Cozy sweaters are the cornerstone of any cool-weather wardrobe — make it a conscious choice with our curation of sustainable sweaters.
Most of the conventionally available sweaters are made from cheap acrylic fibers that not only give you the ghastly static cling but are actually made from non-biodegradable plastic. Since sweaters are those one-and-done investments you’ll hardly consider replacing for years to come, we suggest making them an eco-friendly natural and/or recylced fabric choice instead.
With this in mind, we’ve rounded up some fabulous—and totally snuggle-worthy—options to help you stay warm in some serious style. Ranging from turtlenecks, crewnecks, cardigans, and a lot more, all you have to do is just add a fireplace and a steaming hot cup of cocoa, and we’re good to go.
