There’s nothing like a refreshing dip on a warm day. But conventional swimsuits use synthetic materials like virgin nylon that releases microplastics into the ocean as you swim. So what’s a sustainable swimmer supposed to do? Buy eco-friendly swimwear!
Sustainable swimwear brands use recycled fabrics to create swimwear that protects our oceans instead of polluting them. Plus, they use eco-friendly and fair labor practices to make swimwear you’ll be proud to wear! With billions of pounds of trash entering the ocean every year, everyone has to do their part.
I’ve rounded up the best sustainable swimsuits from swimwear brands that use certified materials like regenerated nylon made from plastic waste like old fishing line. Shopping sustainable swim has never been so easy!
