10 Sustainable swimwear brands to make a splash this season

Sustainability is one of the most important movements permeating fashion today, and this summer brands are making a splash about swimwear too. Given how much the sustainable fashion market has grown over the past few seasons, it’s unsurprising that there are more options than ever when it comes to sustainable swimwear. Unfortunately, conventional swimwear is often made from synthetic virgin materials such as nylon and polyester, but luckily, there are lots of brands making the most of incredible material innovations or natural fibres to facilitate the transition to more sustainable swimwear.

We’ve read about sustainable swimwear in the past and learned how the majority of eco-friendly suits are made from recycled materials, meaning that they’re far more sustainable than those brands which use new fabrics.

But that was before we learned about microplastic water pollution.

As you probably know, if you’re wearing any clothing made from polyester, acrylic or any other petrol-based, plastic material, every time you wash that garment, you’re contributing microfibre pollution to the oceans. Microfibres are too small to be filtered out by waste treatment plants, so they can end up in our waterways and oceans by the billions. All of which means you’re literally swimming in the ocean wearing a swimsuit made of this toxin.

The truth is, modern swimwear and true sustainability just don’t go hand in hand — unless you’re more interested in sunbathing than swimming. In that case, no problem: there are some incredible organic cotton and hemp based swimsuits that are perfect for soaking up the rays on a sun-lounger.

But when you go for a dip, there’s a problem: those organic fabrics sag when they get wet. Sometimes, just sometimes, the water makes them so heavy that they fall off. Oops, that itsy-bitsy-polka-dot bikini moment! As yet, there isn’t a sound fabric solution for swimsuits which doesn’t result in more plastic in our oceans and landfills — but don’t worry: there’s hope!

For example, several brands are using a material called ECONYL®, which is a regenerated nylon fibre developed by global textile manufacturer, Aquafil. It’s made out of offcuts such as fishing nets, fabric scraps, carpet flooring, and industrial plastic reclaimed from landfills and oceans all over the world. That waste is sorted, cleaned, and recycled back to nylon fibre through a regeneration and purification process. It has the potential to be recycled infinitely, which helps create a more circular fashion system.

Major sportswear brands like Adidas continue to expand their ethical offerings and introduce innovative new fabrics made from recycled materials and focused on performance. Then there are the indie, boutique labels that are showing that being eco-friendly and elevated aren’t mutually exclusive objectives, as evidenced by the minimalist maillots from brands like Ohoy and Reformation — plus, the playful suits from lines like Mara Hoffman.

If you want your swimwear to be sustainable, it’s really up to you to do two key things: 1) Wash garments by hand with cold water or 2) if you use a machine, you can use a GuppyFriend- a washing bag that protects synthetic garments and reduces the amount of microfibres that may enter the water.

Here are 10 sustainable swimwear brands that are using ECONYL® or superior fabrics which we hope you’ll consider wearing this summer.

  1. Reformation

This well-loved LA based brand is best known for its upcycled deadstock fabric, but their swimsuits are constructed from ECONYL® . Taking a holistic view of sustainability with the ‘Ref standards’, they also look at garment care and microfibre shedding while stating how much carbon was saved with each style. And now, to make their clothing even more eco-friendly, they’re offering a Guppy Bag with each purchase — just pop your suit into it when you washing and all microfibres are captured by the bag. Cool!


2. RubyMoon

The world´s only not-for-profit sustainable brand using ocean plastics & empowering women entrepreneurs in 14 developing countries.

Affordable, ethical and active, this Brighton-based sustainable brand offers vibrant, high-quality, affordable swim and active wear for women who want ethical Gym to Swim wear. Whilst being made from cutting-edge sustainable materials such as ECONYL®, infused with Xtra Life Lycra that’s chlorine resistant for more than 100 hours of exposure, RubyMoon also helps women set up and grow businesses across the globe. This inspired and innovative brand is also validated to produce 42% less emissions compared to other high street swimwear by The Princes Accounting For Sustainability Project conducted by Ecodesignbloom.com. So, not only is no petrol involved in their designs but 100% of the net profits generated by RubyMoon are lent out as small loans, to empower women entrepreneurs in eleven nations. As a personal touch, the swimwear pieces are named after the women in whom we have invested- for example, Victorine, Solange & Zarina.


3. Mara Hoffman

Founded in New York in 2000, this is a truly mindful brand which continues to focus on sustainable materials, processes, and production in order to improve and extend each garment’s life.
