Should a sauna suit be worn over clothes?
What to wear under your Sauna Suit
The ideal clothing to wear under your suit is a thin cotton long
sleeve tee shirt, and some thin cotton long pants. An affordable
solution to this is to dig out an old set of cheap pajamas. This
will make the wearing of the suit more comfortable and will provide
a barrier between your skin and the vinyl, thus preventing the suit
from sticking to your skin
