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.
