It’s officially swimwear season! Lazy days sitting at the beach or by the pool are a dream if you have the right suit. Finding a well-made swimsuit that fits the way you want it to and is sustainably made can be a challenge, we know! But don’t worry, we’ve got you –– and as much skin as you want –– covered.

Why consider sustainable swimwear?

It can be difficult enough to find a swimsuit you feel comfortable in, and sustainability often goes by the wayside when it comes to swimsuit shopping. Thankfully, there are sustainable swimwear brands out there creating cute and comfortable swimsuits for all shapes and sizes of bodies. Eco-friendly materials derived from recycled fabrics not only create comfy, stretchy swimwear but also divert waste from oceans and landfills, promoting a circular fashion loop that’s much better for the planet. Some eco-friendly materials you might find in your swimsuit include plant-based polyamides, ECONYL®, and recycled poly. Sustainable swimwear brands also prioritize ethical and fair production practices, ensuring their supply chain is as sustainable as possible and that workers receive fair wages and safe working conditions. 

Our criteria:

We’ve rounded up the brands that hit that sweet spot between mindful production and comfy, substantial swimwear. Whether you’re looking for a more supportive bikini, a burkini, or anything in between, you’re sure to find something in the below brands’ swimsuit collections.

When actress Jessica Rey couldn’t find a one-piece swimsuit that she loved, she decided to make her own.

The brand uses 100% regenerated material like fish nets, and all of their pieces are cut and sewn at their Los Angeles factory, meaning all their suits are made ethically and are designed to last for years and years (so you don’t have to buy a new suit every season!).

TomboyX creates gender-neutral swimwear, undies, and activewear.

And it’s all gender inclusive, featuring pieces like unisuits, swim shorts, swim tanks, and swim racerbacks, plus plenty of fun patterns (jellyfish or narwhals, anyone?). TomboyX is a certified B-Corp, and they make their swimwear from a stretchy, quick-drying, eco-friendly, and UPF 50 material.

And you can find plenty of trendy silhouettes, too, meaning you can keep your suit simple or opt for a cute one-shoulder or ruffled neckline. Comfortable fits are what Summersalt is all about — they used measurements from 10,000 real women to create their sizing, and they have a handy “butt coverage guide” to help you find the look you’re going for.

Patagonia is known for its durable outdoor clothing, and, as of September 2022, all of the company’s profit that doesn’t go back into the business goes instead to environmental initiatives.

Customer Review | “With the desert sun gnawing at your skin year round as I have, especially when swimming, having a swimsuit that covers your skin is a must, no matter how much sunscreen you think you have on. Perfect torso length, high cut but not too high cut legs, easy to zip up the back (love the long zip handle), great coverage. Havent had a suit this comfortable EVER” – Hannah (Read all reviews.)

Their packaging is 100% recyclable and plastic-free, and the company is Certified Plastic Negative.
