Swim Sustainably: 21 Eco-Friendly Brands for Swimsuits Built to Last

Disclaimer: Some of the links in this post are affiliate links. If you buy something through them, I may earn a small commission (at no extra cost to you).

Let’s be honest: fast fashion swimsuits might look cute, but they’re rarely made to last. After a few dips in the pool or salty beach days, the seams start to stretch, the fabric fades, and suddenly you’re shopping for a new one next summer (or even sooner).

But there’s a better way. More and more swimwear brands are using recycled materials, ethical production methods, and timeless designs – without sacrificing style! And while the upfront cost might be a little higher than a $15 bikini from a fast fashion site, you’re investing in quality pieces that will last for years. I’m still wearing mine from three summers ago, and they look just as good as day one.

Here are some of the best sustainable swimwear brands worth checking out – mostly for women, with a few men’s options too.

Sustainable swimwear might cost more up front, but it’s often more affordable in the long run. A well-made swimsuit that lasts three or four summers is a far better investment than a $20 set you replace every year. It’s also better for the planet: less waste, fewer resources, and fewer impulse buys.

If you’re on a tighter budget, consider shopping secondhand or looking for past-season suits on resale platforms like Poshmark, ThredUp, Depop, or Vinted. You can often find high-quality products at a fraction of the original price.

However you shop, choosing swimwear that lasts is one of the best ways to keep your summer wardrobe sustainable.
