What is Eco-Friendly Swimwear?

Eco-friendly swimwear is made from recycled fabrics that contribute to reducing damage to the environment. These recycled fabrics are made from materials like dumped fishing nets and plant-based materials. 

Recycling makes use of discarded materials which would otherwise end up in oceans and landfills disrupting ecosystems. Sports brands that manufacture eco-friendly swimwear apply the principles of closed-loop production to minimize or eliminate waste while promoting conservation of resources. Materials are kept within the production loop even after they are used. 

At the beginning of the closed-loop cycle is acquisition of organic or non-toxic materials that are likely to have minimal environmental impact. These materials are then manufactured into activewear using processes that generate low levels of waste with leftover fabric being reused. The activewear resulting from this process will be collected and recycled into new sports gear. These energy efficient processes greatly reduce damage to the environment.

What are the most eco-friendly swimsuit fabrics?

If the thought of enjoying your summer water sport activities in high performance swimwear that will not contribute to the destruction of the ocean that you want to enjoy the activities in, then your first step will be to get to know which fabrics you should be looking for that have respectable eco-friendly credentials. 

Following is a list of fabrics that will guarantee you sustainable swimwear without hurting our planet:


Econyl is a fiber made by recycling industrial plastic waste and old ocean fishing nets. It is remarkably similar to nylon and is sometimes referred to as recycled nylon. The process used to manufacture it uses fewer resources and produces much less waste than nylon. Since Econyl is a recycled fabric it helps reduce the waste that goes to the ocean and landfills by repurposing waste materials.


  • Econyl is not toxic and compares well to nylon which is toxic. 
  • It can be recycled several times and still remain strong.
  • This fabric has a silky texture and feels gentle on the skin.
  • It retains shape after many uses.
  • The fabric is breathable, moisture-wicking and dries quickly.
  • Econyl is not only odor-resistant but also boasts anti-microbial qualities.

It is, however, noteworthy that Econyl produces microplastics when washed. These could cause damage when they end up in the ocean.  Using a washing bag to prevent the microplastics from escaping is your best bet for not harming the planet while keeping your favorite Econyl activewear garment clean.

Organic Cotton

Cotton is one of the better known natural fibers. A lot of water and chemicals go into its production meaning significant environmental impact. Organic cotton on the other hand is produced without the use of pesticides and is therefore beneficial to the environment.


  • No pesticides or fertilizers are used in its production meaning the environment is not damaged.
  • Organic cotton boasts a major advantage for those with sensitive skin - it is hypoallergenic and generally non-toxic. It has a soft feel which is gentle to the skin as well as low friction meaning there will be no chafing.
  • It is breathable and moisture-wicking.
  • It is durable and as an added bonus if you do decide to dispose of it, you can do so without guilt because it is biodegradable.

Recycled Polyester

Recycled Polyester is created from recycled plastic bottles or industrial waste. Since no new materials are utilized, waste going to landfills is  minimized. It does not carry a huge price-tag and is therefore popular with those in search of eco-friendly activewear on a budget.


  • Recycled Polyester is moisture-wicking and quick drying.
  • It is flexible with good stretch and anti-microbial and UV protection.
  • It is non-toxic and recyclable.
  • This lightweight fabric is durable and can withstand frequent washing.

As with Econyl, recycled polyester also produces microplastics when washed and a washing bag is the best way to prevent these from damaging the environment.


Lyocell is a semi-synthetic fiber. It is a form of regenerated rayon made by dissolving wood pulp normally of the eucalyptus tree.  The pulp is dissolved in a non-toxic solvent. Lyocell is also known as Tencell which is one of premier brands of the fabric.


  • Derived from organic wood sources in sustainably managed forests.
  • Biodegradable and recyclable.
  • Involves a closed-loop system, minimizing water and energy and using non-toxic materials.
  • Flexible, lightweight and gentle on skin.
  • Does not cling and has a cooling effect.
  • It has antibacterial odor preventing properties.

What is Ethical Swimwear?

Chances are a large percentage of swimwear you will see on the beach, in shops and around pools are made from synthetic fiber like polyester or spandex which is undoubtedly popular for its water-repellant and elastic properties. 

These fibers are made from plastic sources which are major sources of pollution of the sea. Plastic is not biodegradable and can hang around landfills for hundreds of years and also clog up the ocean. 

Activewear made from plastic derived fiber produces microplastics when washed. These microplastics then travel to the sea and add on to environmental havoc. 

It is also likely that companies that manufacture products that add to pollution and environmental degradation are not practicing ethical methods of production. They are probably using sweatshops or even dabbling in child labour and do not have any recycling policy.  

Enter ethical swimwear: sports gear that is manufactured using fabrics with a low environmental impact in ethical conditions. 

The factories in which these sustainable garments are produced give workers fair wages and ensure good working conditions. They also do not get involved in illegal practices like child labour and will most likely also have a sound environmental conservation policy that takes into account recycling and reduction of carbon footprint.

Why Should You Choose Eco-Friendly Swimwear?

The main reason why you should choose eco-friendly swimwear is because it has a low environmental impact. Being good to the planet is something worth doing for yourself as well as for future generations.  The other big reason why you should eco-friendly swimwear is that the ethical practices used to produce these garments ensure that people working in the factories that make them enjoy good humane working conditions and get fair wages. 

Eco-friendly swimwear is also made from flexible breathable fabrics with features like moisture-wicking and UV protection.  Some eco-friendly fabrics like organic cotton can also be hypoallergenic meaning that those with sensitive skins need not miss out on the fun. 

If you are still looking for more reasons to choose eco-friendly swimwear you might want to consider the face that many sports brands that produce sustainable activewear have after sales services that will appeal to your ethos - they use recyclable packaging or offer to take back your garments after you have used them and recycle them. The environment benefits and you continue enjoying your swim with a clean conscience.

Is Eco-Friendly Swimwear As Durable?

Fabrics used to make eco-friendly swimwear like Econyl and recycled polyester are durable. They can withstand frequent washing and retain their shape. In most cases you can use your eco-friendly garment for a long time knowing you are helping to make the environment better while looking stylish.

Does Eco-Friendly Swimwear Fit as Well as Other Swimwear?

Eco-friendly swimwear designers and manufacturers who are in the eco-friendly community can produce garments that fit people of all shapes and sizes. Many sports brands are able to come up with designs that are customized to fit different body types and you will find that there is indeed an eco-friendly that will suit you.

Additionally, when you take a look through the benefits of the top fabrics used to make eco-friendly swimwear, you will find out that being stretchy, flexible and generally easy to work with are some of their main features.

How Do You Know If Your Swimwear is Eco-Friendly and Ethical?

A clothing rack filled with various swimsuits provoking the question of which choice is eco-friendly.

This is where you will have to apply your love for the planet and “get your hands dirty” doing some research. To be considered sustainable your garment will not only have to be eco-friendly, it must be ethically produced too. 

Using eco-friendly fabrics in a factory with bad working conditions and low wages and vice-versa is not sustainable. Both the human and the conservation aspects have to be present. 

Is It Eco-Friendly?

To determine if your swim gear is eco-friendly you will have to know what kind of fabric it is made from. The label will most likely have “sustainable” on it. There should be some indication that the fabric is recycled or possibly made from virgin sources using non-toxic additions. Be cautious about brands that claim to be sustainable and do not clarify the kinds of fabrics that have been used.

Is It Ethical?

To answer this question, you have to get curious about the business decisions that your sports brand of choice makes. Do these decisions contribute to caring for our planet or does the company want to jump on the sustainable bandwagon for marketing purposes without putting in any actual work? 

Activewear producers who pack the garment you have asked for in something recyclable are definitely making a statement about caring for our planet as are those who are committed to supporting environmental activities and causes.

How Do You Make Your Eco-Friendly and Ethical Swimwear Last and Limit Waste? 

You can make your eco-friendly garments last for a long time if you take good care of your garment. Hand washing using eco-friendly detergent is the first step. 

Eco-friendly fabrics like Econyl and recycled polyester will produce microplastics during washing and you can prevent this by using a washing bag such as the Gruppyfriend to ensure the microplastics do not go into the environment and end up in the sea.  

Additionally, do not wring or twist your garment.  Avoid the use of fabric conditioners or any other harsh chemicals. Also, do not hang your swimsuit to dry in direct sunlight or rough surfaces.
