Here’s the thing you should know about shopping for sustainable bathing suits. You can’t get any made without petrochemical-based synthetics. We’re 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.

You’ve probably seen some crocheted bikinis made with cotton, but unfortunately, once that crochet cotton gets wet, it stretches out. EcoCult founder Alden Wicker once complained to a brand that makes crochet bikinis, and was told it’s not supposed to go in the water. So, for adventures in the pool, ocean, river, or cenote, you’ll find yourself wearing synthetic. 

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 and safe 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 toxic chemicals. Finally, avoid bathing suits that boast quick-dry properties — that is often achieved using PFAS, a class of chemicals that have been linked to a host of health issues, including higher risk of obesity, several kinds of cancer, and fertility issues. 

Lucky for you, there are many 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.

Remnant is an L.A.-based high-quality, sustainable swimwear brand that creates designs out of upcycled nylon. Its rescued nylon comes from ghost fishing nets, ocean-bound plastic, and textile remnants that go through a complex regeneration process to become a soft, sustainable fabric. Remnant’s bikinis are manufactured in Bali and its seamstresses are paid double the minimum wage, receive free health insurance for themselves and their families and free meals at work. All dyes used in the production of the fabric and packaging are toxin-free and are environmentally friendly. Instead of being petroleum-based, these dyes are water or soy-based and do not emit harmful substances when they break down. Remnant’s packaging is biodegradable and home-compostable-certified.


Carve Designs

Carve designs is a lifestyle beachwear brand that sells apparel that’s perfect for enjoying the outdoors. The brand makes 100% recycled plastic swimsuits in a variety of styles, including classic one and two-pieces, swim shorts, and long sleeve swim shirts in dozens of bold colors and prints.

Designed and made in New York City, REVVV SWIM is a sustainable active swimwear brand created by fashion industry veteran Cristina Aguayo.

REVVV SWIM blends style and athleticism to create a versatile one-piece suit that suits the beach and the city. Its one-piece suit is timeless, classic, and made from 100% recycled nylon.

Mara Hoffman

Mara Hoffman, a climate-neutral New York-based brand, partnered with Pyratex, a natural materials company, to create bio-based swimsuits that have the functionality of synthetics without the harmful impact. The fabric, Pyratex Power 3, is made from dissolved wood pulp from sustainably managed forests which is converted into a versatile fiber using a low-toxicity solvent. However, the fabric still contains about 11% elastane. According to Vogue Business, while the fabric has been tested in both chlorine and saltwater, the fabric has a very different feel from regular synthetic bathing suits. If you do decide to try this line of swimsuits, please report back!



OOKIOH makes “modern swimwear with a splash of nostalgia.” The materials are sourced from an Italian mill and are 100% regenerated (meaning they come from the ocean and post-consumer waste).
