The conversation around sustainable bikinis and swimwear has been dominated by recycled synthetics like ECONYL and other forms of repurposed plastics. While these materials offer a step forward in reducing plastic waste, they fall short when considering the full environmental impact—particularly when it comes to microplastic pollution and biodegradability.
At Public Myth, we believe a truly sustainable bikini should be made from natural, biodegradable fibers that do not contribute to ocean pollution. This is why we have chosen to craft our bikinis using Merino Wool and a Bamboo/Cotton blend—two materials that break down naturally and offer numerous benefits for both the wearer and the planet.
The Problem with Recycled Synthetics in Swimwear
Many brands market recycled polyester as an eco-friendly alternative, but the reality is more complex. As highlighted in our article, Recycled Polyester Clothing is Not Eco-Friendly, garments made from synthetic materials still shed microplastics with each wash and wear. These microplastics inevitably find their way into our oceans, harming marine life and entering the food chain.
Even though recycled polyester gives a second life to plastic waste, it does not solve the underlying issue of plastic pollution—it merely delays it.

Why Natural Fibers Are the Answer to a Sustainable Bikini
A true solution to ocean-friendly swimwear lies in biodegradable, non-toxic fabrics. Unlike synthetics, natural fibers like Merino Wool and Bamboo Cotton decompose over time without leaving harmful residues behind.
- Merino Wool: A game-changer for swimwear, Merino Wool is naturally moisture-wicking, breathable, and offers UV protection. Unlike conventional swim fabrics, it does not shed synthetic microfibers into the ocean.
- Bamboo/Cotton Blend: A soft, comfortable alternative that is gentle on the skin and highly sustainable. Bamboo requires minimal water and pesticides to grow, making it an excellent eco-conscious choice.

The Future of Sustainable Bikinis & Swimwear
The fashion industry has long relied on plastic-based fabrics, but the shift toward truly sustainable alternatives is gaining momentum. By choosing natural fiber bikinis, we can reduce our reliance on petroleum-based textiles and help protect the delicate ecosystems of our oceans.
At Public Myth, we are committed to redefining what sustainable swimwear should be—clean, natural, and free from toxic pollutants. Join us in making a meaningful difference by choosing swimwear that truly respects our planet.
