This sauna suit is a two piece, heavy-duty suit, made of vinyl and is designed to retain body heat.

Vinyl is an "effective sweat aid which uses natural body heat generated from any type of low or intensive high-energy physical exercise to increase perspiration during your work out."

According to the merchant, this vinyl suit helps with the "dehydration process" through which "perspiration stimulates the entire body, thus helping to rid the body of excess water weight gain, and evenly melt... away unwanted body fat."
