Summer 2025 is just around the corner, and sustainable swimwear is more in demand than ever. More and more people are wondering how they can make a positive contribution when buying swimwear.
Conventional swimwear causes major environmental problems such as microplastics in the ocean, mountains of waste, and high resource consumption. Eco-friendly bathing suits offer a genuine alternative that not only protects our oceans but also has many advantages for consumers.
In this article, we present the seven best eco-friendly bathing suits for summer 2025 and show how sustainable swimwear really makes a difference.
What makes a swimsuit truly environmentally friendly?
The question of what truly defines eco-friendly bathing suits is more complex than it initially appears. Sustainable swimwear combines innovative materials, fair production, high quality, environmentally friendly packaging, and genuine transparency. Only when all these aspects are met can a swimsuit be considered truly environmentally friendly.
Sustainable materials and their advantages
The basis for eco-friendly bathing suits is innovative, sustainable materials. Fabrics such as ECONYL®, SEAQUAL®, and recycled polyester are particularly in demand. These fibers are made from recycled waste, such as old fishing nets or plastic bottles. This conserves resources and reduces the need for new raw materials.
Compared to conventional fibers, recycled textiles significantly reduce water consumption and CO2 emissions. A prime example is ECONYL®: sustainable nylon made from waste , which is used in many modern eco-friendly bathing suits. Brands are increasingly relying on innovative material combinations to unite comfort, durability, and environmental benefits.
Fair production & social responsibility
Eco-friendly bathing suits are not only made from sustainable materials, but also under fair conditions. Fair wages, safe workplaces, and ethical manufacturing processes are essential. Certifications such as Fair Trade, OEKO-TEX®, and GOTS provide guidance for consumers.
Transparency in the supply chain is an important purchasing criterion. Many brands publish their production locations and ensure regular inspections. By buying eco-friendly bathing suits, consumers promote social responsibility and support better working conditions in the fashion industry.
Durability and quality
A key factor for eco-friendly bathing suits is their durability. High-quality workmanship and robust materials ensure that the swimsuits last for many seasons. This extends their lifespan and significantly reduces their environmental footprint.
Many brands offer repair and recycling programs. Easy-care fabrics that don't stretch out or fade are another hallmark of sustainable quality. Choosing eco-friendly bathing suits means investing in a durable product that brings joy and conserves resources.
Environmentally friendly packaging & shipping
Packaging and shipping also play a major role for eco-friendly bathing suits. Environmentally friendly packaging avoids single-use plastics and instead uses recycled materials or compostable solutions. This prevents unnecessary waste.
Modern brands are focusing on carbon-neutral shipping and climate-friendly logistics partners. The goal: The entire life cycle of eco-friendly bathing suits should be as low-emission and resource-efficient as possible. Conscious choices also contribute to sustainability in this area.
Statistics & Facts
The importance of eco-friendly bathing suits is demonstrated by striking figures. According to Fashion Revolution, over 8 million tons of plastic end up in the ocean every year, often through microfibers from conventional swimwear. Sustainable alternatives address this issue and prevent further waste.
According to Statista, more than 60 percent of consumers now prefer sustainable fashion products. Eco-friendly bathing suits are therefore not just a trend, but an important step towards a healthier environment and responsible consumption.

What should you look out for when buying sustainable swimwear?
When buying eco-friendly bathing suits, there are numerous aspects to consider that go beyond mere appearance and price. Those seeking truly sustainable swimwear should pay close attention to specific criteria to contribute to environmental protection and benefit from long-lasting quality.
Understanding certifications and labels
Reliable certifications are an important criterion when buying eco-friendly bathing suits. Look for certifications such as GOTS, Fair Trade, or the OEKO-TEX® Standard 100 , which guarantees textiles tested for harmful substances. These labels stand for transparent production processes and environmental compatibility.
To avoid greenwashing, it's advisable to examine the meaning of the labels. Not every label is equally meaningful. Find out which standards actually verify sustainability criteria and which serve only marketing purposes.

Fit, comfort and functionality
Sustainable swimwear often impresses with a better fit and high level of comfort. Many eco-friendly bathing suits are made from innovative fabrics that feel pleasant against the skin and offer optimal support.
Pay attention to choosing the right size and try on different cuts. A good fit not only increases comfort but also extends the lifespan of the swimsuit, as it reduces material fatigue.
Price-performance ratio
Sustainable swimwear is usually more expensive than fast fashion, but eco-friendly bathing suits offer real added value. Thanks to high-quality materials and fair production, they are more durable and retain their shape and color for significantly longer.
Invest consciously in quality, benefit from a longer lifespan, and save money in the long run. Sustainable swimwear not only benefits the environment but also your wallet.
Customer reviews and brand reputation
Genuine customer reviews help assess the quality and sustainability of eco-friendly bathing suits. Reputable brands value transparency and openly provide information about materials and production conditions.
Before buying, check the supplier's reputation. Brands with positive reviews and clear communication usually stand for responsible manufacturing and high customer satisfaction.
Return and warranty conditions
When buying sustainable swimwear online, it's worth checking the return and warranty policies. Many providers of eco-friendly bathing suits offer flexible return policies, repair services, or even recycling programs.
Pay attention to customer-friendly terms and conditions that promote sustainable practices. Good service contributes to the product's longevity and the reduction of textile waste.
Care and lifespan: How to keep your Eco swimsuit looking beautiful for a long time
An eco-friendly bathing suit impresses not only with its sustainable materials but also with its durability. Proper care is crucial to ensuring your favorite garment lasts for many summers. With a few simple tips, you can significantly extend its lifespan and further reduce its environmental footprint.
Washing and drying
Always wash eco-friendly bathing suits with cold water and mild detergent. Harsh chemicals and hot water damage the fibers and shorten their lifespan. Use a laundry bag to reduce microplastics and protect the material. Always air dry your swimsuit in the shade, never in a dryer. This will help maintain the fit and prevent colors from fading. For more care tips, see our article on sustainable surf and swimwear .
Storage and care
Careful storage is especially important for eco-friendly bathing suits. Rinse the swimsuit thoroughly after each use to remove salt, chlorine, or sunscreen. Store it only in a dry place and not in plastic bags so the material can breathe. Be careful not to twist the swimsuit too much to maintain its elasticity. This way, your swimsuit will remain beautiful and functional for many seasons.
Repair and upcycling
A small tear doesn't mean the end for eco-friendly bathing suits. Many brands offer repair services or DIY repair instructions. Loose seams or small holes can usually be easily mended. If the suit is no longer usable, you can use the fabric to create practical accessories like headbands or bags. Upcycling extends the lifespan and conserves resources.
Sustainable disposal
When your eco-friendly swimsuits have truly reached the end of their lifespan, be sure to dispose of them responsibly. Many manufacturers take back old items and recycle the materials into new products. Find out about recycling programs or donate intact swimwear to such organizations. This way, the cycle continues and you can continue to contribute to environmental protection.
The future of sustainable swimwear: Trends for 2025 and beyond
The future of eco-friendly bathing suits will be shaped by innovative technologies and rising demands. Sustainability is evolving dynamically, with new solutions constantly emerging. Those who opt for environmentally friendly swimwear in summer 2025 will benefit from exciting developments that will sustainably transform the market.
Innovative materials and technologies
In 2025, the focus will be on bio-based fibers, algae-based fabrics, and new recycling processes. More and more brands are relying on raw materials from renewable sources. Algae-based fabrics not only offer excellent skin compatibility but also a better environmental footprint.
Certifications are also gaining in importance. The Bluesign® Sustainable Textile Production System, for example, guarantees that production and materials meet the highest environmental standards. These innovations make eco-friendly bathing suits the first choice for conscious consumers.
Circular economy and zero waste
The circular economy is a key trend. More and more labels are developing closed-loop models, in which material cycles are completely closed. Old swimwear is recycled to create new products.
An excellent example is the collaboration with Healthy Seas , where collected ghost nets are used to create new fabrics for eco-friendly bathing suits. Zero-waste approaches and transparent supply chains are thus becoming the standard for responsible brands.
Personalization and on-demand production
Custom-made swimwear is a sustainable trend. On-demand production makes it possible to manufacture only what is actually needed. This conserves resources and avoids excess inventory.
Customers can choose individual eco-friendly bathing suits that fit perfectly and reflect their style. This increases satisfaction and reduces the fashion industry's environmental footprint.
Growing consumer demands
Awareness of sustainable fashion is steadily growing. More and more people are actively seeking information about the origin and production of their products. Social media and influencers are amplifying this trend and turning eco-friendly bathing suits into a lifestyle statement.
According to recent studies, consumers expect transparency, quality, and genuine sustainability. Brands that credibly embody these values gain the trust of their target audience and set new standards.
New business models
Sharing, rental models, and second-hand goods are gaining in importance. Innovative platforms make it possible to share or pass on used swimwear. Collaborations between brands and environmental organizations promote sustainable solutions and strengthen the commitment to environmental protection.
These business models offer new ways to conserve resources and extend the lifespan of eco-friendly bathing suits. In this way, sustainable consumption becomes an integral part of everyday life.
If you're now eager to dive into the water in summer 2025 not only in style but also responsibly, sustainable swimwear is the perfect choice. By choosing it, you're not only supporting the environment but also making a statement for quality and durability – values that should be important to all of us. With brands like MAIN Design, you can be sure that every piece is produced with respect for people and nature, and that a portion of the proceeds goes towards protecting our oceans.
