Neoprene is water proof. Therefore it never sags. Neoprene is elastic. Therefore it forms to your body much like yoga pants or leggings do. Also you’ll never have to worry about a neoprene bikini slipping off. Neoprene retains color. Wash your bikini one hundred times; the color simply will not fade. It is etched into the rubber chemical compound. Neoprene is environmentally conscious. The production of neoprene produces significantly less CO2 than the production of spandex nylon (which is used to make most bikinis). In the 1950’s bikinis were made out of cotton. Today most bikinis are made from spandex nylon. Bikinis of the future will be made of neoprene. Embrace the future of bikinis.
