A winning winter wardrobe is one that keeps us toasty without melting an ice cap, so we sifted through piles of jackets, coats, parkas and puffers to find the most sustainable outerwear brands that use low-impact materials, ethical labor, and transparent supply chains.

Why Choose Sustainably Made Jackets & Coats?

Buying secondhand is always the most sustainable choice but if you do need to buy new, here’s 3 good reasons to support a more sustainable brand:

  • Traditional jackets often use virgin synthetic materials that are made from fossil fuels which produce higher emissions and fuel demand for the plastic industry.
  • Jackets made by fast fashion brands are often made in factories with questionable labor practices.
  • Buying from a smaller brand who prioritizes sustainability casts a vote for the type of fashion industry you want to see.

We’ve hunted for brands that make their jackets and coats from more sustainable materials including recycled synthetics or natural materials. Brands on this list also take a much more conscious approach to caring for the people in their supply chains.

Our Brand Rating System now extends what we look for in brands (who opt in) to a wide range of 22 different sustainability related criteria, including things like circularity, climate action, biodiversity impact and more. Look out for rated brands on the list below and find others in our sustainable brand directory.

Outerknown

Outerknown has not been rated.

Price Range: $331—$555

A sustainable swimwear brand founded by the world’s most famous surfer, Kelly Slater, Outerknown now covers a lot of clothing bases.

When winter winds blow, they offer sustainable men’s sports coats, utility jackets, water-repellant wind shells, puffer jackets, and ultra-thick flannel shackets in the form of their best-selling Blanket Shirt.

OK’s lighter sustainable jackets for women aren’t meant for super frigid temperatures but are on-point for fringe seasons. These include shirt jackets, denim jackets, and “shirt-jackets”.

Fabrics include recycled materials (polyester, nylon, polyamide cotton, and wool), TENCEL™ Lyocell, regular wool, cupro, and RDS-certified down. Only a few contain virgin polyester or minimal spandex.

If you want organic coats, they have several made of 100% organic cotton or a hemp and cotton blend. Any water-repellency is thanks to a PFOA-free DWR coating.

Outerwear uses Fair Trade-certified facilities across Peru, China, and Mexico and works collectively with workers to ensure they’re paid a premium for their work along with extra funding to improve their lives even more. All suppliers must also adhere to a Fair Labor Association Code of Conduct.

My Personal Review of Outerknown’s Blanket Shirt:

“I’m totally in love with The Blanket Shirt from Outerknown. Made of tightly woven, thick, 100% organic cotton with biodegradable corozo nut buttons, it’s a game changer. Who knew flannel could be this cozy? I’ve got three now because I literally wear them ALL the time.”

Patagonia

Patagonia has not been rated.

Price Range: $117—$649

This sustainable outdoor clothing brand needs no introduction. Patagonia has been equipping people for skiing, ice climbing, winter hiking, and extreme cold mountaineering for almost five decades—so suffice it to say they know their snow stuff. With ski jackets, GoreTex rain shells, insulated jackets, fleece jackets, and shackets, there’s something for everyone.

The materials used by Patagonia’s lighter ethical jackets include regenerative organic cotton, recycled or ethically sourced wool, recycled polyester, and organic cotton. For more burly outerwear, you’ll find mostly recycled synthetics, like nylon and polyester shells coated in PFC-free waterproof coatings.

Their insulation consists of 100% recycled P.U.R.E.™ (Produced Using Reduced Emissions) PrimaLoft® Gold or RDS-certified down in the down coats.

Fair Trade-certified sewing for most of their outdoor apparel along with numerous other sustainability related efforts have historically earned them top spots in Fashion Revolution’s Fashion Transparency Index.

They buy-back and resell old Patagonia garments through the Worn Wear program (a way to get major deals on like new stuff) and offer a lifetime of repairs via their IronClad guarantee.

They co-founded 1% For the Planet and recently sold the company to two environmental nonprofits—meaning all profits moving forward will help fight climate change.

My Personal Review of Patagonia’s Nano Puff® Hoody Pullover:

“Among the many Patagonia pieces I’ve accumulated over the years, the Nano Puff® Hoody is by far one of my favorites, no matter the time of year. This fully recycled synthetic puffer is warm, wind-resistant, and incredibly lightweight. It can be packed down into its own chest pocket, and the hood fits snugly under a cycling or climbing helmet—making it the ideal layer for everything from outdoor adventures to everyday wear.”

Reformation

Reformation has not been rated.

Price Range: $115—$1800

Reformation have a full line of women’s fashion items but we came for the coats. In addition to more stylish blazers, bomber, denim, and leather jackets, this fast fashion alternative brand has a full line of heavier sustainable winter coats in short to full-length designs.

Most of their sustainable outerwear consists of wool coats, featuring a blend of 70% recycled MWool®, 12% recycled polyamide, and 18% polyamide. Others contain recycled or regenerative cotton and/or deadstock materials (i.e. leftovers from manufacturing or unsold garments from other companies) polyester and wool.

They offer a handful of sustainable leather jackets featuring leather sourced from LWG-Gold or Silver rated tanneries.

Between their map of suppliers and factory list (though 33 of these are owned by Ref themselves and located right in LA), their Code of Conduct, and compliance with international standards for fair labor conditions, Ref is committed to an ethical supply chain.

While 65% of their garments are USA-made, the others in China, Morocco, and Turkey are Global Social Compliance Program compliant.

Reformation is carbon neutral and as part of their Circular Fashion System Commitment, RefRecycling encourages you to rewear, resell, or recycle via a partnership with SuperCircle.

Mila.Vert

When the temperature drops, Mila.Vert’s cardigan coats offer warmth without compromising on ethics or elegance.

This Slovenia-based slow fashion brand creates refined, minimalist outerwear designed to elevate any cold-weather look. Their timeless organic cotton coats—some featuring detachable belts or oversized lapels—are ideal for crisp fall mornings, sustainable work clothing for office commutes, and layered winter looks.

Each style is designed by founder Tina Logar Bauchmüller to be both functional and flattering, embodying the quiet luxury of European slow fashion.

Mila.Vert’s coats are crafted using 100% certified organic cotton, and dyed with natural, non-toxic dyes. Some styles may include other sustainable fibers like recycled wool or TENCEL™, sourced exclusively from ethical and eco-conscious partners.

Every garment is locally made in Slovenia by a trusted network of partners including Liniatex, Krona, eSPe sewing, and Jakopina. This close, transparent supply chain allows Mila.Vert to uphold fair labor standards and exceptional quality.

With a made-to-order production model, Mila.Vert only makes what’s needed—eliminating overproduction, cutting down textile waste, and lowering their environmental impact.

prAna

prAna has not been rated.

Price Range: $89—$470

At prAna, you’ll find technical garments in the form of wool coats, puffers, wind anoraks, rain jackets, and more casual corduroy coats, fleece jackets, and shirt jackets, like the classic Bridges Flannel Jacket.

The yoga clothing brand uses a mixture of low-impact fabrics (like recycled materials, recycled wool, hemp, TENCEL™ Lyocell, and organic cotton) along with some not-so-sustainable fabrics (like virgin polyester, lycra, and elastane). However, you can find some made of 100% recycled polyester or nylon.

Many are bluesign® approved and contain PFAS-free durable water repellent treatments. And they use RDS-certified down for their puffers.

prAna were one of the first North American apparel brands to produce Fair Trade-certified clothing. They work with several factories around the globe (mostly in Vietnam, India, or China) and ensure that they all meet strict standards when it comes to things like forced labor, child labor, harassment, hours of work, and health and safety.

Sustainable Jackets & Coats FAQ

1. What makes a jacket sustainable?
Sustainable jackets are typically made from sustainable fabrics like recycled polyester, organic cotton, or semi-synthetic fabric produced in a closed-loop system (e.g. TENCEL lyocell). Brands who make these more sustainable options prioritize ethical labor practices, often using Fair Trade-certified facilities, and find ways to reduce carbon emissions (they may even be carbon neutral).

2. Are ethically made jackets more expensive?
While some jackets on this list may have a higher upfront cost due to ethical manufacturing and quality materials, they often prove to be more cost-effective over time. They are designed to be durable and long-lasting, and typically with classic style in mind.

3. How do I know if a brand is truly sustainable?
It’s tricky. But checking for certifications like GOTS and Fair Trade help. Additionally brands who ensure their production facilities are audited by independent third parties are generally more conscious and caring about their ethics and supply chain. Brands should transparently share details about their materials, labor practices, and environmental impact. You can also check out our Brand Directory to find brands we’ve rated.

4. Can I recycle my old jacket?
Yes, many brands offer take-back programs to recycle old jackets. Some organizations also accept donations of gently-used winter coats for those in need. Otherwise, you can try repurposing it or selling it online.

5. What are the warmest sustainable jacket materials?
Recycled wool, recycled down, and synthetic insulation made from recycled polyester are some of the warmest options. These materials are designed to retain heat while being lightweight and breathable. Paka is a brand on this list that offers their own proprietary filling made with a mixture of alpaca and recycled polyester.

6. How can I take care of my sustainable jacket to make it last longer?
Great question, and one of the most important to ensure we keep our clothing in use longer. Follow care instructions provided by the brand, which usually involves hand washing or using machine settings, and drying naturally. Avoid using fabric softeners as they can affect water-resistant coatings. We also highly recommend taking your jacket to your local alterations service to repair any rips or tears.
