Who knows what the best transparent plastic pants are made of? One of my favorites is made from polyurethane and is known as Euroflex. I do not know if this is different from PVC. There must be a lot of different kinds other than just clear plastic. The Euroflex are like rubber pants and seem to last forever. What is wonderful is these plastic pants do not get hard. These also come in a variety of colors. Do you think there is a trend toward transparent plastic pants?
