In essence, it’s really challenging to find a swimwear line that isn’t made of synthetic fiber (these are non-degradable fibers, as opposed to natural materials).

Even with all the efforts companies make to break free from microplastics and eradicate virgin synthetics completely from the swimwear industry, there’s still work to be done.

However, thanks to the eco-forward thinking and ingenuity of brands, post-consumer plastic bottles and fishing nets are brought back into manufacturing and recycled to be used anew in a more sustainable manner — sustainable swimwear!
