Sustainable Swimwear Explained

Hold up. What is eco-friendly swimwear? What’s wrong with regular bikinis?

Well, the biggie is that most swimsuits are made from plastic – specifically, nylon and polyester.

Aside from stretching out and pilling pretty quickly (especially in 100% polyester suits), these fabrics shed plastic microfibers when washed, which will eventually make their way into our oceans. No bueno.

Many eco-friendly swimwear brands use recycled post-consumer products like fishing nets and plastic bottles to make their swim fabric. And while microplastics are unavoidable unless you get a suit made of natural fibers, most ethical swimsuit brands include a care guide that walks you through how to wash your suits to prevent washing microplastics down your drain.

And then there’s the production side of things. Fast fashion companies often make their swimsuits as quickly and cheaply as possible, without regard for worker conditions, production runoff, or the quality of the final product.

Ethical bathing suits are made in responsible factories that minimize pollution in their process and pay their workers fairly.
