Sustainable Swimwear: The 5 Sea Friendly Brands You Need to Know This Summer

Supporting the best sustainable swimwear brands that create timeless and flattering pieces that will take you from poolside to the beach and back again.

The days are getting longer and warmer down here in the southern hemisphere, which can only mean one thing: summer is just around the corner. Summer isn't summer without a new swimwear piece to show off, right?

Here you'll find our ultimate go-to guide to getting you ready before the summer heat really heats up! Whether you're looking for bikinis, one-pieces, or anything in between, you can find it here! First, let's talk about sustainability before we look at the perfect swimsuit.

Swimwear is often made from plastic-based materials such as nylon, polyester, and spandex. These fabrics are practical, but they are also detrimental to the environment because, when washed, they release microfibre particles. The tiny plastic particles known as 'microfibres' are released into the air and wastewater systems, and then into our rivers and oceans.

Obviously, your swimwear should flatter you and feel comfortable, but we encourage you to shop consciously this season. To make this happen, you should investigate the brand's sustainability practices, check out the fabrics they use, and learn about their supply chain.  

Question: Are they supporting local businesses and workers? Is their manufacturing process transparent?

We know conscious shopping can sometimes feel overwhelming, so we've simplified it by revealing our top beach-worthy sustainable swimwear brands that incorporate more eco-friendly materials such as ECONYL, hemp and recycled nylon into their collections. You're welcome!

Zulu and Zephyr


Zulu and Zephyr are one of Australia's most loved lifestyle brands, born almost ten years ago in Bondi Beach. They aim to make a positive impact on their customers, the Planet, and their team. 

These are some of their current practices:

With the launch of ECONYL in 2020, they have saved 28000 barrels of crude oil and 26040 tonnes of Co2 emissions. (ECONYL is a 100% regenerated nylon fibre made from post-consumer nylon waste such as carpets and fishing nets.)

Zulu & Zephyr has been a proud member of 1% for the Planet since 2020.

Their bio garment bags are made predominantly from corn starch and the binding agent's Polylactide (PLA) and Polybutyrate Adipate Terephthalate (PBAT).



Bondi Born

Bondi Born's mission? "To empower and inspire the summer style of women all over the world while never compromising on quality, people or planet."


With that in mind, there are a few things to highlight from their ethos:

Every fabric is consciously sourced for sustainable certification. 

Each piece is painstakingly fitted and refitted to perfect its cut. 

Each trim is hand-selected or custom made. 

Each garment is expertly crafted here in Sydney.

Oh, and they are a B-Corp business looking to continue to find ways to give back to the people and the Planet on their unique journey.



Peony Swimwear

 Peony has its roots in nature, founded along the Australian coastline and named after the bloom that signals the beginning of summer. Their relaxed approach to fashion and everything they create? It is to consciously be part of ongoing reflections and constant progress towards sustainability, inclusivity and transparency. 

Since 2019, they are proud to consider 100% of their swimwear fabrics as recycled content, with a deep love for all things sustainability within their materials, design, manufacturing and after-care.

Fella Swim

FELLA celebrates the female form with premium swimwear that enhances and endures. FELLA founders created the brand from a desire to have different swimwear choices that looked and felt unique while referencing some of the things they loved the most: retro lines, 90s minimalism, and a Mediterranean holiday mood. 

They have a partnership on the line with Future Neutral to enable customers to offset the associated carbon emissions of their purchase at checkout. And are advocates of small-runs and made-to-order where possible to avoid production waste.

"I was so inspired by the feeling of contentment and confidence I felt while I was there. I loved the way I was free of all judgement & was truly enjoying the moment and celebrating life's beauty in all its forms. I wanted to bring that feeling to me every day and wanted other women to feel that same healthy, confident zest for life when wearing LE MÓN. It's more than a name or a place; the meaning of LE MÓN stems from a feeling." Brooke Hogan, Founder of LE MÓN. 

LE MÓN is a synonym for lasting luxury; why? Their process making is all about high-quality luxury and durable fabrics with timeless styles bound to stay on our wardrobes from season to season.

What do you need to know from the LE MÓN range? Their swimwear pieces are softly made from luxurious Italian-made recycled fabric & are self-lined in Sydney by two different suppliers. And only partner with ethical and responsible manufacturers that have obtained certifications to ensure every supplier follows ethical work practices.
