It’s official: winter is here, so you may want to get your outerwear in order. If you’re looking to add one winter jacket to your wardrobe this season, a puffer coat makes a great choice. 

Usually, puffers lean more towards the practical end of the spectrum and wool coats, trenches, and capes are more what we think of when we think of stylish, layered winter outerwear. But puffers have gotten a luxe makeover and the list of responsibly made puffer jackets continues to grow.

Gone are the days when we would only reach for these warm puffer jackets and parkas only out of necessity –think outdoor sports or extremely frosty days. They are a fixture of many coveted closets of IT girls and celebs alike. So, it really is the best time to invest in an ethical jacket that is super cozy too!

Below, 21 puffer coats from 7 No Kill-approved brands, who create clothes with minimized environmental impact and great ethical practices. From knee-length to cropped, matte neutrals to rich saturated colors and interesting finishes, there is a puffer coat for everyone.
