Good protection, water resistant
Size: Pack of 1
I love their products. This is no exception. Used it recently in the Caribbean and Florida. Did a great job of protecting my lips and also seemed to have some resistance to washing off when I was swimming or snorkeling.

This lip balm has worked well for me overall
Size: Pack of 1
This lip balm has worked well for me overall. It does what I want from an SPF lip balm and I have not had any major complaints using it. The only minor downside is that it is a little soft, so when you first start using a tube you may notice a few small chunks on your lips. That has not been a big enough issue to bother me much, but it is worth mentioning. Aside from that, it has been a good product and I would keep using it.

Feels great, no taste, no white cast
Size: Pack of 1
I tried this after reading the great reviews, and because the 3-pack was so reasonably priced. I love this stuff! My new favorite lip balm. It goes on smooth, not shiny, not chalky or white, has no scent or noticeable flavor (NOT MINT, YAY!), not sticky, and it seems to stay on well. I will definitely be ordering this product again!

No need to reapply as often
Size: Pack of 1
I don’t have to reapply as often as I did with the better known brands. Works well.
