9 Sustainable Swimwear Brands Waving Goodbye To Waste

Hailey Carrillo


Summer means surf, salt, sunshine, and finding the best sustainable swimwear brands.

Between wedgie-giving one pieces and non-biodegradable bikinis, traditional swimwear doesn’t fit right—for us or the planet. 

That’s why we’re diving into the growing pool of brands offering recycled swimwear that takes plastic out of our water, instead of washing it back in.

Everything we recommend to you on Sustainable Jungle is independently researched and we ask all brands to confirm their claims. To avoid waste, we test products on an as needed basis. This post contains affiliate links. If you buy something through our links, we may earn a small commission. Learn more about why we do this here.

The Best Recycled Swimwear Brands Making A Splash

We can’t overstate the need to stop relying on virgin plastics, and Understatement agrees, hence their line of recycled bathing suits made for women, by women. 

Noserider Surf Club’s swim and surf suits made of recycled nylon may help you catch a big wave, but it’s all thanks to a small supply chain located entirely in Bali.

BERLOOK’s petite and plus-size swimming suit catalog will turn heads and keep beach-goers of all shapes and sizes comfortable and confident with timelessly elegant cuts.

Paddle to the end of the article to learn how we landed on these sustainable swim brands.

About BERLOOK

Price Range: $28–$85

BERLOOK provides resort-worthy swimsuits made entirely from recycled materials.

The eco-friendly swimwear brand has several figure-enhancing fits in petite and plus-sizes, ranging from bikinis, one-pieces, tankinis, cheeky bottoms, and more.

Nothing puts us more in the mood for a quick plunge like a stylishly sexy plunge neckline.

That’s why we tested the ECONYL® Red Cutout One Piece Swimwear and loved the supportive yet stretchy fit of its mostly regenerated yarn makeup. 

If you’re more of a two-piece person, the Navy Cut Out Bikini Top and matching bottoms features a super soft and comfortable microfiber lining that mimics terry cloth so it feels like you’re always wrapped up in your beach towel.

BERLOOK’s Ethical & Sustainability Practices

Materials:

BERLOOK’s swimwear is mainly made of recycled materials.

The Ecolook collection blends 85% ECONYL® regenerated nylon with 15% elastane while most other styles utilize 95% recycled polyester and 5% spandex

Both lines feature linings made of mostly recycled polyamide, with a touch of spandex.

Supply chain & labor practices:

BERLOOK partners with garment factories across different regions, including China, Vietnam, and India. 

All of their recycled fabric factories are BSCI-certified and they’re working with all partners to obtain similar manufacturing certifications, like SA8000 and WRAP, by 2025. 

Caron commitments & green practices:

BERLOOK has repurposed over 415,000 plastic bottles and ~300 pounds of ocean-collected nylon into their recycled plastic swimsuit line. 

Each item is packaged in a reusable linen bag made from fabric scraps. They have incorporated 100% compostable bags made from plant-based materials. 

As a Stripe Climate member, BERLOOK contributes 1% of its revenue to carbon removal projects.

Inclusivity:

BERLOOK’s sustainable women’s swimwear is available in XS–XL, with an additional plus size collection in sizes 16–24.

About Noserider Surf Club

Price Range: $20–$160

Emma Bukowski started Noserider Surf Club when she realized her dream of becoming a surfer. 

The ethical swimwear brand maintains a small local supply chain for surf suits, bikinis, rash guards, one-pieces, and oversim gear.

We’ve tested the Lowback Cropped Rash Guard and commend its playful design, performance fit, and unrestricted movement.

But we especially love it for its versatility to be paired with any swimwear bottoms anytime you need a little warmth or sun protection—in addition to natural sunscreen, of course—on your upper half.

If you’re worried about burning your back still (out of sight, out of mind!), the regular Cropped Rash Guard eliminates that plunging back for full shoulder and arm coverage. It’s their standout product, and as water-sport lovers, we can absolutely see why.

Both rashguard tops are designed to have a snug fit, particuarly around the band so they won’t ever come off when surfing or doing other more rambunctious water sports, so we recommend sizing up, as we were also recommended to do. We would normally buy a small and the medium fit us perfectly in these.

Noserider Surf Club’s Ethical & Sustainability Practices

Materials:

Noserider uses the eco-friendly swimwear fabric Vita, a luxury fabric crafted from 78% ECONYL® and 22% elastane. 

It comprises the entire suit, lining included. 

Supply chain & labor practices:

Noserider keeps production close to home, meaning everything is handmade in Bali, Indonesia. 

Their manufacturing partner is female-owned and just a few minutes up the road from their flagship store. 

Caron commitments & green practices:

Noserider packages each suit in a biodegradable canvas storage bag, which only needs to travel down the road to its storage facility.

The swimsuit tags are made from recycled card paper, with recycled kraft paper hygiene liners. 

Inclusivity:

A female-founded brand, Noserider carries eco-friendly bathing suits in women’s sizes XXS–XL.

About Understatement

Price Range: $51–$116

Understatement holds a simple motto, “For women, by women.”

They have a bold collection of bras, bralettes, tops, cheeky briefs, and recycled plastic swimwear.

We strapped up the Plunge Bikini Top and the High Cut Bikini Briefs to see if they were worth their salt.

The ECONYL® fabric used for these styles is unique compared to other brands on this list because of its super soft and stretchy rib knit, which is not only flattering, but oh-so-comfortable.

Understatement uses ECONYL® recycled polyamide with minimal elastane for its entire swimwear collection. 

The linings still feature virgin polyamide, but we hope to see this turn recycled, too.

We appreciate Patagonia’s fair trade swimsuits like the Reversible Seaglass Bay Bikini made from recycled materials with some spandex. 

However, our personal favorite Patagonia piece is their 100% recycled Baggies shorts—and not just because of all the fun prints they’re available in.

These shorts are a summer staple for us because they’re made featuring quick drying swimwear fabric, yet feature a casual cut so you can wear them on land and in water alike.

Wayfarer and Baggies board shorts are made of 100% DWR-coated recycled nylon.

Caron commitments & green practices:

Patagonia has a lot of green going on, including recycling poly shipping bags in stores (eventually aiming for a biodegradable alternative), offering lifetime repairs through their Ironclad Guarantee, and selling pre-loved Worn Wear.

How We Found These Eco-Friendly Swimwear Manufacturers

Looking to take your swimwear knowledge from the kiddy pool to the deep end?

Let’s dive deep into our criteria for the most sustainable swimwear brands. 

Materials:

Unfortunately, fabric technology has yet to evolve long enough for us to strap on any organic swimwear, but recycled synthetics are making quite the splash here.

The most common sustainable swimwear fabric is ECONYL®, a regenerative nylon fiber made of reclaimed ocean plastics like abandoned fishing nets, followed by recycled polyester often made from recycled plastic bottles.

Sustainability means durability, so most still use some spandex/elastane. While rarely made of any recycled content at this time, it does increase the swimwear’s longevity. 

Supply chain & labor practices:

Being ethically made means being made safe work in exchange for fair wages. Third-party certifications help us vet these claims and keep the blue water free from greenwashing.

Caron commitments & green practices:

The best sustainable swimwear brands often use recyclable/compostable packaging, carbon-neutral shipping, and repair/recycling options. 

Inclusivity:

EVERYONE looks swimmingly swell in a cheeky bottom bathing suit, so we look for brands that provide sizes for all body types.

Community & charitable giving:

We love it when the tide comes in and a brand supports doing good through monetary donations, conservation efforts, or donations of unsold gear. 


Final Thoughts On Ethical & Sustainable Swimwear

The time to sink or swim is now.

Collectively, we need to take the plunge toward plastic-free oceans. 

If you have a functional swimsuit, keep using it until you can’t—but if those old bottoms are looking a bit baggy, one of these brands should (bathing) suit your watery ways.

Let’s channel our inner Dory and just keep swimming toward a cleaner, healthier planet by supporting eco-friendly swimwear brands swimming against the tide.
