Swimwear has long been a fashion staple for beachgoers and water lovers worldwide. Yet for years, the industry has been notorious for significant environmental harm—from non-biodegradable fabrics to unethical production practices. Today, conscious consumers are demanding better choices, and forward-thinking brands are stepping up with eco-friendly alternatives that don’t compromise on style or performance. This shift has given rise to some of the best sustainable swimwear brands that are not just redefining fashion but also championing environmental stewardship and ethical practices. Whether you care deeply about ocean conservation, recycled materials, fair labor, or low-impact manufacturing, there’s a brand out there for every eco-conscious fashion enthusiast.
Why Sustainable Swimwear Matters
Before we dive into the brands themselves, it’s important to understand why sustainable swimwear is so crucial. Traditional swimwear is usually made from polyester, nylon, and elastane—fabrics derived from fossil fuels that can take hundreds of years to break down in landfills. On top of that, the manufacture of these materials releases harmful greenhouse gases and contributes to microplastic pollution, which ultimately ends up in our oceans.
Sustainable swimwear brands address these problems by using recycled materials like regenerated nylon (often sourced from fishing nets or plastic waste), adopting low-waste production techniques, and ensuring transparency and fairness in their supply chains. These innovations help reduce environmental footprints and promote responsible consumption habits.
1. Patagonia
Patagonia is a leader in sustainable outdoor gear, and its swimwear line mirrors its broader environmental philosophy. Known for robust activism and eco-conscious design, Patagonia’s swimwear is made using recycled nylon and polyester. The brand also encourages repair and reuse of products to extend their lifespan.
What sets Patagonia apart isn’t just the materials but its mission-driven approach. The company donates a portion of its profits to environmental causes and openly reports its supply chain impacts, making it one of the best sustainable swimwear brands for eco-aware shoppers who want transparency and accountability.
2. Vitamin A
Vitamin A is one of the most recognizable names in sustainable fashion swimwear. Known for its chic and flattering silhouettes, the brand also offers a commitment to environmental accountability. Vitamin A uses ECONYL®—a regenerated nylon produced from pre- and post-consumer waste like fishing nets and textile scraps.
Additionally, Vitamin A prioritizes California-based manufacturing to support local workers and reduce transport emissions. Its diverse styles—from bandeaus to one-pieces, and mix-and-match separates—appeal to those who want both fashion-forward designs and sustainable materials.
3. Seafolly (Eco Edit)
Originally an iconic Australian swimwear brand, Seafolly recently expanded its commitment to sustainability through its Eco Edit collection. This line features pieces crafted with recycled nylon and polyester, reducing reliance on virgin materials.
Seafolly is also known for inclusive sizing and bold, statement-making designs that make eco-friendly choices feel empowering and stylish. With its wide variety of colors, cuts, and patterns, it’s easy to find a sustainable suit that aligns with your personal aesthetic.
4. Summersalt
Summersalt has rapidly gained a loyal following for its inclusive sizing and body-positive ethos. What sets it apart in the sustainable space is its dedication to quality and longevity. Instead of promoting fleeting trends, Summersalt focuses on versatile, timeless swimwear designed to last season after season.
Sustainable material usage includes ECONYL® and other recycled fabrics, and the brand is transparent about its sourcing and manufacturing standards. With vibrant prints and thoughtful engineering, Summersalt earns its spot among the best sustainable swimwear options available today.
5. Girlfriend Collective
Though perhaps better known for activewear, Girlfriend Collective also offers a line of swimwear that follows its eco-conscious principles. Every piece is made from recycled materials, including old water bottles and fishing nets collected from oceans.
Girlfriend Collective also champions ethical labor practices and radical transparency—providing detailed information about factories, worker conditions, and material sourcing. Its minimalist, functional designs are ideal for those who prioritize comfort and sustainability in their swimwear.
6. Eco Swim Co.
Eco Swim Co. is a newer player in the industry but has quickly made waves (pun intended) thanks to its fully sustainable and ocean-friendly approach. This brand exclusively uses recycled nylon and eco-certified dyes, and it partners with factories that meet strict environmental and labor standards.
What makes Eco Swim Co. especially noteworthy is its commitment to zero-waste packaging and minimal carbon footprint logistics. For surfers, divers, and frequent beachgoers who want their swimwear to reflect their environmental values, this brand offers both performance and conscience.
7. Hunza G
Hunza G has built its reputation on its signature crinkle-stretch fabric and timeless silhouettes. While its primary focus isn’t exclusively on sustainability, the brand uses high-quality, long-lasting materials that reduce the need for frequent replacement. Hunza G’s garments often become wardrobe staples that defy seasonal trends—supporting sustainability through durability.
Recently, Hunza G has also incorporated recycled fabrics and ethical production practices, enhancing its environmental credentials while retaining the brand’s signature aesthetic appeal.
Choosing Your Sustainable Swimwear
When choosing among sustainable swimwear options, consider factors such as:
- Material source: Recycled or regenerated fibers such as ECONYL® or recycled polyester are preferable.
- Manufacturing transparency: Brands that share where and how their products are made tend to uphold higher ethical and environmental standards.
- Durability and design: Sustainable swimwear should last multiple seasons, resisting fading and stretching.
- Corporate values: Support brands that actively contribute to environmental causes and fair labor practices.
