Dive Deep into Sustainable Swimwear by Making Waves with these 20+ Ethical Brands

Updated: Dec 1, 2023

Summer is just around the corner, which means it's time to start thinking about swimwear. But before you rush out to buy the latest trendy bikini or one-piece, have you considered the environmental impact of your swimwear choices? Traditional swimwear production can be harmful to the environment and even your health, but there's a solution: sustainable swimwear. Made from eco-friendly materials and produced with ethical and environmentally responsible practices, sustainable swimwear offers a way to look good while doing good. In this blog post, we'll explore the world of sustainable swimwear, from the materials used to the benefits of making the switch, and even some tips for maintaining your eco-friendly swimwear. So, let's dive in and learn more about sustainable swimwear!

What is wrong with regular swimwear

Regular swimwear may be fashionable and functional, but it comes with a hefty environmental cost. The vast majority of traditional swimwear is made from synthetic materials, such as polyester and nylon, which are derived from petroleum and take hundreds of years to decompose in landfills. These materials release harmful microplastics into our oceans and waterways, contributing to the alarming rise of plastic pollution. Additionally, the manufacturing process of traditional swimwear involves toxic chemicals and dyes that can harm both the environment and workers' health. In short, regular swimwear is a major contributor to the global plastic crisis and unsustainable fashion industry practices. It's time to make the switch to sustainable swimwear and make a positive impact on the planet.

In addition, regular swimwear is not built to last in harsh aquatic environments. A prolonged exposition to chlorine and salt can compromise the strength of the fibers and promote the breaking. The sun is a problem too. Ultraviolet rays damage the structure of plastic, making fibers more brittle and prone to breaking. This not only releases microplastics into the ocean but also results in traditional swimwear being disposed of after just a few wears, further contributing to the textile waste issue. Sustainable swimwear, on the other hand, is designed to be durable and long-lasting, making it a more sustainable and eco-friendly choice.

What makes Swimwear Sustainable?

What makes swimwear sustainable is its commitment to eco-friendliness from production to disposal.


One of the key components of sustainable swimwear is the use of eco-friendly materials. Instead of relying on traditional materials like polyester and nylon that are harmful to the environment, sustainable swimwear brands opt for materials like recycled plastics, Repreve, and Econyl. These materials not only reduce the amount of waste produced by the fashion industry but also have a smaller carbon footprint, making them a more environmentally conscious choice. Plus, these sustainable materials are often softer and more comfortable, making for a more enjoyable swim experience.

What is Econyl?

Econyl is a game-changing material that's revolutionizing the sustainable swimwear industry. This innovative fabric is made from 100% recycled nylon waste, including discarded fishing nets and other nylon scraps. But what makes Econyl truly remarkable is its regenerative properties - it can be infinitely recycled and turned into new products, without any loss of quality or performance. This means that Econyl swimwear not only helps reduce plastic pollution and waste but also promotes a circular economy that minimizes the use of new resources and lowers the carbon footprint of the fashion industry. With Econyl, sustainable swimwear is not only stylish and comfortable, but also a powerful force for positive change.

What is Repreve?

Repreve another amazing material when it comes to sustainable swimwear. It is a high-performance, eco-friendly fiber made from recycled plastic bottles that would otherwise end up in landfills or oceans. By using Repreve in swimwear, designers can create products that are not only stylish and functional but also environmentally conscious. Repreve has quickly become a popular choice for sustainable swimwear due to its versatility, durability, and softness. Some brands use Repreve in 100% of their swimwear collections, showing just how committed they are to reducing their environmental impact. So, if you're on the hunt for sustainable swimwear that looks good and does good, Repreve should be on your radar.

Why natural materials are not suitable for swimwear

While natural materials like organic cotton, bamboo, and linen may seem like eco-friendly choices for swimwear, they are not suitable for prolonged exposure to water and sunlight. Natural materials absorb water, which makes them heavy and can cause chafing and discomfort when wet. They also take a long time to dry, which can lead to odor and bacteria growth. Additionally, natural materials are not resistant to the damaging effects of UV rays and saltwater, which can cause fading, discoloration, and deterioration of the fabric over time. For these reasons, sustainable swimwear brands opt for synthetic and recycled materials that are specifically designed to withstand the harsh conditions of the ocean while minimizing their impact on the environment.

Social responsibility

When it comes to sustainability in fashion, social responsibility is a crucial factor to consider. Sustainable swimwear is not only about reducing the environmental impact of production and waste but also about ensuring fair labor practices and supporting the communities involved in the production process. By choosing swimwear brands that prioritize social responsibility, you can feel good about your purchase knowing that the workers who made your swimsuit were treated fairly and received a living wage. Additionally, some sustainable swimwear brands also give back to the communities they work with, supporting initiatives such as education and environmental conservation. By prioritizing social responsibility, sustainable swimwear can truly make a positive impact on both the planet and the people involved in its production.

How to take care of your sustainable swimwear

Taking care of your sustainable swimwear is not only important for prolonging the lifespan of your favorite swimsuit but also for reducing the environmental impact. On average, sustainable swimwear fabrics release 0.0035% weight per weight (which means 0.0035 g microfibres per 100 g of fabric) microplastic fibers per wash. This means that even sustainable swimwear can shed microplastics into the water system if not properly cared for. To help prevent this, it's recommended to hand wash your swimwear in cold water with a mild detergent and avoid using fabric softeners or bleach. By taking the time to properly care for your sustainable swimwear, you can help reduce the environmental impact and enjoy your swimsuit for seasons to come.

How to extend the lifespan of your swimwear

One of the best things about investing in sustainable swimwear is that it's made to last. However, like any piece of clothing, it requires some TLC to ensure that it stays in great condition for as long as possible. To extend the lifespan of your sustainable swimwear, start by rinsing it with fresh water immediately after swimming to remove any salt, sand, or chlorine that can damage the fabric. Then, avoid wringing out your swimwear or putting it in the dryer, as this can cause the fibers to stretch and lose their shape. Instead, lay your swimwear flat to air dry in the shade, and avoid exposing it to direct sunlight or high heat. Finally, be sure to follow the care instructions on the label, and never use bleach or fabric softeners, as these can harm the environment and your swimwear. By taking these simple steps, you can enjoy your sustainable swimwear for many summers to come!
