In this article you will discover the 10 best sustainable swimwear trends for 2025, including tips for stylish combinations and everything you should know for your next beach holiday.
What makes swimwear sustainable?
Sustainable swimwear is far more than a short-lived trend. It represents a new awareness that combines style, environmental friendliness, and social responsibility. Those who choose sustainable bathing suits are selecting swimwear that impresses on every level – from the material to fair production. Especially for families and all age groups, there are now suitable solutions available, such as matching swimwear for children and adults, as well as versatile ponchos, kimonos, and beach towels for the beach or the indoor pool.
Materials and fabrics: From recycled nylon to organic cotton
The foundation of sustainable swimwear is innovative, eco-friendly materials. Recycled nylon (e.g., ECONYL), recycled polyester, and organic cotton are particularly popular. These fabrics impress with their durability and comfort. Sustainable bathing suits thus not only offer a pleasant feel but also reduce the ecological footprint. Families benefit from skin-friendly fabrics that are also suitable for children. Ponchos, kimonos, and beach towels are also increasingly made from sustainable fibers and can be ideally combined.
Production processes: Fairness, transparency and environmental sustainability
The production of sustainable swimwear relies on fair working conditions and transparent supply chains. Certified production facilities ensure the efficient use of resources such as water and energy. Transparent brands openly communicate where and how their products are manufactured. Families who choose sustainable products support fair wages and environmentally friendly processes. Local manufacturing is also becoming increasingly important to reduce transport distances and emissions.
Certifications and seals: What to look out for?
Meaningful certificates and seals help when buying sustainable swimwear. Labels like OEKO-TEX Standard 100 or the Green Button stand for tested freedom from harmful substances and fair production. Anyone interested in sustainable bathing suits should look for these certifications. This resource offers a comprehensive overview of sustainable swimwear materials and relevant seals. It helps you keep track of things in the jungle of labels.
Durability and quality: Investing in sustainable products
Sustainable swimwear is characterized by its long lifespan. Robust seams and durable fabrics ensure that your favorite pieces last for many seasons. Sustainable ponchos, kimonos, and beach towels also score points for their quality and versatility. Families can save money and reduce waste by choosing durable products. Investing in sustainable quality means actively contributing to environmental protection and enjoying your swimwear for years to come.
Environmental impact: Reduction of microplastics and waste
Sustainable bathing suits make a significant contribution to reducing microplastics and textile waste. The use of recycled materials means less plastic waste is produced. High-quality fabrics shed fewer fibers during washing. Families who use sustainable swimwear and accessories actively support environmental protection. Reusable products like ponchos and beach towels also help reduce single-use consumption.
Social responsibility: Fair working conditions and local manufacturing
Social aspects are a key element of sustainable swimwear. Brands prioritize fair working conditions, safe workplaces, and fair wages in production. Local manufacturing strengthens the regional economy and ensures short supply chains. Families and individuals who choose sustainable swimwear, ponchos, or kimonos support a socially just textile industry. Transparency and commitment from brands are crucial in this regard.
Example statistics: Share of recycled materials in the swimwear industry in 2024
According to recent industry reports, the share of recycled materials in the swimwear industry rose to over 40 percent in 2024. More and more manufacturers are relying on sustainable raw materials to meet the demands of sustainable production. This trend is particularly evident in the sustainable bathing suit segment. Accessories such as ponchos, kimonos, and beach towels are also increasingly being made from recycled fibers, further amplifying this positive impact.

What should you look for when buying sustainable swimwear in 2025?
When buying sustainable bathing suits in 2025, there are several important criteria that are crucial for making an informed decision. Those who value style, the environment, and social responsibility should pay particular attention to certain features.
Seals of approval and certificates: Navigating the label jungle
Certification labels like the Green Button or OEKO-TEX offer reliable guidance when buying sustainable bathing suits. They guarantee that the products have been manufactured according to high environmental and social standards. Look for these labels when shopping to ensure that your swimwear is truly sustainable.
Transparent brand communication and origin
Transparency is paramount when it comes to sustainable bathing suits. Brands should disclose where and how their collections are produced. Inquire about the origin of the fabrics and the production conditions. Especially with matching swimwear for children and adults, like that offered by Main Design, transparency is a sign of genuine responsibility.
Fit, comfort and functionality
Besides sustainability, fit remains crucial. Look for comfortable cuts that perform well both on the beach and in the pool. Functional details like adjustable straps or high-quality fabrics ensure that sustainable bathing suits are also enjoyable for everyday wear. Try on different styles to find the perfect fit for your needs.
Price-performance ratio and durability
Sustainable swimwear is often an investment. However, high-quality materials and careful craftsmanship pay off. Products like sustainable ponchos, kimonos, or beach towels can be combined in many ways and will last for several seasons. Make sure your sustainable bathing suit is not only fashionable but also durable and robust.
Second-hand shops and swap meets as alternatives
Those who want to conserve resources can also look for sustainable swimwear on second-hand platforms or swap meets. There, you can often find nearly new sustainable bathing suits at attractive prices. This helps to further reduce the ecological footprint and extend the lifespan of the products.
Return and repair options
Another selection criterion is fair return and repair options. Many sustainable brands offer repair services for their swimwear. This way, your favorite piece lasts longer and you avoid unnecessary waste. Check the manufacturers' service offerings before you buy.
Example: Testimonials and customer reviews
Read customer reviews before buying. Testimonials provide valuable insights into the quality, comfort, and durability of sustainable bathing suits. This will help you make an informed decision and benefit from the experiences of other environmentally conscious buyers.
The impact of sustainable swimwear on the environment and society
Sustainable swimwear is significantly changing the fashion industry. Sustainable bathing suits not only offer stylish designs but also tangible added value for the environment and society. The shift towards greater responsibility within the industry is evident on many levels.
Reduction of plastic waste and microplastics
A key goal of sustainable bathing suits is to reduce plastic waste in the oceans. By using recycled materials such as ECONYL® or recycled polyester, fewer new plastics are produced. This reduces the burden of microplastics that are released when washing conventional swimwear.
Innovative production methods also contribute to minimizing material consumption. By using durable fabrics, sustainable brands extend the lifespan of each garment and thus reduce waste. In this way, sustainable bathing suits actively protect the oceans and promote a more conscious use of resources.
Promoting fair working conditions and local production
In addition to environmental protection, many manufacturers of sustainable bathing suits prioritize fair working conditions. Transparent supply chains and local production ensure that labor rights are respected. Brands like MAIN Design and Stay Wild Swim consciously choose to produce in Europe or the UK to guarantee short transport routes and better social standards.
Supporting local businesses creates new jobs and strengthens the regional economy. Consumers who choose sustainable bathing suits contribute to making fair wages and safe workplaces the standard in the fashion industry.
Fundraising campaigns & social projects (e.g. Healthy Seas)
Many sustainable swimwear brands are socially committed. They support projects like Healthy Seas, which retrieves and recycles ghost nets from the ocean. In this way, sustainable bathing suits make a direct contribution to protecting the oceans and reusing valuable resources.
Some brands donate a portion of their revenue to environmental organizations or support educational initiatives for children. Through targeted fundraising campaigns and partnerships, sustainable fashion becomes a tool for positive social change.
Raising consumer awareness
Sustainable bathing suits raise awareness of fashion's impact on the environment and society. Through transparent communication and educational campaigns, brands demonstrate the importance of sustainable consumption. Influencers and designers present innovative collections that show how style, function, and responsibility can go hand in hand.
Consumers who choose sustainable swimwear inspire those around them to make environmentally friendly choices. This creates a movement that extends far beyond the beach.
Positive examples from the industry
More and more labels are focusing on sustainable concepts. MAIN Design, for example, combines matching swimwear for children and adults with sustainable ponchos, kimonos, and beach towels. These products can be combined in a variety of ways at the beach or in the swimming pool, demonstrating that sustainable bathing suits are attractive for the whole family.
A look at sustainable beach towels and accessories reveals how diverse and thoughtfully designed modern collections are. Such examples motivate other companies to pursue sustainable paths.
