Some people love summer. Some definitely don’t. But even then, there’s a consensus that cooling down in the water is the best part of the season.
That’s why we’ve selected brands we trust that offer swimwear. Most make their swimwear from ECONYL® and rPET, while others use deadstock synthetic fabrics. Some are certified PFAS-free, which is a significant advantage, as these chemicals have been linked to cancer, kidney disease, and hormonal disruption. All of the brands are transparent about their material composition and production facilities.
We hear you: open-loop recycling is not ideal, as it removes the original material from a closed recycling stream, which can otherwise be repeated almost indefinitely. However, there is no shortage of plastic waste. Our oceans are littered with discarded fishing nets that entangle and kill marine life, and there are more than enough PET bottles for everyone to recycle. In reality, only around 30% of PET bottles are recycled1, while globally just 6% to 10% are recycled in a closed-loop bottle-to-bottle system2. Around 85% of recycled PET (rPET) is instead processed in an open-loop system3 .
Wherever possible, let’s support brands that are actively championing transparency, reducing their environmental impact, and contributing to social and environmental wellbeing.
Ruby Moon‘s crowdfunding campaign for the world’s first recyclable swimsuit is still underway. Take a moment to watch Jo-Anne Godden’s message. If you believe in the project, support the campaign and help spread the word.
