When have there been wheat suits?
weat suits? sweat suits....? wet suits.....?
i'm assuming you mean wetsuits... if so, they are made out of a thin material called neoprene and contain spandex. The spandex allows the suit to stretch, and the neoprene preserve body heat by the nitrogen gas bubbles contained inside this synthetic rubber. The gas a low thermal conductivity, meaning that body heat trapped between the body and wetsuit is not lost to the water outside the wetsuit. Depending on what type of suit you by, some incorporate different wools and fibers to retain more heat.
