Did you know that no jellyfish, even the big ones, can sting through something as thin as pantyhose? Lifeguards in jellyfish infested waters used to wear them and invented the body skin. They are like extremely thin wet suits. No thermal protection, but complete skin protection.

....coats herself in cooking oil under her dive skin.....

Wouldn't just the dive skin do the job?

There is no way I 'm wearing cooking oil and pantyhose to take a dip on a hot summer day.

I don't get the cooking oil, but a body skin is not warm. The alternative is to avoid the water altogether, which is hotter.
