TL;DR
Many traditional swimwear pieces are made from petroleum-based plastics like nylon and polyester. This article highlights 11 brands offering eco-friendly, recycled, and innovative swimwear options, emphasizing sustainability and circular practices.
Many swimwear items are made from synthetic, petroleum-based fibers such as nylon and polyester, which contribute to plastic pollution. However, a growing number of brands now offer environmentally responsible alternatives made from recycled plastics, bio-based materials, and circular manufacturing processes, helping consumers reduce their ecological footprint while enjoying the beach.
Several brands are using recycled synthetic fabrics like Repreve, Econyl, NetPlus, and Evo, which are produced from plastic waste such as fishing nets, bottles, and other discarded plastics. These materials are often certified by organizations like Oeko-Tex, ensuring they are free from harmful substances. For instance, Wallien’s Yemaya swimsuit is made from Econyl, a regenerated nylon, and remains durable after frequent use.
In addition to using recycled materials, some brands focus on circular practices, including take-back schemes and repair initiatives. Companies like Epoch Biodesign and Worn Again are developing new methods to recycle nylon and polyester textile waste into new fabrics, aiming to create a closed-loop system that minimizes waste. Niche brands such as Junk LDN and Finisterre are also designing for durability and active use, with features like UPF protection and support for watersports.
Several brands emphasize transparency and social responsibility, with some donating proceeds to marine conservation efforts or sourcing materials directly from fishing communities to prevent ecological damage. These efforts reflect a shift towards more sustainable fashion choices in swimwear, aligning environmental concerns with consumer demand for quality and style.
Why Responsible Swimwear Matters for the Environment
The shift to eco-friendly swimwear reduces reliance on virgin plastics, which are a major contributor to ocean pollution and microplastic contamination. By choosing brands that use recycled and bio-based materials, consumers can help cut down on waste and support circular economy initiatives. This movement also encourages the fashion industry to adopt more sustainable manufacturing practices, ultimately leading to less environmental harm and healthier oceans.

Growing Trends in Sustainable Swimwear Manufacturing
Traditional swimwear is predominantly made from nylon, polyester, and elastane, which are derived from fossil fuels. These materials are durable but pose environmental challenges due to their non-biodegradable nature and the pollution generated during production and disposal. Over recent years, brands have increasingly adopted recycled fabrics like Econyl and Repreve, which are made from recovered plastics, to address these issues. Certification schemes like GRS (Global Recycled Standard) and Oeko-Tex help verify the sustainability claims of these fabrics. Initiatives promoting recycling, repair, and circular design are gaining momentum, reflecting a broader industry shift towards responsible fashion.
“Better swimwear should first and foremost mean longer lasting and higher quality. Recycled fabrics like Econyl and Repreve offer a lower environmental impact while maintaining durability.”
— Helen Lofts, circular economy advocate

Current Challenges in Scaling Sustainable Swimwear
While many brands are adopting recycled and innovative materials, challenges remain in scaling these solutions across the entire industry. Recycling textiles from mixed fibers is complex, and some brands may still rely on non-sustainable practices due to cost or supply chain limitations. Additionally, consumer awareness and willingness to pay a premium for sustainable options vary widely, which can hinder widespread adoption. The long-term durability and performance of some recycled fabrics are also still being evaluated in different environmental conditions.
