People are becoming more and more aware of their individual impact on the environment. Increased understanding of carbon footprints has encouraged people to become more conscious of what they consume.

Unfortunately, one of the largest contributors to the collective rise of CO2 emissions is the fashion industry. Because of this, you might be looking for new ways to shop that reduce your own carbon footprint and are easier on the environment. 

One of the most common ways to shop sustainably is to shop second-hand. Thrift stores are often packed full of high-quality pieces that are looking for a second home. While second-hand shopping is a wonderful way to give old pieces new life, a thrift store might not have everything you want or need. 

While it’s easy to pick up a loose-fitting sweater at a thrift store, swimwear sits tightly on your body and needs to fit you like a glove. You will most likely need a more personalized shopping experience for swimwear than browsing in the thirst store, so consider looking for alternative materials to make shopping for swimwear sustainable. 

What Is Sustainable Swimwear?

Traditional swimwear is usually made from some type of plastic, such as nylon, polyester, and Spandex. These materials are ideal for swimwear since they are moisture-wicking, stretchy, and inexpensive to make. However, these plastics are not biodegradable, meaning they will sit in landfills and oceans forever, clogging our planet and harming marine life. 

While many brands have discovered natural, biodegradable fabrics to use for clothing, a biodegradable fabric that has all of the qualities needed for a swimsuit is still yet to be widely used. Because of this, brands dedicated to sustainability have turned to recycled plastic for their swimwear. 

While most of these new sustainable pieces are still not biodegradable, they give new life to old materials and keep tons of plastic out of landfills every year. 

Sustainable Swimwear: The Fabrics 

Designers have discovered a few different materials to utilize when creating swimwear. Here are some of the most popular repurposed materials:

What Is Recycled Nylon?

Also known as Eco Nylon or ECONYL, this material is predominantly sourced from fishing lines and carpets. Andie Swim, like many other swimwear lines dedicated to sustainability, uses recycled nylon to make their sustainable swimwear. 

After collecting the old material, the production process begins a four-step process to turn these plastics into a version that is chemically identical to virgin nylon. While there is still a manufacturing process involved, it is estimated that the emissions of creating Eco Nylon are 90% lower than those of producing virgin nylon. 

Additionally, the Eco Nylon used to create the swimwear can be endlessly recycled back into different swimwear, Eco Nylon yarn, or other new products.

Andie Swim uses Eco Nylon to create swimwear because recycling fishing lines helps further the health of the ocean, and Eco Nylon is a study material that will feel just like virgin nylon on your body.

What Is Recycled Polyester?

If you have ever seen a piece of clothing advertised as being made from plastic water bottles, it is made from recycled polyester. Polyester has a plethora of useful material benefits, such as durability and strength. These benefits stay with the materials as it is broken down into small bits, melted into pellets, formed into yarn, and used to make your swimwear. 

Polyester is a wasteful material to create: This process requires a ton of water, chemicals, and fossil fuels. The production process is toxic to water and air quality. 

An enormous amount of polyester already exists in our world, so repurposing polyester to create something is considered to be an act of sustainability. In fact, repurposing polyester creates 75% fewer COs emissions than creating virgin polyester. 


Yulex is an innovative material that is relatively new in the fashion industry that is made from natural rubber harvested from rubber trees. As of now, it is the only plant-based alternative to petroleum and limestone-based materials.

It uses less CO2 during the manufacturing process compared to synthetic fibers, but it is still able to maintain most of the benefits of nylon, Spandex, etc. Its most attractive feature is its biodegradability, which is extremely beneficial for the environment.

Yulex is not widely available or commonly used yet, so most brands are still sticking to recycled materials. 

Natural Fibers

Many production companies prefer to use natural fibers because they are biodegradable and have less of an impact on our environment. Fibers like wool and cotton decompose over the years and release much fewer levels of CO2 than synthetic materials.

Natural fibers simply do not have the features needed to create a practical and comfortable swimsuit. While some brands are attempting to reinvent cotton and hemp to make them more water-resistant and flexible, these swimsuits still feel noticeably different. 

When slipping on a cotton bathing suit and taking a dip in the water, you might notice it has quickly lost its shape and holds onto water rather than wicking it away. While a future might exist where natural materials can be engineered to mimic synthetic fibers, the most realistic sustainable option as of today is using recycled materials. 

What Is Greenwashing?

Nowadays, labeling a garment as “recycled” or “sustainable” is commonly used just as a marketing ploy called greenwashing. Companies understand that people are desperate to lower their impact on the environment, and they capitalize on this desire. If you are looking for a sustainable swimsuit, be sure to do an in-depth look at the product.

If something claims to be made from recycled materials, check the percentage of virgin vs. recycled material in the swimsuit. While it’s sometimes unavoidable for brands to use virgin plastic, there is a large difference between a swimsuit that is made up of 70% recycled and one that is only 10% recycled material.

At Andie Swim, our sustainable swimwear is made up of a significant majority of recycled materials, which dramatically reduces the CO2 emissions in production and works to protect our planet. 

How To Care For Recycled Swimwear

When we care for swimwear properly, we can reduce the microplastics released from a swimsuit and extend its life for as long as possible. The first, and most important step, is to hand wash your garments.

Hand washing will reduce the number of microplastics released and give you better control over the temperature. Always hand-wash your sustainable swimwear in cold water rather than warm or hot. 

Try to use as little detergent as possible, and avoid using fabric softener, which can break down the fabric over tie. Once you are finished washing your swimwear, lay them out to dry away from the sun. 

Lastly, while wearing your swimwear, try to avoid chemical sunscreens and opt for natural options instead. Harsh chemicals can degrade your swimwear which will cause damage to marine environments. 

  • Environmental tip: hand washing is best for garments for several reasons, including reducing the number of microplastics that could be released into our waterways. For additional environmental protection, wash swimsuits in a guppy bag. Guppy bags help prevent microplastics from escaping into the water if you must wash them in a machine.
