harmful UV rays. The SPF 50 protection gives me the confidence to enjoy the sun without worrying about sunburn.
Water Resistance: One of the standout features of this sunscreen is its water-resistant formula. It stays put even during sweaty workouts or dips in the pool, ensuring continuous protection throughout all my outdoor adventures.
Non-Greasy Formula: Unlike some other sunscreens that leave a greasy residue, Coppertone SPORT absorbs quickly into the skin, leaving it feeling smooth and hydrated without any stickiness. It's perfect for those who dislike the heavy feeling of traditional sunscreens.
Long-Lasting: I appreciate how long-lasting this sunscreen is. I can apply it in the morning before heading out for a day of activities, and it provides reliable protection for hours on end, saving me the hassle of frequent reapplication.
Suitable for Active Lifestyles: As someone with an active lifestyle, I need a sunscreen that can keep up with me. Coppertone SPORT ticks all the boxes with its durable and sweat-resistant formula, allowing me to focus on enjoying my time outdoors without constantly worrying about sun protection.
Overall, Coppertone SPORT Sunscreen SPF 50 Lotion has become a staple in my outdoor gear arsenal. It's dependable, effective, and comfortable to wear, making it a must-have for anyone who loves to stay active under the sun. I highly recommend it to fellow outdoor enthusiasts!

Perfect size and amount for family travel
Size: 3 Fl Oz (Pack of 6), Style: SPF 50
My usual brand raised its prices, leaving me in a bind to find a cheaper alternative that works well and is suitable for our family trips. I stumbled upon this brand and decided to give it a try. The travel-sized multi-pack is priced reasonably, and I received it promptly. I’ve decided to make this brand my go-to for travel products.
