Most of us seek out clothing made from all-natural, compostable materials that won't release microfibers in the washing machine, though that rule doesn't quite apply to swimwear.

So since bathing suits made from synthetic materials are the only functional options in 2024, there are a few other things you can look out for to keep your swimwear eco-friendly. Some companies make swimsuits out of recycled plastic, for example, while certain factories maintain strong ethical standards. But, with that in mind, keep reading for our favorite 2024 swimwear ~lewks~.

Fair Harbor makes men's swim trunks out of recycled plastic bottles, recycled polyester, and a little bit of spandex.

Additionally, Fair Harbor has a bathing suit recycling program known as the Roundtrip Initiative. Fair Harbor will email you a free shipping label, which you can use to mail in your old swim trunks in exchange for a $5 credit for each suit, with up to $25 off your next purchase. Then, Fair Harbor sends old suits to 2ReWear, which uses the old suits as material for rugs.

Trunks run between $68 and $72.

Sometimes, secondhand shops are loaded with brand spanking new bathing suits. I'm talking swimsuits that still have the original tags and the crotch sticker, people.

If you don't mind buying a bathing suit secondhand, the thrift store (as well as apps like Poshmark and Depop) not only helps save something from the waste stream, but will also save you money. But if you'd rather not take the risk, all of the brands above have great options worth investing in.
