Best Sustainable Swimwear Brands 2025

Criteria Defining a Sustainable Brand

With the growth of responsible fashion, more swimwear brands claim to adopt sustainable approaches. But what does this really mean in the world of swimwear? Not all eco-friendly products are equal. For a brand to be truly committed, it must meet several criteria, from the materials used to production methods, including reliable certifications. Here are the key factors to consider.

Materials Used

Material choice is one of the first indicators of sustainability for a swimwear brand. Many brands favour recycled textiles or materials sourced from renewable resources to reduce their environmental footprint.

Recycled polyester: Made from PET plastic bottles or textile waste, it reduces virgin petroleum use while offering the same performance as traditional polyester.
Regenerated nylon (ECONYL®): Produced from used fishing nets, fabric scraps and other nylon waste, this material is 100% regenerated and infinitely recyclable without quality loss.
Organic cotton: Grown without pesticides or chemical fertilizers, it preserves biodiversity and farmers’ health. Though less common in swimwear, it may be found in beachwear.

These materials not only reduce waste and natural resource consumption but also extend product lifespan due to their quality and durability.

Production Process

A truly sustainable brand goes beyond fabric choice: its entire manufacturing process must minimize ecological impact and uphold high social standards.

Local or regional production: By limiting distances between production and distribution, CO₂ emissions related to transport are significantly reduced.
Reduced water consumption: Some factories use dry or closed loop dyeing techniques, cutting down on precious water waste.
Renewable energy: Some brands choose industrial partners powered by green energy sources to reduce their carbon footprint.
Packaging reduction: By opting for recycled or biodegradable bags or eliminating unnecessary packaging, brands limit waste production.
Ethical working conditions: Transparency in factories, social audits, fair wages and regulated hours are key elements that ensure products respect both people and the environment.

Certifications

Certifications help consumers quickly identify brands or products that meet certain environmental or social standards. Here are the most common in the sustainable swimwear sector:

OEKO-TEX® Standard 100: Guarantees the absence of toxic substances harmful to human health in finished textiles. This label ensures skin safety, especially for garments worn close to the body like swimsuits.
GRS (Global Recycled Standard): Certifies not only the use of recycled materials in a product but also compliance with environmental and social criteria across the entire supply chain.
B Corp: A global certification assessing a company’s social and environmental performance. A B Corp certified brand commits to transparency, responsibility and positive impact on society and the planet.
FSC® (Forest Stewardship Council): Often used for hanging tags or packaging, it ensures paper materials come from sustainably managed forests.

While not mandatory, these certifications provide an additional guarantee for consumers aiming to make informed choices.

How to Choose a Sustainable Swimsuit

Opt for timeless, well-cut and adjustable styles that don’t just follow seasonal trends. A triangle bikini top or black one-piece swimsuit will remain a safe choice year after year. Material durability is also essential. Look for fabrics resistant to chlorine, salt, UV rays and deformation. Finishes such as reinforced seams or quality linings ensure better longevity.

Care plays a key role in extending your swimsuit’s life. Good maintenance habits help preserve shape, colour and elasticity longer.

Don’t forget the ecological aspect: choose swimsuits made from recycled or certified sustainable materials. Favour brands committed to ethical, local or low-impact production. By choosing a more responsible swimsuit, you reduce your ecological footprint while investing in a piece designed to last.

Sustainable Swimwear Trends in 2025

Colour-wise, nature takes center stage: earthy tones bring an organic touch. Pastels also find their place in soft versions, while blue stands out as a symbolic nod to ocean protection.

Cut-wise, sculpting swimsuits perfect for flattering the silhouette with a natural shaping effect are popular. High-waisted bottoms remain favoured for comfort, alongside triangle bikinis with adjustable straps or tied details for optimal fit.

Eco-friendly design is evident in the details: invisible seams, tags made from recycled materials and prints inspired by marine flora and fauna.

Moreover, new eco-energy production methods are gaining ground, favouring processes with low water and energy consumption. Recycled materials, such as fibres from fishing nets or plastic bottles, are growing in popularity. These innovations contribute to more responsible fashion without compromising quality or style.
