    A favorite
    Size: 7 Fl Oz (Pack of 1), Style: SPF 30
    This is our go-to sunscreen. It has an 2020 EWG (ewg.org) safety rating of 3 (where a 1 is safest but often difficult to find and often too expensive and a 10 is the worst safety rating). We love that is not too thin or thick, so it goes on easily, and it works into your skin without leaving you white or greasy, has a neutral pleasant smell, stays on well in the water (up to 80 minutes), and is accessible (has a decent price around $1 per ounce and is easy to find in many local grocery and drug stores). It is the one my kids grab out of the pile every time! And the only reason there is a pile is that I am trying to find a sunscreen rated 1 or 2 by EWG that has all of the properties of Coppertone SPORT 30. The search continues....

    Doesn’t come of from sweat or water
    Size: 7 Fl Oz (Pack of 2), Style: SPF 30
    The only sunscreen I use. Doesn’t burn eyes, doesn’t come off in the water or from sweat. Wish it came in SPF 20.
