16 Brands Like Sozy for Cozy & Sustainable Fashion
You found a brand that makes loungewear from sustainable fabrics, and now your regular cotton sweats feel like a downgrade. The problem is that Sozy can only fill so many spots in your closet. You want more options that feel just as soft, look just as good, and treat the planet with the same respect.
We put together 14 brands that share that same cozy-meets-conscious DNA. Every pick below uses organic, recycled, or responsibly sourced materials and delivers the kind of relaxed fits you actually want to live in. A few notes: Sozy runs on Shopify, so their link may occasionally return a 405 depending on geo-restrictions. If it does, try again or search them directly.
Girlfriend Collective
Your favorite leggings are pilling after six months, and you keep buying replacements that end up in a landfill. Girlfriend Collective makes activewear and loungewear from recycled water bottles and fishing nets, so every pair of joggers or sweatshirts pulls waste out of the environment instead of adding to it. Their sizing runs from XXS to 6XL, and the color range goes well beyond basic black.
The vibe leans more athletic than Sozy, but the commitment to comfort and durability is the same. If you want pieces that move from a morning workout to an afternoon on the couch without a wardrobe change, this is your brand.
Best for: inclusive sizing and recycled activewear basics.
Tentree
Fast fashion brands promise affordability but cost the earth in water, chemicals, and landfill waste. Tentree flips that by planting ten trees for every item sold and building their collection from hemp, organic cotton, and Tencel. Their sweatshirts, tees, and joggers have a rugged outdoor feel that works whether you are hiking a trail or running errands.
The fits run relaxed and a little boxy compared to Sozy's more tailored loungewear, which makes them ideal for layering. You get comfort with a measurable environmental impact tracked through a unique token on every product.
Best for: outdoor-inspired basics with a verified tree-planting mission.
Everlane
Markup in fashion is wild, and most brands hide the real cost of production behind aspirational branding. Everlane breaks down the factory cost, materials, and margin on every product page so you know exactly what you are paying for. Their sweaters, relaxed pants, and layering basics are built from ethically sourced fabrics designed to outlast trends.
The aesthetic is cleaner and more structured than Sozy's lounge-first approach, but the quality of the cotton and cashmere feels comparable. Think of Everlane as the brand that takes your cozy wardrobe out of the house and into the office.
Best for: transparent pricing and minimalist everyday staples.
Reformation
Sustainable fashion has a reputation for looking plain, and that keeps a lot of people from making the switch. Reformation proves that eco-friendly clothes can also be genuinely stylish. They use deadstock fabric, Tencel, and organic cotton to create dresses, tops, and lounge sets that follow current trends without the environmental guilt.
Where Sozy keeps things relaxed and understated, Reformation adds more shape and feminine detail. If you want date-night pieces made with the same planet-first values as your favorite loungewear, this is the move.
Best for: trend-forward sustainable dresses and going-out pieces.
Pact
Organic cotton basics should not cost a premium that puts them out of reach. Pact keeps prices accessible while using Fair Trade Certified factories and GOTS-certified organic cotton across their entire range. Their loungewear, pajamas, and underwear feel soft from the first wear without the chemical softeners conventional brands rely on.
The designs are straightforward rather than fashion-forward, which makes Pact a strong foundation layer for any sustainable closet. If Sozy is your weekend brand, Pact is the everyday underwear-and-basics layer underneath it all.
Best for: affordable organic cotton basics and Fair Trade underwear.
Kotn
Most cotton labeled "Egyptian cotton" is not actually from Egypt, and the mislabeling problem is widespread. Kotn works directly with farming communities in the Nile Delta to source authentic Egyptian cotton and pays fair wages at every stage. The result is tees, sweaters, and joggers with a density and softness that cheaper cotton cannot match.
The look is more refined than Sozy's casual loungewear, landing somewhere between relaxed and polished. You can wear a Kotn crewneck to brunch or a meeting and feel appropriately dressed for both.
Best for: premium Egyptian cotton basics with direct farmer partnerships.
Nudie Jeans
Denim is one of the most resource-intensive fabrics to produce, and most pairs end up in a landfill within a few years. Nudie Jeans fights that cycle with free lifetime repairs, a buy-back program for used pairs, and organic cotton across their entire line. Their casual tees and sweatshirts carry the same ethical standards as their jeans.
While Sozy focuses on lounge pieces, Nudie fills the denim-shaped gap in a sustainable wardrobe. Pair their jeans with a Sozy hoodie, and you have a full outfit that respects both your comfort and the environment.
Best for: sustainable denim with free lifetime repairs.
Thought
Finding sustainable fashion that does not look corporate or clinical can feel like a challenge. Thought, a UK-based label, uses hemp, bamboo, and organic cotton to create pieces with a warm, bohemian character. Their joggers, oversized knits, and relaxed dresses come in earthy tones and natural textures that feel lived-in from day one.
The overall mood is close to Sozy's cozy ethos but with more pattern and personality. If you gravitate toward muted florals and textured knits over solid-color basics, Thought is worth exploring.
Best for: bohemian-leaning sustainable knitwear and earthy palettes.
Organic Basics
Basics should last longer than a single season, but most fast-fashion tees and leggings fall apart after a handful of washes. Organic Basics builds durability into every piece using organic cotton, recycled nylon, and Tencel. Their SilverTech line even uses recycled silver fibers for odor resistance, which means fewer washes and less water waste over time.
The design philosophy is stripped-back and functional, more Scandinavian minimalism than Sozy's relaxed California feel. But if you want underwear, leggings, and layering tees that genuinely hold up, this brand delivers.
Best for: long-lasting Scandinavian-style basics and odor-resistant activewear.
MATE the Label
Chemical dyes and synthetic finishes are standard in most clothing, and they sit against your skin all day. MATE the Label uses GOTS-certified organic cotton and natural dyes to create loungewear that is genuinely clean from fiber to finish. Their joggers, crewnecks, and bodysuits come in a muted earthy palette that mixes and matches without effort.
This is one of the closest alternatives to Sozy in both aesthetic and values. The relaxed fits, soft hand-feel, and commitment to non-toxic production make MATE a natural next step if you already love what Sozy offers.
Best for: non-toxic, naturally dyed organic loungewear.
Alo Yoga
Performance fabrics and sustainability rarely show up in the same sentence, especially in the yoga and athleisure space. Alo Yoga has started addressing that gap with pieces made from recycled and eco-conscious materials alongside their mainline collection. The brand is known for buttery-soft leggings and hoodies that transition from studio to street.
Alo runs more athletic and polished than Sozy's lounge-first approach, and the price point is higher. But if you want sustainable athleisure that performs during a workout and still feels cozy afterward, their eco-focused pieces are worth a look.
Best for: premium athleisure with sustainable material options.
Naadam
Cashmere has a reputation for luxury pricing and questionable sourcing, with overgrazing in Mongolia causing real environmental damage. Naadam works directly with herding cooperatives to source cashmere responsibly while paying fair wages. Their sweaters, joggers, and lounge sets are some of the softest pieces you will find anywhere.
The price sits above Sozy, but the warmth-to-weight ratio of quality cashmere is hard to beat when temperatures drop. If you want to upgrade your cozy rotation with a few investment-grade knits, Naadam is the brand to watch.
Best for: ethically sourced cashmere loungewear and cold-weather knits.
Frank And Oak
Building a full sustainable wardrobe gets expensive when every brand only covers one category. Frank And Oak offers a wide range of staples for both men and women, from sweaters and joggers to outerwear and accessories, all made with recycled or organic materials. Their circular denim program takes back old jeans for recycling.
The style is more polished and versatile than Sozy's lounge focus, making Frank And Oak a strong option for workdays and weekends alike. If you want one sustainable brand that can cover most of your wardrobe, this is a solid pick.
Best for: full-wardrobe sustainable staples for men and women.
prAna
Yoga pants and hiking gear often rely on virgin synthetics that take centuries to decompose. prAna builds their activewear and casual pieces from recycled polyester, organic cotton, and hemp while maintaining Fair Trade Certified production. The collection spans yoga, climbing, and everyday wear with a focus on functional comfort.
The brand skews more active than Sozy, but the relaxed fits and soft fabrics overlap in all the right places. If your version of cozy includes morning stretches or weekend trail walks, prAna bridges the gap between performance and laid-back style.
Best for: Fair Trade activewear built for yoga and outdoor movement.
