20 Best Sustainable Swimwear Brands For Earth Loving Beach Bums & Adventurers [2024]
Here's our 2023 guide to our favorite eco swimwear brands you can browse through as you daydream about your upcoming beach days.
Conventional swimwear is made of virgin nylon and polyester. That's plastic, which will not biodegrade and requires us to keep drilling for more and more petroleum. As off-shore drilling projects increase, we'll just have less pristine oceans to enjoy.
Good thing we've already got lots of eco-conscious and sexy, elegant, and stylish swimwear to choose from.
While many of the following eco swimwear brands still use nylon and polyester, these plastic fibers are recycled from trashed fishnets and plastic bottles, meaning we're not increasing demand for new plastic and are helping to give new life and value to what otherwise would just be trash.
First make good use of all the bikinis and one-pieces you already have, treasure-hunt for pre-loved options from our favorite secondhand retailers, then dive in.
