Explore →SIRÉNA creates beautifully crafted, sustainable swimwear with an exceptional fit — designed to help women feel confident, comfortable and effortlessly elegant. Every piece is thoughtfully made with both style and wellbeing at its core, combining timeless design with conscious craftsmanship.
Crafted from ECONYL® regenerated nylon and lined with certified organic cotton, our swimwear is free from microplastics and toxic, hormone-disrupting chemicals where it matters most. Because true luxury is never just about how something looks — it is about how it is made, how it feels against your skin, and the confidence it gives you every time you wear it.
Sustainability sits at the heart of everything we make. Every SIRÉNA piece is designed to be worn for years, not seasons — considered in its materials, gentle on your skin and kinder to the ocean it was made for.
Our swimwear is crafted from ECONYL® regenerated nylon, a fabric spun from reclaimed fishing nets and other nylon waste recovered from the sea. It performs like the finest virgin nylon, but it takes waste out of the water rather than adding to it.
Every piece is lined with GOTS-certified organic cotton, so there is no plastic against your skin where it matters most. The cotton is grown without synthetic pesticides and certified from field to finished garment.
We produce in small batches, made to order wherever we can, so we are not left with unsold stock. Our packaging is plastic-free and recyclable, and we send nothing out that you cannot put straight into your paper recycling.
We are not perfect, and we would rather be honest about that than claim otherwise. We are working on every part of the process, one step at a time, and we will keep telling you exactly where we are up to.
