For Professional Outdoors Folks, THIS WORKS!
Size: 5 Ounce (Pack of 1), Style: SPF 50+
I am in the sun approximately 300 days a year and I have used everything available. I am on the water daily and there are only 2 products that 1) work and 2) stay on when wet; Blue Lizard and Doo's. Both have nutrients and moisturizers keeping your skin young. This stuff WORKS! Highly recommended.

Worked well for 4 days spent poolside in 104° temps
Color: White, Size: 0.15 Ounce (Pack of 1)
I purchased this specifically for the Zinc/ mineral based SPF factor. There are not a lot of great options for a sun BLOCK lip balm. This is about the highest SPF I could find, in a tube/stick applicator. We use 70 and 50 alternatively and apply often for our bodies and face, but we needed an extra layer for the lips. (They really are very delicate tissues)
We like the texture, I didn't notice a flavor or odor, so I guess that's good right? I did not see any white cast to it and honestly I would not care if it did, I just want a sun block for my lips while we are poolside. It worked well.
A slight tingly feeling to my lips for the first 30 seconds when applying it, but it did not sting or irritate my skin/lips.
We went 4 days of poolside lounging and swimming with about 5-6 hours a day at the pool. We were in and out of the shade, in and out of the water, at at very dry desert Nevada 104° sunny location. We reapplied about every 1.5 - 2 hours, or if we felt like we needed it after eating or drinking something. We did not burn nor peel, our lips were soft and great.
I will keep using it and will likely purchase again, when needed. It's a good brand.
Aside from straight up old fashioned white or colored lifeguard zinc sticks, this is a less "clown like makeup" option.

Great Product
Color: White, Size: 0.15 Ounce (Pack of 1)
This lip balm was recommended by my surgeon to protect my lip from uv rays. Surprisingly, it does not have that yucky spf taste other lip balms have. It does create a white cast, but I find if I lightly put it on the cast is not prominent, and I am Caribbean with deep tan skin.
Very grateful this lip balm does its job!

Protect Your Lips
Color: White, Size: 0.15 Ounce (Pack of 1)
This chapstick feels great on my lips, nice smooth texture, no unpleasant taste. It definitely protects my lips from the sun. The only downside is that it has a white tint to it on my lips; I wish it were completely sheer.
