Sustainable Swimwear: 12 Ethical and Eco-Friendly Options for Summer

You must be wondering, why sustainable swimwear? What’s wrong with the regular bathing suit?

Wait, answer me, how long did your last fast fashion suit last you? I thought so. The majority of swimwear sold in fast fashion stores isn’t built to last, as enticing as it may be.

Well, the biggie is that most swimsuits are composed of plastic, notably nylon and polyester. from stretching out, pilling pretty quickly and getting dumped in a landfill, these fabrics shed plastic microfibers when washed, which will eventually make their way into our oceans.

Everyone’s to-do list must include becoming more sustainable and our closets are a fantastic place to start.

Yes, the world of sustainable fashion can be perplexing at times, but many companies are working hard to make the industry more environmentally friendly. There are many sustainable options to pick from, from wedding gown designers to loungewear companies and even jewellery; the key is to do your research thoroughly before buying.

When it comes to shopping for swimwear, this is no exception.

So, this summer, why not invest in your future travels by purchasing some long-lasting and eco-friendly bathing suits?

4 incredible fabrics that make a sustainable swimwear

There are a plethora of different fibres and textiles used to produce sustainable swimwear, so what should you look for?

Here are some of the most common sustainable swimwear fabrics that you just cannot miss on while searching for a sustainable bathing suit.


ECONYL is a type of recycled nylon that is mostly produced from fishing line and carpets. These raw materials are regenerated in a four-step process that produces the final product as virgin (fossil fuel-based) nylon.

According to the producers, ECONYL emits 90 percent fewer emissions than virgin nylon, and the fabric produced is infinitely recyclable back into new ECONYL yarn and products, enabling for closed-loop production systems.

Recycled Polyester

You’re probably already familiar with recycled polyester if you’ve ever bought something that claims to be made from recycled bottles. Polyester that would otherwise end up in landfills is cleaned, broken down into small “flakes,” melted into pellets, and then spun into yarn and weaved into garments.


You may have heard about Yulex, a new material that is gaining popularity in environmentally friendly swim suits. It is said that when you use Yulex-based materials, you don’t have to choose between performance and the planet. Yulex is sustainably produced from renewable rubber tree forests and proves to be a great alternative to petroleum-based rubbers.

Natural Fibres

Choosing a natural fabric over a recycled man-made one is arguably the best swimsuit choice for the planet. Some swimsuit designers have effectively reinvented cotton and hemp to make them more flexible and suitable for underwater usage. However, these natural textiles have a tendency to absorb water and sag or lose form over time, so mixing them with elastane is sometimes necessary to make them flexible.

When it comes to sustainability, it’s a delicate balancing act to discover something that will be long lasting while causing the least amount of environmental damage.

Sustainable swimwear brands that you just can’t miss this summer!

From mix and match bikinis to one-pieces and bodysuits, there are versatile and ethical brands that are making quite the splash.

Believe it or not, this is a new style of shopping.

Rather than opting for disposable swimwear, why not opt for these eco-friendly bathing suits that can actually withstand the test of time?

Created to be durable, functional, and built to last, swimwear from these brands isn’t just a purchase, it’s an investment into a product that you can use forever.

Everything they do is for the planet and its people!

P.S, since you’re prepping for your beach bag anyway, be sure to add some natural sunscreens, , eco-friendly sunglasses, razors and sandals to it, too.
