The Best Sustainable & Eco Swimwear Brands
By The Swim Edit · June 2026
There is a quiet revolution happening on the world's most beautiful beaches, and it has nothing to do with cut or colour. The swimwear that turns heads this season is the kind made from reclaimed fishing nets and regenerated nylon — proof, at last, that doing right by the ocean and looking exquisite beside it are no longer mutually exclusive. Consider this your considered guide to the eco-conscious labels worth packing.
Vitamin A: California's Original Eco Pioneer
Long before sustainability became a marketing buzzword, Vitamin A was quietly cutting its sun-warmed silhouettes from EcoLux — a recycled nylon spun from discarded fishing nets and post-industrial waste. The result is the kind of swimwear that feels like a second skin: ribbed maillots, scooped-back one-pieces and the sort of high-leg bottoms that flatter every figure. If you buy one eco suit this year, make it from here.
Hunza G: One Size, Infinitely Worn
There is a particular genius to Hunza G and its crinkle-stretch fabric, which moulds to the body with such forgiveness that the brand sells most styles in a single size. Sustainability, here, is partly a matter of longevity: a Hunza G suit is bought once and worn for a decade, its nostalgic seersucker texture as good in year ten as on day one. The brand has steadily moved toward recycled nylon, too, making the classic square-neck swimsuit a genuinely guilt-free indulgence.
Bondi Born: Australian Craft, Built to Last
Few brands marry environmental rigour with sheer elegance as gracefully as Bondi Born. Its sculptural one-pieces are cut from EcoLux and Italian regenerated yarns, designed and ethically produced in small runs to avoid the waste of overproduction. The aesthetic is grown-up and architectural — clean lines, considered seaming, the occasional sharp shoulder — for the woman who wants her swimwear to look as though it were chosen, not merely bought.
L*Space: Effortless California, Recycled Roots
For those who like their swimwear with a little more sun-soaked ease, L*Space offers ribbed bikinis and reversible bottoms made increasingly from recycled fabrics, all designed and sewn in California. The palette leans into terracotta, sand and seafoam — colours that look as natural against a sandstone cliff as they do a hotel pool — and the fit is generous without ever sacrificing shape. A reliable choice for the holiday wardrobe you will actually re-wear.
Bond-Eye: The Cult Recycled One-Piece
If your social feeds have lately been awash with seamless, second-skin maillots in butter-soft ribbing, you have Bond-Eye to thank. The Australian label crafts almost its entire collection from REGENERATED — a recycled fabric reborn from ocean and landfill waste — without ever compromising on that signature buttery hand-feel. The Mara and Madison one-pieces, in particular, have achieved near-cult status, and deservedly so.
Frankies Bikinis: Conscious Glamour
Frankies Bikinis has built its reputation on the romantic — gingham, lace trims, the sort of triangle bikini that belongs on a Capri terrace — and has increasingly woven recycled and sustainable fabrics through its collections. For the reader who wants a little flirtation with her eco credentials, this is the label that delivers prettiness without the guilt. Pair a Frankies set with a linen shirt and you have a look that travels from sunbed to sundowner with ease.
A Note on Fit, Care & Styling
The single greatest act of sustainability is simply wearing a piece for longer — so buy well, then care well. Rinse swimwear in cool fresh water after every dip (sun cream and chlorine are far more punishing than the sea), lay flat to dry away from direct heat, and resist the wring. For shape, let your silhouette lead: a high-leg one-piece elongates, a square neck balances a fuller bust, and a ribbed texture quietly smooths. Build a small, beautiful rotation rather than a drawer of fast-fashion castoffs, and discover more of our favourites across the edit.
