16 Brands Like Two Thirds for Sustainable Fashion
You want clothes that look good and do good, but finding brands that genuinely care about the ocean is harder than it should be. Fast fashion is drowning our seas in microplastics and waste, and greenwashing makes it tough to tell who is actually walking the walk. Two Thirds set the bar with their Barcelona-born, ocean-first approach to sustainable style.
We love Two Thirds for their commitment to protecting marine ecosystems through responsible fabrics and transparent production. If you share that passion for the coast and want more options in your rotation, these 13 brands bring the same ocean-conscious energy to your wardrobe.
Outerknown
Your wardrobe is full of pieces that fell apart after a season, and you are tired of replacing basics that cannot handle real life. Co-founded by surfer Kelly Slater, Outerknown builds rugged coastal staples from recycled and regenerated materials like ECONYL nylon pulled from ocean waste. Their Blanket Shirts and sun-washed flannels are designed to last for years.
The brand partners with Fair Trade certified factories and measures its environmental impact across every product. If you want that salt-aired, lived-in look backed by genuine accountability, Outerknown delivers.
Best for: Laid-back coastal staples built to last.
Finisterre
Cold-water surf gear often means choosing between performance and sustainability. Finisterre refuses that trade-off. Born on the rugged Cornish coast, they make wetsuits, waterproof jackets, and layering pieces from recycled and natural materials designed for life in and around the ocean.
Their commitment runs deep. Finisterre developed one of the first recycled wetsuits on the market and runs a repair program to extend the life of every piece. For anyone who spends time in cold water and wants gear that respects the environment it was made for, this brand is hard to beat.
Best for: Cold-water adventurers who demand functional, ocean-friendly gear.
Patagonia
Most outdoor brands talk about the environment, but few have restructured their entire company around saving it. Patagonia made headlines by transferring ownership to a trust dedicated to fighting climate change. Their jackets, fleeces, and wetsuits are built from recycled materials and backed by a lifetime repair guarantee.
Their ocean-specific work includes funding marine conservation projects and pioneering the use of recycled fishing nets in their clothing. The style leans functional rather than fashion-forward, but when you need outerwear that performs on a windswept coastline, Patagonia has decades of proven credibility.
Best for: Durable outdoor layers from a brand that puts activism first.
Ecoalf
Plastic waste is choking the Mediterranean, and most fashion brands pretend it is someone else's problem. Madrid-based Ecoalf decided to turn that trash into clothing. Their "Upcycling the Oceans" project works with fishing communities across Spain to collect ocean plastic and transform it into yarn for jackets, sneakers, and everyday basics.
The result is a full lifestyle collection that looks modern and clean without any hint of "recycled" compromise. Ecoalf proves that waste can become genuinely desirable clothing, and their partnership with fishing fleets gives the ocean conservation angle real weight.
Best for: Modern European style made from recovered ocean waste.
Waterlust
Most activewear brands slap a wave graphic on a tank top and call it "ocean-inspired." Waterlust is different. Founded by marine scientists, every piece features original designs based on real oceanographic data, and a portion of profits funds specific marine research projects.
Their leggings, rash guards, and swimwear are made from recycled plastic bottles, and every product tag tells you exactly which research initiative your purchase supports. If you want activewear with genuine scientific credibility behind its ocean mission, Waterlust is the real deal.
Best for: Science-backed activewear that directly funds marine research.
Seea
Finding surf and swim pieces that actually stay put in the water while looking good on land feels impossible. Seea was built specifically for women who surf, swim, and spend their days near the coast. Their retro-inspired swimsuits, rash guards, and surf suits use recycled fabrics and are designed to perform in real waves.
Based in Southern California, Seea keeps production close and transparent. They focus on small, intentional collections rather than constant drops, which keeps waste low and quality high. For women who want functional surf style with a vintage edge, Seea fills a gap no one else does.
Best for: Women who surf and want retro-inspired, performance swimwear.
Vissla
Surf culture has a disposable clothing problem, and Vissla is trying to change that from the inside. Their Upcycle collection turns coconut husks, recycled plastic bottles, and organic cotton into boardshorts, tees, and wetsuits that hold up season after season.
Vissla works with the Surfrider Foundation and other ocean conservation groups, giving their sustainability claims some real teeth. The aesthetic is classic California surf with a creative edge. If you are looking for boardshorts and casual pieces that respect the lineup and the coastline, Vissla brings credibility to the category.
Best for: Surf-rooted guys who want eco-conscious boardshorts and casual wear.
United By Blue
Every brand says they care about clean oceans, but few literally show up with trash bags. United By Blue removes one pound of trash from oceans and waterways for every product sold, and they have organized hundreds of community cleanups since launching.
Their clothing line covers everyday basics, outerwear, and accessories made from organic and recycled materials. The style sits somewhere between outdoor brand and casual weekend wear. For anyone who wants their purchase to trigger direct, measurable cleanup action, United By Blue makes that connection tangible.
Best for: Everyday basics backed by direct waterway cleanup efforts.
Batoko
Budget-friendly sustainable swimwear barely exists, and most affordable options rely on virgin synthetics that shed microplastics with every wash. UK-based Batoko makes bold, colorful swimsuits entirely from recycled plastic waste, proving that fun prints and environmental responsibility can share the same rack.
Their range covers one-pieces and bikinis in playful patterns, all produced in a small Italian factory focused on low-waste manufacturing. Batoko keeps things simple and accessible, which makes them a strong entry point for anyone building a more responsible swimwear drawer without a designer price tag.
Best for: Affordable, fun swimwear made from recycled plastic.
Pangaia
Loungewear and basics brands rarely push the envelope on materials science, which means you end up with the same organic cotton hoodie from a dozen different labels. Pangaia takes a different approach, developing fabrics from seaweed fiber, recycled cotton, and bio-based dyes sourced from food waste.
Their signature hoodies and track pants come treated with peppermint oil for natural freshness, and the brand invests heavily in textile innovation research. The price point sits higher than fast fashion, but you are paying for genuine material breakthroughs rather than marketing. For ocean-lovers who want cutting-edge sustainable basics, Pangaia is pushing the industry forward.
Best for: Material science enthusiasts who want innovative, planet-first basics.
Faherty
Coastal style often gets reduced to generic beachwear that looks out of place anywhere beyond the boardwalk. Faherty builds a full wardrobe around that sun-faded, shore-town feeling without sacrificing polish. Their button-downs, knit blazers, and signature Legend tees work as easily at a summer dinner as they do on a morning walk along the coast.
The brand uses organic, recycled, and regenerative materials across their collections, and their Faherty brand foundation supports environmental and community causes. If you want that effortless coastal American look grounded in responsible sourcing, Faherty bridges the gap between beach and real life.
Best for: Polished coastal style that works beyond the beach.
Girlfriend Collective
Activewear generates enormous amounts of synthetic waste, and most workout leggings are made from virgin petroleum-based fabrics. Girlfriend Collective flipped that model by building their entire line from recycled materials, including post-consumer plastic bottles and discarded fishing nets pulled from the ocean.
Their leggings, sports bras, and loungewear come in an inclusive size range and a rotating palette of colors. Production happens in certified factories with verified fair wages. For anyone who wants workout gear that tackles ocean plastic pollution head-on, Girlfriend Collective backs up their claims with full supply chain transparency.
Best for: Inclusive activewear made from recycled ocean and landfill waste.
Reformation
Trendy clothes and environmental responsibility usually sit on opposite ends of the spectrum. Reformation built their reputation by making fashion-forward dresses, denim, and tops from sustainable fabrics like Tencel and deadstock material, all while tracking the environmental footprint of every single product on their site.
Their RefScale tool shows the pounds of CO2 saved and gallons of water conserved for each item compared to conventional production. The aesthetic leans feminine and Los Angeles cool, which is a shift from Two Thirds' minimalism, but the commitment to measurable impact is equally strong. For statement pieces that come with hard data on their environmental savings, Reformation sets the standard.
Best for: Trend-driven pieces with transparent environmental impact data.
