15 Sustainable Swimwear Brands Ranked For 2024

1. Summersalt

Sustainable Materials | Recycled polyamide
Price Range | Separates starting at $45, one-pieces starting at $95
Size Range | XS–2X

Using 1.5M measurements from 10,000 women and a patented process, Summersalt makes the perfect fit when it comes to sustainable swimwear. Made with recycled textiles that boast five times the strength and four times the compression of other swimwear, these two- and one-piece suits (including maternity and long torso options!) are fashionable, sustainable, and made-to-last. Ethics is also at the forefront of production at Summersalt, with WRAP & BSCI certified production practices. Oh, and they’re affordable, too — most less than $100. We especially love Summersalt’s unique one-pieces — they provide comfortable coverage and fit while still feeling sexy.

Summersalt Review | “Mom of 2 here. I really wanted to make a bikini work for me but couldn’t find one that looked cute and felt comfortable. Enter this fabulous number, with an adorable print and sassy flutter sleeves. It fits so well, I honestly feel like a million bucks wearing it. Secure enough when chasing around said children. Top designed well for nursing baby.  Thank you Summersalt!! I’ve never felt so confident in a swimsuit! – Katharine K. (See all reviews)

2. Patagonia

Sustainable Materials | Recycled nylon, recycled polyester
Price Range | Separates starting at $65, one-pieces starting at $139
Size Range | XXS–XXL

Patagonia’s passion is equal-parts activewear and ethics, so you can expect high-performance bikinis, rashguards, one-pieces, and boardshorts that are stretchy, secure, and sustainably made from fair trade recycled fabrics. Since 1985, Patagonia has pledged one percent of its sales to the preservation and restoration of the environment, so you can feel good about your purchase — whether you’re planning to catch waves or ZZZs on the beach.

Patagonia Review | “This is the best bikini bottom I’ve ever worn to surf. It’s comfy and stays in place in all kinds of waves and white water. I have this same bottom in nearly 10 different patterns, it’s currently the only swimsuit bottom I wear to surf.” – Allison (See all reviews)

3. Vitamin A

Sustainable Materials | Recycled nylon
Price Range | Separates starting at $150, one-pieces starting at $235
Size Range | XS–XXL

Founded, designed, and produced in California, Vitamin A swimwear is inspired by ‘70s beach glamour. The brand is leading the way with fabrics like EcoLux™, a superfine matte jersey, as well as stretch-ribbed EcoRib®, both of which are made from recycled nylon and plant-based fibers. The prints are created, when possible, with water-reducing digital technology and the packaging boxes are fully recyclable and biodegradable. There are hundreds of options to choose from — and each one is as eye-catching as the next. Our editors have personally tried Vitamin A swimwear and can attest to the flattering fit, quality fabrics, and playful prints that leave us wanting summer to last year-round!

Vitamin A Review | “I just live this bathing suit. Finally I found one that I truly love and fits awesome. I’m 5’2 at 120lbs. Bought a medium.” – Shelly (See all reviews)

Best For | Gender-neutral & gender-fluid swimwearSustainable Materials | Recycled polyester, OEKO-TEX certified materials
Price Range | Separates starting at $49, unisuits starting at $89
Size Range | XS–6X

Don’t let the name fool you, TomboyX was created for “any girl or woman or person” who dresses and expresses themselves the way they please. If you’re looking to break from the itty-bitty bikini mold, the certified B Corp makes gender-neutral tanks, halter tops, and racerbacks that can be paired with shorts of varying lengths — or you can opt for a unisuit altogether. All are quick-drying, equipped with UPF sun protection, and made with OEKO-TEX certified fabrics. (And the brand’s ethics and sustainability are top-notch, too.)

TomboyX Review | “I bought a size up after looking at reviews. It fits perfectly. I was worried the length would be too short bc I sensitive about my thighs and didn’t want them to rub, but the length is perfect. It doesn’t give you an extra long crotch either, it goes where you need it. The zipper tucks away as well so you don’t have it swinging around or feel that it’s going to get stuck on something. The sleeves are nice and form fitted too. 10/10 would recommend.” – Melanie T. (See all reviews)

5. Londre

Sustainable Materials | Recycled plastic bottles
Price Range | Separates starting at $123, one-pieces starting at $205
Size Range | XS–5XL

Londre was born when its co-founders became obsessed with creating the highest quality bodywear with the lowest impact. Now, the brand’s best-selling one-pieces can be worn to the beach as easily as they can be paired with a blazer. But if you’re looking for something more classic (with a twist!), opt for the high-waisted bottoms and asymmetrical tops. We’ve never worn a suit quite like one from Londre — the cut and shape are so unique and we get lots of compliments on these pieces. Made in bright colors and patterns, the products are able to withstand all salt, sand, or sweat.

Londre Review | “This suit fits like a glove. Shows off my curves and is cut in such a way that you have coverage where needed and a little pop of skin that showcases my assets beautifully. The fiesta red is RED HOT ” – Sarah P. (See all reviews)

Made from EVO, a biobased polyamide made from renewable plants (that’s fully plastic-free!) and recycled nylon, each swimwear piece is stretchy and has a soft cotton-like feel for ultimate comfort. Our favourite styles are the Joy One Piece Swimsuit for its sporty retro vibe, and the Nile Bikini Top and matching Faro Bikini Bottoms for an easy-going casual beach day.

Sustainable Materials | Recycled polyamide, recycled polyester
Price Range | Separates starting at $42, one-pieces starting at $120

(By 2025, 100 percent of its swimwear textiles will be recycled!) You won’t need to replace your bikini after only one season either; the team promises its suits will last. The 365-day return policy (for exchange or credit) guarantees it. Boden ships globally!

9. Youswim

Sustainable Materials | OEKO-TEX certified nylon & elastane
Price Range | $149
Size Range | US 2–14, UK/AUS 6–18

Seven sizes in one? We know, but hear us out! Youswim simply doesn’t do sizes; the brand has four uniquely simple styles instead — the Aplomb, Eva, Poise, and Verve. Find the fit you love most, choose one of the vibrant colors, and pay one price across all pieces. Each sustainable swimsuit is made with European-sourced nylon, woven ethically in England and is certified Plastic Negative; the team is also diligently working on a recycled nylon fabric to use instead to maximize its sustainability.

YouSwim Review | “After a year of contemplating buying a suit from Youswim I finally pulled the trigger. A great investment and will be purchasing another. Form right to your body. Is flexible, comfortable and great material.” – Michalena R. (See all reviews)

10. Jessica Rey Swimwear

Sustainable Materials | 100% regenerated EcoLux fabrics
Price Range | Separates starting at $77, one-pieces starting at $182

Jessica Rey Swimwear designs swimsuits that are both modest and playful. Using luxe Italian fabrics, made from regenerated polyamide (sourced from rescued fish nets), the designs are then cut and sewn in Los Angeles. Paying living wages in sweatshop-free factories, Jessica Rey is not only dedicated to ethical production and sourcing practices but to respecting its makers as much as it does the consumers. We love this brand’s diverse swimwear options, like tankinis, mommy-and-me sets, and swim dresses!

Jessica Rey Review | I am quite different sizes between bust and hips but this suit is super flattering and fits well in all places. I used the chat feature for size recommendations and they used my bra size. Excellent colors and look and could not ask for better customer service!! Highly recommend getting your next suit or summer outfit here. – Erin W. (See all reviews)

11. Cosabella

Sustainable Materials | Polyamide
Price Range | Separates starting at $110, one-pieces starting at $235
Size Range | XS–XL

Cosabella has spent the last 40 years perfecting Italian lingerie — and now its collection includes stunning swimwear as well. Using recycled nylons and elastane, the Vita Marina line includes bandeaus, shirred bottoms, and one-pieces in three basic (but naturally rich!) colors. The bandeaus in particular can be worn a number of ways, wrapped around the neck for extra support or tied into a front knot. Sizes go up to 40H for cups and 43.5” for bottoms.

Cosabella Review | “I was so excited to buy this swimsuit as Cosabella fits me so well. This suit did not disappoint! It’s perfect! And so flattering. I’m going to purchase the red one as well.” – Janene W. (See all reviews)

12. ALOHAS

Sustainable Materials | Ecoyarn polyester
Price Range | Separates starting at €45; one-pieces starting at €100
Size Range | XS–XXL

ALOHAS believes that swimwear should be chic, comfortable, and sustainable. Their gorgeous swimwear line is eco-friendly and ethical, produced on-demand in Spain from quality materials that won’t harm the environment or our bodies. Their production model helps eliminate overstock and waste, so they only make garments that have been ordered. The team practices fair labor practices with their factories in Spain and Portugal, and all their products are cruelty-free.

Alohas Review | “Absolutely perfect bathing suit, hugs in all the right ways but doesn’t wedgie or restrict, a very elegant cut. Color is gorgeous, new favorite I look forward to wearing for many years.” – Grace F. (See all reviews)

13. Wolven

Sustainable Materials | Recycled PET
Price Range | Separates starting at $72, one-pieces starting at $154
Size Range | XS–XL

Wolven’s founder Kiran Jade draws from her South Asian family’s background for its gorgeous patterns and textiles. Wolven’s swimwear for example — made up of one-pieces and bikini sets — includes mandalas and henna-inspired designs. Each piece is made from 80+ percent recycled plastic bottles with a bit of spandex for extra stretch, so you can run freely across the shores or cannonball into the pool. The fact that many of Wolven’s suits are reversible is so fun to experiment with. (But heads up: If you need structured support, cups, or additional lining, this might not be the brand for you!) Wolven orders are carbon-neutral, give back to environmental causes, and are sent in either recycled or biodegradable packaging.

Wolven Review | “The shape is so so good! They are *actually* high waisted (go up to your waistline) which is SO hard to find. If you hate classic low-rise bikini bottoms, I would highly recommend these for a more flattering fit! They have soft seams too so they don’t make your hip fat bulge out like other bathing suits. They’re just the right amount of cheeky. Great option for people who struggle with awkward bikini bulges!” – Allison W. (See all reviews)

14. BOLD Swim

Sustainable Materials | Recycled polyamide 
Price Range | Separates starting at $65, one-pieces starting at $125
Size Range | S–XXL

BOLD Swim is precisely what it sounds like: swimwear for the bold, unafraid, and unapologetic woman. With luxury eco-nylon sourced from Brazil, these swimsuits are nontoxic, biodegradable, and UV protected. Moreover, this BIPOC-owned brand is carbon neutral and crafts exceptionally colorful and cute designs, with sizes up to XXL. Heads will turn whether you’re rocking a cut-out one-piece or a pastel bikini.

BOLD Swim Review | “I love this one piece. It is the softest swimwear I’ve ever encountered and the cut is perfect!” – Rhiannon M. (See all reviews)

15. Galamaar

Sustainable Materials | Recycled ECONYL®
Price Range | Separates starting at $118, one-pieces starting at $248
Size Range | XS–XL

At Galamaar, waste-to-wear is the name of the game. These beautiful suits are made in part using recycled Econyl®, a fabric derived of nylon from trashed fishing nets that account for nearly 10% of ocean pollution. Not only is the material sustainable, but it’s also made to last: following the brand’s care guidelines, your Galamaar suits can last a lifetime. Made in a small, family-owned and operated fair-wage manufacturer in LA, you can feel good about this swimwear that is ethically made, eco-friendly, and extremely chic.

Galamaar Review | “These bottoms are cute, trendy, and offer moderate coverage! I have a pear shape and generally head towards hipster/banded bikini bottoms. I wanted something a little bit more fashion-forward and this was exactly what I was hoping for! I have a short torso, 5’8″ approx 144 pounds (bottom heavy/athletic legs). I ordered a size medium and ordered the matching neeve bikini top. With these bottoms, I can move around and not worry about coverage. 4 stars because there’s no band at all, cutting into the tummy a bit (though it doesn’t look bad!).” – Alleeona (See all reviews)
