My favorite sunscreen
Size: 7 Fl Oz (Pack of 2), Style: SPF 70 (Pack of 2)
Protects quite well and still working while working out. Feels like a cream instead of a thin lotion.

Thickkkkkkkk
Size: 7 Fl Oz (Pack of 2), Style: SPF 70 (Pack of 2)
This sunscreen worked well when we went to a clothing optional beach in 101°f weather - neither my husband or I burned at all and I spent most of the time in the water! My friend and her husband used a way more expensive brand and both burned.
This stuff is thick. It sits on the skin even after being in the water and isn't super easy to get off. The second time I applied it I went back into the water and tried to kind of wash it off of my hands and it wouldn't come off at all, so my hands had a visible thick layer on them the entire 2 hours I swam. I even used sand and rubbed my hands - nothing. I finally had to use a baby wipe and then wash with warm water and soap twice in an actual bathroom to get it off, but since it was all over my skin it also got all over my husband's brand new car and isn't easy to clean off.
We will definitely use it again because the protection was worth it, but maybe use it a little more sparingly! I have a tendency to slather it on because I got so burnt last year I had blisters and needed rx burn meds and iv fluids to recover 🤣
