12 Sustainable Recycled Swimwear Brands Making Better Bikinis
Can a recycled swimsuit really be more sustainable?
Swimwear is usually made from synthetic fibers, so the better question is not whether a suit is perfect—it is whether a brand is transparent about its materials, production, and durability.
These 12 brands use recycled nylon or polyester in at least part of their current swim collections. I checked the claims against current brand and product pages, but fabric content can vary by style. Always open the product details before buying.
My rule: choose a suit you will genuinely wear for years, rinse it after salt or chlorine, and skip vague “eco” claims that do not name the fabric. Building the rest of your dive kit? See my guide to the best scuba masks for women.
A better swimsuit starts with better questions
What percentage is recycled?
Which certification supports the claim?
Will the cut and quality keep this suit in your rotation for years?

Salt Gypsy

BERLOOK
Based in: USA
