If you live in a location where winter exists, you know that a good coat is an investment you just have to make. Unless you want to end up freezing and seriously regretting your decision every time you go outside, it’s not something you can or should buy cheap. It might cost you a bit more up front, but if you choose wisely, purchasing a sustainable, high-quality winter coat can last you a really long time. I would even say it’s a key to happiness in cold weather!

Here’s what to look for:

The Outer Layer

In order to make them waterproof, many coats are made out of synthetic materials like polyester or nylon, which are essentially plastic, and harmful for 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. All of the brands below either use natural, biodegradable fibers or recycled synthetic fabrics.

The 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.

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 (whenever we’re allowed to do that again).
