10 Best Sustainable Winter Coats For Ethical Winter Warmth

Staying warm during winter is essential. However, all those layers can come at a cost to the planet. Many of our coats and jackets come in materials made of animal hides, while other winter coats are made from synthetic fibers like nylon and polyester. The latter are essentially plastic fibers made from plastics that do not biodegrade and end up harming our environment. 

Thankfully, you can switch to sustainable winter coats made of eco-friendly materials and stay warm during the chilly season without harming the planet. Read on as we go through our handpicked selection of some of the best sustainable winter coats you can shop for today.

Did you know that 35% of primary microplastics released globally into the ocean come from synthetic clothing alone?1

The fashion industry makes most of the winter coats it churns out each season from synthetic fabrics like polyester, fleece, and nylon, which may work best at trapping heat but harm our environment. 

When we wash these winter coats, microplastics reach our waterways and oceans. When these microplastics end up in our oceans, they are ingested by aquatic animals, leading to alterations in their feeding behavior, damage to their reproductive rates, and even death. 

Sadly, reports say that the ratio of plastic to fish was 1:5 in 2014. That is one plastic bottle for every five fish. Switching to more sustainable fabrics can help reduce resource consumption and plastic waste, protect our aquatic animals, and save our planet. 

What to look for in sustainable winter coats 

In addition to the damage that synthetic materials cause our environment, many fast fashion manufacturers use unethical and unsustainable practices to make their coveted lines of winter coats. 

When shopping for sustainable winter coats, it is important to take a holistic view and consider the type of materials used, animal welfare, sourcing and manufacturing practices, and corporate responsibility. Here are a few things to consider when shopping for sustainable winter coats: 

Sustainable materials 

Winter coats typically have three layers: the outer shell, inside fill, and inner lining. All three layers help protect you from external factors like the wind while trapping heat.

While synthetics are excellent at protecting you from the cold, they do not protect our planet. In fact, plastics used in making these synthetics significantly contribute to microplastic pollution and global warming. 

When shopping for sustainable and ethical winter coats, look for eco-friendly, less environmentally harmful fabrics. 

You can choose recycled materials like recycled polyester, cotton wool, nylon, etc. You can also go for other natural fabrics like organic cotton, hemp, lyocell, etc. 

In addition, check out our guide to how to shop sustainably for more info on the fabric certifications to look out for. These include GOTS-certified, Bluesign®, OEKO-Tex, Global Recycle Standard (GRS), Responsible Down Standard (RDS), Responsible Wool Standard (RWS), etc.     

Ethical labor and production practices 

When picking out your next winter coat, choose to buy from sustainable clothing brands that reflect ethical and sustainable practices and fair labor. 

In other words, you want to look out for winter coats that are ethically sourced. Do they uphold high labor and production standards throughout their supply chain? 

You can look out for certifications like a Certified B Corp, Fair Trade (Fair Wear Foundation, Fair Labor Association, etc.).   

Sustainable business practices  

Besides ethically sourced sustainable materials, brands taking steps to reduce their environmental impact also make our list. The use of renewable energy throughout their supply chain, plastic-free packaging, carbon offset programs, and so on all help set them up as worthy of the sustainable label.
