Here’s the thing you should know about shopping for sustainable bathing suits….

No, you can’t get ones made without petrochemical-based synthetics. I’m sorry. There are a few brands listed below that are mostly natural materials like hemp and modal. But they still contain some synthetic fibers to provide stretch.

I know you’ve seen some crocheted bikinis made with cotton, but unfortunately, once that crochet cotton gets wet, it stretches out. Believe me. I had one, and when I complained to the brand, their answer was that it’s not supposed to get wet. Oh! OK. It’s just decorative, then?

So, many conscious bathing suit brands have turned to synthetic textiles made from recycled plastics. By far the most popular fabric is ECONYL, a high-quality, Italian fiber made from upcycled nylon fishing nets, textile waste, and old carpets. Others are made with polyester from recycled PET plastic bottles.

You also want to look at where the textile is printed (in Europe or the United States is best), where the bathing suit is sewn (in a certified fair factory is ideal), and what kind of packaging the company uses, like polybags made of compostable or recycled materials. Some brands also have OEKO-TEX certification, which means the bathing suit has been tested and certified free of toxins.

Lucky for you, there are more brands popping up all the time that use recycled textiles and other sustainable and ethical manufacturing practices. So there’s no need to compromise on your style.
