Eco-friendly Swimsuits: Discover the Best Sustainable Swimwear Brands on Amazon


As we approach the summer season, it’s important to consider our impact on the environment when choosing swimwear. The fashion industry is notorious for its negative impact on the planet, with tons of textiles ending up in landfills every year. 

Sustainable swimwear, on the other hand, is designed with eco-friendly materials, production methods, and certifications that minimize its carbon footprint. An increasing number of ethical fashion brands are offering swimwear options that are both stylish and sustainable – from bikinis made from recycled fishing nets to one-pieces crafted from regenerated nylon. 

Choosing swimwear that is both fashion-forward and eco-friendly is not only better for the planet, but it also helps to support brands that prioritize sustainability in their practices.

Why does it matter?

Swimsuits are a summer staple, but not all swimsuits are created equal. Purchasing a sustainable swimsuit can have a significant positive impact on the environment. Here are several compelling reasons why buying sustainable swimsuits matters.

Reduced environmental impact

The traditional manufacturing process of swimwear uses a significant amount of fossil fuels and releases harmful chemicals into the environment. Sustainable swimsuits are made from eco-friendly materials such as recycled polyester, organic cotton, and bamboo, significantly reducing the harmful environmental impact.

Avoidance of harmful chemicals

Conventional swimwear production involves the use of harmful chemicals such as chlorine and dyes that pose significant health risks to workers in manufacturing plants and potential wearers. Sustainable swimsuits are manufactured using non-toxic dyes and chemicals that are gentle on the environment and safe for humans.

Reduced plastic waste

Traditional swimsuits are made from synthetic materials that do not biodegrade and release microplastics into the environment. These microplastics are harmful to flora and fauna, especially marine life. Choosing to buy sustainable swimsuits made from recycled materials helps reduce plastic waste and protect our environment.

Decreased carbon footprint

The carbon footprint of traditional swimwear is high as it relies on petrochemical-derived fibers. The production of sustainable swimsuits involves fewer greenhouse gas emissions and less water usage than conventional swimwear production.

Support for Ethical Supply Chains

Sustainable swimsuits are often manufactured using ethical supply chains that prioritize fair pay and safe working conditions for workers. By purchasing sustainable swimwear, you are supporting the humane treatment of workers and fair trade practices.

Eliminates disposable culture

Sustainable swimwear is built to last, meaning it can be worn for years. Purchasing sustainable swimwear encourages wardrobe longevity and supports circularity, where materials and resources are kept in use for longer.

By making a conscious effort to choose sustainable swimwear, we can all play a role in protecting our planet and preserving its natural resources.

What are the characteristics of sustainable swimwear?

Eco-friendly certifications

When looking for sustainable swimwear options, it’s important to consider certifications, such as Oeko-tex-certified fabrics, ethical manufacturing, and fair labor certifications. Here is a list of some certifications to look for when shopping for sustainable swimwear:

Oeko-Tex Certified

Oeko-Tex certification is considered the gold standard in the textile industry. It guarantees that no harmful chemicals have been used in the manufacturing process of the fabric. This includes the chemicals used in dyes and finishes. Oeko-Tex-certified swimwear is safe for both the wearer and the environment.

Fair Labor Association (FLA) Certified

The Fair Labor Association (FLA) is an industry-leading organization that promotes fair labor practices in global supply chains. FLA-certified swimwear guarantees that workers involved in the production of bathing suits have been treated fairly. This certification ensures that workers have access to safe working conditions, fair wages, and other benefits they are entitled to.

Bluesign Certified

Bluesign certification ensures that environmental and social criteria are met by textile manufacturers. This certification evaluates the manufacturing process’s environmental impact, including the materials used, the energy consumption, and the waste generated. Bluesign-certified swimwear guarantees that the production process has met high environmental standards.

Global Recycled Standard (GRS) Certified

Swimwear made from recycled materials can reduce the environmental impact of the fashion industry. The Global Recycled Standard (GRS) certification ensures that swimwear has been made from recycled materials in an environmentally friendly and socially responsible manner.

Fair Trade Certified

Fair Trade certification is given to products that have been produced in a way that provides fair prices and better working conditions for producers, farmers, and workers involved in the production process. Fair Trade-certified swimwear guarantees that workers have been paid fair wages and that environmental and social standards have been met.

Swimwear fabrics

Sustainable swimwear has been gaining popularity due to the increasing demand for eco-friendly and ethical fashion. The fabric used in sustainable swimwear plays a significant role in reducing environmental impact and promoting ocean conservation efforts. Here is a well-researched list of fabrics used in sustainable swimwear:

  • Recycled Nylon Fabric: One of the most common fabrics used in sustainable swimwear is recycled nylon. This material is made from post-industrial and post-consumer waste such as fishing nets, carpets, and discarded clothing. It requires less energy and resources to produce than virgin nylon and reduces the amount of plastic waste in the ocean.
  • Regenerated Nylon: Regenerated nylon is a sustainable material that is produced using discarded fishing nets and other nylon waste. This type of fabric is biodegradable, which means it breaks down naturally in the environment without causing harm. Regenerated nylon is also a durable and stretchy fabric that is perfect for swimwear.
  • Naturally occurring materials: Several other materials are being used in swimwear, including organic cotton, hemp, bamboo, and Tencel. These materials are all-natural and biodegradable, making them an eco-friendly alternative to synthetic fabrics. These fabrics also require less water and energy to produce, reducing their carbon footprint.
  • Other Sustainable Fabrics: Swimwear made from fabrics, such as linen and silk, is a sustainable option. These fabrics are lightweight, breathable, and soft, making them ideal for swimwear. They are also biodegradable and renewable, making them a great choice for those looking to reduce their impact on the environment.

These materials reduce plastic waste, require less energy to produce and promote biodegradability, making them a better choice for both the environment and consumers.

Sustainable packaging

Swimwear is an essential part of any summer wardrobe, but the packaging it comes in often goes unnoticed. Unfortunately, most swimwear packaging is not sustainable and can contribute to the growing plastic waste crisis. 

However, ethical manufacturing practices can help reduce the amount of plastic waste produced and curb the impact on the ocean.

When choosing swimwear, it’s essential to consider the packaging it comes in. Opting for brands that prioritize sustainable packaging can go a long way in reducing plastic waste. Ethical manufacturing, which prioritizes the protection of the planet and people, should also be a key consideration.

A significant portion of the plastic waste produced each year comes from packaging. According to the Ellen MacArthur Foundation, by 2050, there could be more plastic than fish in the ocean. This bleak reality highlights the urgency of reducing plastic waste in all sectors, including swimwear.

Instead of traditional plastic bags, brands are exploring alternative packaging options, such as biodegradable materials or using recycled materials. For example, some companies are using compostable bags made from natural materials like cornstarch or paper.

Additionally, some companies have implemented innovative measures to reduce packaging waste. For example, some brands utilize minimum packaging options or use recycled and recyclable materials for their product packaging.

When choosing swimwear, consumers can also consider purchasing from brands that practice ethical manufacturing. This involves adopting environmentally-friendly business practices, such as using renewable energy and reducing waste.

Brands that choose ethical manufacturing prioritize the health of the planet and its inhabitants. Through their actions, they make a significant impact on reducing plastic waste and preventing harm to marine life. By choosing brands that prioritize sustainability and ethical manufacturing, consumers can make a positive impact, both for themselves and the planet.
