Everyone who lives in temperate climates needs protection in the winter to stay safe and enjoy the season. If your current cold weather wear is worn out or you’re looking for a great gift, you can’t go wrong with these durable and sustainable layers. The brands below offer a great range of parkas, vests, and lined hooded jackets. 

Here is our criteria for ethical and warm winter coats:

Ethical Insulation:  The insulation or lining in your winter coat is critical to keeping you warm. If your local climate includes heavy snow, wind, or rain, protection from the elements will be a major factor as well. The puffer coats and parkas on this list are filled with recycled synthetics, deadstock fabrics, or bio-based materials that will retain heat even in freezing temperatures. Many brands choose these insulators in place of feather down because in some cases, harvesting down feathers can be cruel (though that’s not necessarily always the case.) 

Eco-Friendly Exterior: For a weather-resistant shell, look for brands that use recycled synthetics for the outer layer. Many outdoor brands also add a durable water repellent to these performance jackets, be aware that it can be with toxic perfluorinated chemistry. If precipitation and heavy winds aren’t a concern, you can avoid synthetics and chemical finishes altogether and look for natural fibers such as organic cotton and wool. 

Longevity & Care: A good winter coat is an investment. It should be sturdy, durable, and last for many years to come. Be sure to properly care for your winter wear by carefully reading the maintenance instructions. For simple care, look for coats made of merino wool, which is naturally odor-resistant. 

Fair Labor and Sustainability: Look for brands that are directly involved in or transparent about their supply chains. Some brands own and operate their own factories, while others foster close long-term relationships with the manufacturers in their supply chains. To ensure labor and environmental responsibility, look for third-party certifications such as B Corp, Fair Labor Association, and Cradle to Cradle
