Sustainable swimwear: 10 brands swimming against the tide afbeelding

Finding sustainable swimwear can be a tricky task. Typically, swimwear is made from plastic-based materials like nylon and polyester. They stretch well and dry quickly. But these synthetic fibres come from petroleum and they never biodegrade.

So what’s a sustainability conscious swimmer to do? Thankfully, a number of swimwear brands and designers are creating products that are kinder to the environment and still have all the functionality you’d expect from a great swimsuit or pair of board shorts.

Here are some of the most exciting sustainable swimwear brands out there right now.

10 of the best sustainable swimwear brands

Tide & Seek

This sustainable swimwear brand makes bikinis and one pieces for women. All designs are made from REPREVE®, a polyester fibre made from 100% recycled plastic bottles. The fabric is chlorine resistant and offers UV protection at factor 50. And we love the range of patterns, all in fun pastel shades.

Arket’s sustainable swimwear for both men and women is made from recycled materials. Recovered fishing nets, discarded plastics and even old carpets are combined to make Econyl®, a form of recycled nylon. This quick drying material is then used to make Arket’s simple but stylish range of swim shorts, bikinis and swimsuits.

Sustainable swimwear isn't compromising style for ethics; it's the epitome of fashion-forward thinking. With innovative designs and materials, brands are proving that you can make a statement both on the beach and for the environment, redefining what <a href=“”> swimwear </a> truly means.

Hey   I'm August, founder of the sustainable fashion brand, Marda. Our mission is to pull plastics out of the ocean and convert it into sustainable high-quality swimwear.  We've been covered in Forbes, GQ, Borsen, Elle etc., but I spotted your article above. We're always trying to find new ways to be a part of the climate change conversation and give people more green choices.  Would it be possible to get listed alongside the other sustainable companies mentioned in the article?  We're always up for sharing it to our thousands of newsletter subscribers, social media followers, and would be sure to mention the article in our press section.  Thoughts?" Best, August Dyrberg
