If you live in a location where winter exists, you know that a good coat is a necessary investment not to be taken lightly. Unless you want to end up freezing every time you go outside, it’s not something you can or should buy cheap. It might cost you a bit more upfront, but if you choose wisely, purchasing a sustainable, high-quality winter coat can bring you years and years of comfort and happiness.

Here’s what to look for in an ethical and sustainable winter coat:

An eco-friendly outer layer: All of the brands below either use natural, biodegradable fibers or recycled synthetic fabrics. Puffers are made out of synthetic materials like polyester or nylon, which are essentially plastic, and harmful to our environment. Of course, water resistance is really great—even a necessity—when it’s snowy outside, so look for recycled synthetics instead.

When water resistance isn’t needed, though, wool is usually the warmest of all of the natural fabrics. Just beware of synthetic wool-imitators such as acrylic, which is a fossil-fuel-based plastic fiber. 

Sustainable stuffing: What’s inside puffy winter coats is actually what keeps you the warmest. Whenever possible, you want to look for either recycled and/or ethically-sourced down filling. The down that geese and ducks produce is made to keep them super warm while they’re outside during the winter, and there isn’t a synthetic available that beats it when it comes to warmth. If you live in a super-cold climate, that’s key.

Non-toxic durable water repellent: Many outdoor brands use durable water repellant (DWR) based on a toxic class of chemicals called PFAS or PFCs. Called forever chemicals, they can slough off into toxic dust in your home and in the environment, and have been linked to cancer, infertility, thyroid issues and obesity. If you’re going for a snow coat or puffer, check to see if the brand is PFAS or PFC-free. More about this here.

The brands below are our favorite when it comes to ethical, sustainable winter coats for both men and women. They all prioritize transparency in their production and they all use mostly eco-friendly recycled and/or natural materials. You’ll find a wide variety of coats, from ultra-warm puffy coats that you can take skiing or camping, to sleek and classy wool coats that you can wear to the office or out on the town.
