All materials in some way or another take from our lovely planet, but some are a lot more sustainable and less destructive than others. For those looking to tread a little lighter knowing they’re wading blue waters with a swimwear brand sourced from sustainable materials, know that there are a number of brands out there that have taken extra measures to create high-quality, eco-minded textiles, as well as seek production facilities that support fair trade and safe labor.
Whatever your needs and wants may be, there is an entire pod of sustainable swimwear lines out there. These brands are doing their part in encouraging fellow saltwater dwellers and wave chasers to dive into the world of slow fashion, and to take action around the critical issue of responsible consumption. From design and production to packaging, distribution and partnerships, these are the best swimsuit brands that are making a serious splash in minimizing their carbon footprint while maximizing their positive social impact, giving us all the more reason to get a little wet and wild.
This classic, ribbed two piece comes in many different colors. Get the bottoms here. What we love most: The sculpting swimwear has sizing that’s incredibly inclusive and diverse, and the tank top gives your bust extra support.
Materials: 83% recycled polyester, 17% spandex
This Southern California brand has been paving the way for plant-based bikinis and bodysuits, from high-performance, recycled materials such as BioSculpt® (the world's first premium swim fabric made from plant-based fiber, especially breathable for water and workouts) and EcoLux® (made from a recycled nylon and Lycra® blend, providing a hella stretchy, butter-smooth fit). Plus other innovative textiles trailblazing the fashion sector such as EcoRib® and EcoTex®.
And whenever possible, Vitamin A works with vertically integrated facilities, so everything from dyeing to knitting is done in one location. For some products that cannot be made in California, it partners globally with fair trade artisans to produce materials ethically, and in safe working conditions. Meanwhile, Vitamin A’s partnership with 1% For The Planet gives back a portion of every sale to environmental organizations that protect our oceans (such as Oceana, Surfrider Foundation, Greenpeace, Women’s Earth Alliance and more).
Looking for something bright and playful? Tropic of C makes a mighty fine bikini top, and we can’t get enough of this bright color. It’s also reversible so you get two tops in one. Available in XS-L.
Materials: 80% polyamide, 20% elastane
Eco-lifestyle brand, Tropic of C, is the brainchild of supermodel and philanthropist Candice Swanepoel. Born with the health of the planet in mind, the super sexy swimwear line is inspired by Swanepoel’s life spent at the beach, growing up in South Africa. The former Victoria's Secret Angel is more about ethical purpose and positive impact than glittering garter belts and bedazzled C-cups these days (not that there's anything wrong with the latter!).
A direct-to-consumer brand, Tropic cuts out the middleman so it can offer fair pricing for incredible quality. It continually aims to reduce the environmental impact of production by implementing sustainable fabric development and refining its manufacturing processes to its partnerships/programs that support women around the globe. It also commissions products from artisan groups in the developing world. Made from 100 percent recycled materials such as fishing nets, fabric scraps and industrial plastics rescued from landfills and oceans, bikinis are made ultra-durable so all styles maintain their shape over time.

Professional surfer and 11x World Champion (the GOAT really, if you ask just about anyone), Kelly Slater and creative director John Moore set out to change the clothing industry with outdoor brand, Outerknown. Having pioneered many new ideas for sustainable surfwear design, they were the first to launch ECONYL® clothing, turning nylon waste like carpeting and fishing nets into endlessly organic and regenerative fibers. In an effort to be radically transparent, the site also publishes its supplier list, showing a global network of manufacturers and makers who share its values and abide by the strict guidelines of Fair Labor Association (FLA), Bluesign, and Fair Trade (for select partners). Its swim line is made of 80 percent recycled and regenerated nylon, 20 percent spandex, and a bonus of UPF 30 to 50+ sun protection.

Founded in Indonesia, Faithfull the Brand has care, quality and authenticity weaved into its fabric. From day one, it’s collaborated with Bali’s best manufacturers to create hand-made, hand-dyed and hand-printed garments. At the heart of the brand are thoughtfully produced, socially responsible designs that evoke a sense of summer and a spirit of travel. The ECONYL® Nylon for Fathfull’s retro-chic printed swimwear is collected from landfills and oceans around the world. Garments are also lined from 90 percent REPREVE® recycled polyester and 10 percent Certified Elastane.

Designed by hand in the coastal slice of heaven known as Byron Bay, Australia, Spell is the epitome of slow fashion, with some pieces taking up to a year from sketch, and being sent overseas for final production by its SAI-approved Swim Partner in Dongguan, China. Crafted from 82 percent recycled Polyamide (to promote circularity by turning waste into resources), and 18 percent elastane (for a comfy stretch), you'll find what you need and then some (although the styles are very curated).
Mix and match florals and animal prints for a bit of playful fun. All styles come digitally printed, which means Spell is able to produce intricately and precisely detailed prints using less water, less energy, less ink and less of a risk of chemical runoff to the environment (compared to conventional screen printing methods). Spell saves up to 95 percent of water usage and reduces energy consumption up to 75 percent.
Patagonia is no stranger to eco-minded consumerism. And expanding into swimwear has never been smarter for the ever-popular outdoor brand. Using 87 percent recycled nylon made from post-industrial waste fiber and discards from weaving mills and post-consumer fishing nets, Patagonia’s swim comes with an added punch being Fair Trade Certified™ sewn.
Incorporating as much recycled nylon and polyester as it can in its products lessens its dependence on virgin petroleum as a raw material source, reduces greenhouse gas emissions from manufacturing, and helps to eliminate discarded material that would otherwise end up in the open ocean with our many marine friends. So far, Patagonia has kept 527 tons of plastic waste out of the world’s oceans by turning abandoned fishing nets into its sporty gear.
With a mantra as straightforward as “Clothing for Positive Change,” PrAna attracts mindful yogis, surfers, and outdoor athletes alike.

And when it comes to swimwear design, its simplistic cuts, colors and shapes are sublime.
Always quick-drying, rocking a four-way stretch UPF 50+ barrier, PrAna’s swim collection is made with a GRS (Global Recycle Standard), RCS (Recycled Claim Standard), and within a Fair Trade Certified™ Factory. The brand works closely with Linea Aqua, the first apparel manufacturing facility in the world to be certified as Water Neutral, and where the team of designers and makers take multiple trips back and forth from PrAna’s headquarters in Carlsbad, California to the factory in Hanwell, Sri Lanka to ensure consistent standards.

Inspired by coral—one of the planet's largest and most endangered ecosystems—Koraru is dedicated to circularity. The brand's stunning swimsuits are made using materials that would normally be dubbed as waste, such as fishing nets, fabric scraps, and industrial plastic.

Each suit reduces ocean plastic, champions natural resources, and promotes ethical production—can your regular swim trunks do that?
