Top 20 Sustainable Swimwear Brands

posted in brand roundups

Last Updated on February 15, 2024

We’ve found sexy bikinis, full coverage one-pieces, and sporty sustainable swimwear to suit everyone. Also featured are size inclusive brands offering plus size eco friendly swimwear.

What makes a Swimsuit Sustainable?

We usually advocate for natural fabrics, however when it comes to a swimsuit synthetic fabrics offer benefits. Synthetic materials like nylon don’t retain as much water and dry a lot faster, making them more practical and comfortable for swimming – no one wants a soggy suit.

Look for good quality swimwear made from recycled materials like RPET (usually from plastic bottles) or Econyl (recycled nylon made from things like fishing nets). Also try to select a style you know you’ll get a lot of wear from and avoid trendy pieces that will only last a season.

For this roundup we also looked for sustainable swimwear brands who have a transparent and ethical supply chain with fair wages.

    It’s so cool to see more and more companies turning to recycled fabrics and materials. People often remember to shop ethically when shopping for things like food and drink, but forget about clothes and gifts- let alone swimwear! Thanks for bringing this to our attention!

    Great round-up!! My bikini pieces (I have 2 tops and 2 bottoms that can all be mixed and matched) are still in great shape but I am really looking forward to getting a more sustainable version when it needs replacement. I AM a wee bit concerned about having to shopping online though, swimsuit shopping is so hard as it is!!!

      If I’m shopping online for swimsuits I usually go for styles that have ties so they’re more flexible/adjustable, and definitely compare your measurements to the brand’s size guide and read any fit notes!
