Our Favourite Sustainable Women’s Swimwear Brands

This hot summer weather has us daydreaming of warmer climates and planning our holiday wardrobe. Here are some of our favourite sustainable swimwear labels for the beach, the pool, or simply sunbathing in your garden. 

It feels like spring and summer are finally on the horizon, and that means it’s almost time to to get our sustainable swimwear out of storage. Unfortunately, conventional swimwear is often made from synthetic virgin materials such as nylon and polyester, but luckily, there are lots of brands making the most of incredible material innovations or natural fibres to facilitate the transition to more sustainable swimwear – from nylon made with fishing nets to a fibre from castor beans.

With sunshine on our minds right now, here are our favourite sustainable swimwear brands to dive into this season.


Founded in 2016 by Scandinavian duo Anna and Henna, OHOY make swimwear from 100% ECONYL® regenerated nylon. ECONYL® yarn is made from nylon waste ghost fishing nets recovered from landfill and the oceans. When purchasing one of their swimsuits 1% of sales go to the non-profit Organization Healthy Seas in support of volunteer divers that help recover said fishing nets before they are sent to the regeneration facility. 

Natasha Tonić

Natasha Tonić makes ethical swimwear from a unique, natural hemp fiber that is anti-microbial, UV resistant and durable. The hemp swimsuits can also double as lingerie, bodysuits or even activewear since it’s a completely natural fibre – the perfect addition to your capsule wardrobe.


Brazilian brand Florita makes sustainable beachwear that is ethically produced under Fair Trade working conditions and created with Amni Soul Eco®, a biodegradable environmentally friendly polyamide yarn. All pieces are made locally in Rio de Janeiro contributing to the community through job opportunities. The beautiful, vibrant colours are achieved by dyeing with recycled water and water-based dyes. 

Mara Hoffman

US based brand Mara Hoffman makes her iconic swimsuits in ECONYL® regenerated nylon too.

Read more about how Mara set up the eponymous brand in our Bringing Business To Life interview.

Mylo Beachwear

Mylo Beachwear make crochet swimwear hand-made by artisans in Mallorca. Each piece is made individually upon request, so no two pieces are the same and you will have to wait for the estimated manufacturing time. The pieces are all made from OKEO-TEX certified cotton.
