12 Affordable Eco Friendly Swimwear Brands For Every Body (2023)

Looking for affordable eco friendly swimwear that won’t break the earth or your budget? Here are 12 brands to pick from.

Granted, in 2023, finding affordable eco-friendly swimwear for every body type is certainly not the Herculean task it once was. Just a few years ago, we had to force ourselves to dive deep (pun intended) into the ethical fashion rabbit hole, just to find a selected few brands able to fulfill our need for that sustainable-swimwear fix. 

Now? Ethical biodegradable swimwear and recycled swimwear crafted from natural fibers, sustainable materials, fabric scraps and even regenerated fibers are widely available to help us lower our carbon footprint and look darn good while doing so. We definitely owe this shopportunity to the stellar sustainable brands that refuse to further harm the environment with synthetics.

But why opt for affordable sustainable swimwear when there are so many fast-fashion brands ready to outfit me with a new swimsuit? We hear you ask. Along with the seemingly alluring $10 price tag comes a huge environmental impact as well as many social concerns. 

What is the environmental impact of fast fashion and fast swimwear?

You probably already know that swimsuits, in most cases, are made from synthetic fabrics such as like nylon, polyester, and spandex because they can easily wick moisture and stretch to offer that “perfect fit.”

However, the water footprint of polyester can be as high as “71,000 cubic metres per tonne of fiber” according to the Water Footprint Network. And the dying process is no different. Unlike sustainable fabrics, synthetics can take up to 200 tons of freshwater, for every ton of dyed fabric. The wastewater from the dying and production process is then dumped into nearby rivers.

On top of that, every time you wash those man-made fabrics, the microfibre particles are “swimming” right back into the ocean through our washing machines. On average, between 200 000 and 500 000 tonnes of microplastics from textiles enter the marine environment each year. In fact, today, 1.5 million trillion microfibers are “living” in the ocean, and tiny plastic fibers have also been found in our drinking water.

Then, there is the issue of textile waste. Synthetic fibers can take 200+ years for materials to decompose in a landfill. During the long decomposition process, these discarded fabrics generate greenhouse methane gas and leach toxic chemicals and dyes into the groundwater and our soil.

To put this into perspective, recent U.S. landfills alone released an estimated 109.3 million metric tons of carbon dioxide equivalent to methane into the atmosphere in 2020 — methane is more than 25 times as potent as carbon dioxide. Exposure to these gases can result in mood changes, slurred speech, vision problems, memory loss, nausea, and many more issues.

The best sustainable swimwear brands, however, manage to create a wide range of styles with the highest quality at many price points. Here’s why affordable eco-friendly swimwear matters.

What should you consider when picking out eco friendly swimwear? 

What materials are eco friendly swimwear made of?

Sustainable bathing suits have nothing in common with the chemical-packed, highly-polluting fast fashion swimwear. Some brands recycle plastic bottles And other ocean waste to then create brand new styles.

ECONYL, in particular, reduces the global warming impact of nylon by up to 90% compared with the material from oil. REPREVE is also made from 100% recycled plastic waste from post-consumer plastic bottles. Other brands, like BOLD swim, utilize all-natural materials as well as biodegradable nylon fabric. 

Last but not least, hemp is a fantastic fabric used by many ethical swimwear brands as it requires only ¼ of the water it takes to grow cotton, yet produces 250% more fiber. 

Sustainability Certifications  

Sustainable clothing is created ethically and consciously, hence most brands have the necessary certifications to back it up. Don’t fall victim to greenwashing! Your next favorite affordable eco-friendly swimsuit should have at least one of the following certifications:

  • Fair trade: It ensures that set of standards are met in the production and supply of a certain piece of clothing. This includes workers’ rights, the safety of the factories, and fair deals for farmers and workers in developing countries.
  •  Okeo-tex: This is the world’s best-known label for textiles tested for harmful substances. Sustainable swimsuits that are okeo-tex certified have been found to be non-hazardous end-products.  
  •  GOTS: GOTS-certified organic ensures that a piece of clothing meets or exceeds some strict includes social and ecological criteria in the entire textile supply chain.
  •  ISO 14001: This certification is accredited to brands that actively try to reduce their environmental footprint by adopting an effective environmental management system.

The Labor Practices

It’s no secret that the fast fashion industry employs more than 300 million people in the whole world but doesn’t pay living wages.

Even in Los Angeles, more than 50,000 mostly immigrant women were found working in clothing factories in which 85% of those facilities were accused of violating labor laws, federal wage, and hour laws.

That’s why it’s important to choose eco-friendly brands backed up by fair trade to ensure that every part of the supply chain is closely monitored. 

The Manufacturing Process

Most sustainable brands adopted the small-batch manufacturing method, to ensure less waste. On top of that, companies have already started using green energy to run their facilities as well as energy-efficient machines.

Also, ethical brands have started recycling or re-using effluent water from processing which is already due to the use of natural dyes. In sustainable fashion production, organic and natural materials are used, which means that they require significantly less water and energy and don’t create any microfibers that pollute our water bodies. 

Giving Back

Last but not least, before you opt for affordable eco-friendly swimwear, make sure to give your hard-earned money to sustainable fashion brands that give back to the community.

This means that with each purchase you make, a percentage goes into a mission they care for deeply whether it’s environmental or social causes.
