Looking for the best eco friendly swimwear for your holidays? Look no more!
By Chiara Spagnoli Gabardi
How would you define eco friendly swimwear?
Hmm. There are many takes on this.
Most people would immediately say it would involve organic materials, such as hemp or organic cotton. But here’s the thing. If you wear swimwear made out of 100% organic cotton or hemp, it gets soaked. Sags. And possibly falls right off. Especially if you are swimming!
Unfortunately, if you want your suit to keep its form and stay on your body, you will need some kind of synthetic, such as nylon or elastic.
So what’s the most ecological way to obtain those materials? Through recycling, of course!
The only problem? When washed, these materials DO shed microparticles of plastics. We’re not gonna deny that. But the sad reality is that most recycled plastic ends up being a product that doesn’t get much use. Think: plastic bags or packaging. After all that effort, all that recycled plastic just gets thrown away after one use.
So it seems to us to be a wonderful idea to create something much more long lasting from discarded synthetic materials. Something like…swimwear!
From Waste To Wow
Luckily today, there are loads of stylish, sexy brands using not only recycled plastic bottles, but also nylon fishing nets, carpets and other recyclable textiles to create sleek, sexy eco friendly swimwear for every body type.
These brands are helping to clean up the oceans (many actually upcycle ocean waste in their creations) to bring eco friendly swimwear to the masses.
But that’s not all! Eco friendly swimwear brands today are also using upcycled and recycled fabrics. Think: bits of material that would otherwise go to landfill. They’re also using sustainable materials like organic cotton and linen, too!
From the teeniest, weeniest bikinis to outfits that are a bit more modest, here I’ve selected what some of the best sustainable swimwear options for any beach holiday, any time, anywhere. I have rated them by price:
Low: up to $100 Medium: $100-$150 High: Over $150
Now grab your basket bag, SPF, and enjoy the gorgeous weather!

Vitamin A produces eco friendly swimwear that can best be described as the water-ready equivalent of Audrey Hepburn’s classic Little Black Dress. In fact, the brand has created what it calls the “Little Black Bikini”. This is no ordinary swimsuit: its seams lie flat against the skin, avoiding unsightly bulges and ‘elastic tattoos.’
Why we love it: This is one of the pioneering brands in eco friendly swimwear. The founder designed the brand’s main fabric herself: EcoLux™ — the first premium swim fabric made from recycled nylon fibers.

By recycling already existing nylon, they do two great things. First, they avoid creating more nylon and further filling our landfills. Secondly, they are also able to clean up the oceans and save natural resources that are required in production of virgin nylon, like water and oil.
What we love: Each item is made ethically in Bali. Remnant’s seamstresses receive double the minimum wage, free health insurance, and work in a happy family-like environment.
