Sustainable Swimwear Explained

Hold up. What is eco-friendly swimwear? What’s wrong with regular bikinis?

Well, the biggie is that most swimsuits are made from plastic – specifically, nylon and polyester.

Aside from stretching out and pilling pretty quickly (especially in 100% polyester suits), these fabrics shed plastic microfibers when washed, which will eventually make their way into our oceans. No bueno.

Many eco-friendly swimwear brands use recycled post-consumer products like fishing nets and plastic bottles to make their swim fabric. 

And while microplastics are unavoidable unless you get a suit made of natural fibres, most ethical swimsuit brands include a care guide that walks you through how to wash your suits to prevent washing microplastics down your drain.

And then there's the production side of things. Fast fashion companies often make their swimsuits as quickly and cheaply as possible, without regard for worker conditions, production runoff, or final product quality.

Ethical bathing suits are made in responsible factories that minimize pollution in their process and pay their workers fairly.

Top Eco Swimwear Brands

Swimsuit shopping can be complicated; that’s why we want to help make inquiring about the brands’ ethics and size inclusivity a little bit simpler. 

With summer on the horizon, we're sharing our favourite eco-conscious swimwear and beach accessory brands that ascribe to ethical production practices. These versatile and ethical brands are making quite the splash from mix and match bikinis to one-piece and bodysuits.

It was quite the challenge to find cute, well-fitting, sustainable and ethical swimwear brands a few years back. 

Patagonia led the charge, and other conscientious brands have either evolved or sprung up to fill the gap in the affordable, sustainable swimwear market.

So how is the average eco-minded gal meant to navigate all the options?

Not to fear, I've rounded up a list of my 27 favourite sustainable swim brands to help you make a splash this summer (and the next, and the next…you get it) guilt-free!

Londre was born when its co-founders became obsessed with creating the highest quality bodywear with the lowest impact. 

Now, the brand offers one-pieces that can be worn to the beach as easily as they can be paired with a blazer. But if you’re looking for something more classic (with a twist!), opt for the high-waisted bottoms and asymmetrical tops. 

Available in bright colours and patterns, the products are made from recycled materials, sourced from an OEKO-Tex certified factory, and made to withstand salt, sand, and sweat wear and tear. 

22. REI

  • Ethics | Eco-friendly & sustainable fabrics, Fair Trade Certified, ethically made
