This is the sunscreen I've been looking for my entire life
Size: 5 Ounce (Pack of 1)
I've tried almost every sunscreen under the sun. I've used lotions, sprays, sticks, always above spf50. I apply every 2-3 hours and always after swimming. I make sure the product isn't expired and you know what I STILL GET BURNED. BUT THIS ONE- I wore it on a carribean vacation so I was out in the sun constantly and NO SUN BURN AT ALL. I've officially become a blue lizard fan and will buy nothing else. The product is thicker than traditional sunscreen and you may need more than you traditionally use but it is so worth it. The smell is very slight if at all. It did not stick to my clothes at all. I went swimming with it on and it honestly was still on even after being in the ocean. I still reapplied to be safe but I could feel the first application still on my skin. I used the lotion for all over application and the spray can to help with getting my back and reapply on my legs. I used the little deodorant stick to apply to face and ears. All were very easy to use. And that's the only downside I have. You do have to scrub a little bit to get it off at the end of the day. For me not a downside at all because I know it was worth it for the sun protection and I would have had to scrub to get all the sand off anyway.

Waterproof
Size: 5 Ounce (Pack of 1)
This product is great for kids in the pool or ocean. It is very waterproof and you can even see the water beading on top of the sunscreen. It doesn't go on super clear, which can be an advantage for determining coverage. One other unique feature is the bottle itself changes color to indicate it is currently exposed to UV light although that is basically anytime you walk outside in daytime.

Good sun protection but leaves white streaks after sweating
Size: 5 Ounce (Pack of 1)
I really wanted to like this sunscreen after seeing it make a lot of lists for best sunscreen for runners. But for whatever reason, about 15-20 minutes into my runs and I've started really sweating, I see white streaks in my elbow crease. I've started developing weird tan lines in my elbow crease if I don't consciously try to re-rub and re-spread the sunscreen in my elbows periodically during my runs. If I only use the sunscreen for lower impact activities, I don't get the white streaks. It's as if from the sweat it pools the minerals from the sunscreen into my elbow crease. But yet I don't have that problem with the sweat mix with my sunscreen on other parts of my body. I've also switched to Australian Gold Botanical Mineral sunscreen which ironically isn't meant for sports, but I don't have the elbow crease white streaks issue with that sunscreen. I will say, this Blue Lizard sunscreen does rub and spread easily and doesn't leave a white cast after rubbing it into my skin. Although it does feel mildly greasy after I'm done applying it everywhere. I've switch to Australian Gold Botanical Mineral sunscreen which doesn't feel greasy but it does leave a slight white cast on my tan skin, but I'll rather have that than deal with frequently needing to re-rub/re-spread the sunscreen in my elbow creases when white streaks form.
