Last Updated on May 5, 2023

It’s sweater weather! Get cozy with these sustainable sweaters and knitwear.

Wondering what the difference is between alpaca and cashmere, or if wool is even an ethical choice? Check out this companion post all about wool — its fibre properties, the ethical considerations, and what to look for to make more responsible and cruelty-free choices.

The brands I’ve picked have a variety of materials and different approaches and transparency around their ethics, so I think you’ll be able to find something that speaks to your style and values.

Sheep Inc.

A new fave, Sheep Inc. is a brand with classic cuts, great color options, and strong values. They do a great job providing information and transparency about their farming and manufacturing. As a cute bonus, each piece even comes connected with a sheep — you can see the GPS location of the farm it lives on.

Their pieces are made in a solar-powered factory in Portugal where employees are paid a living wage. I also appreciate that they care about their products lasting as long as possible, and include good clothing care info as well as a little sweater comb to keep your knits looking their best!

Sheep Inc.’s knitwear is made from ZQ certified merino wool (the best animal welfare standard currently available) farmed with regenerative practices.

Amour Vert is great for both basics and more stylish pieces. Their sweater styles range from oversized fits to wrap cardigans, to cute puff-sleeved pieces in neutrals and colours.

Izzy Lane’s wool sweaters are made from their own flock of rescued sheep who will live out their lives on their pasture.

Don’t Forget Secondhand!

Thrifting is wonderfully sustainable and also a good way to ensure you’re not supporting unethical practices.

Here are our favorite places to buy secondhand clothing.

Knit Your Own

Knitting is a fun and fulfilling project, and you can make exactly what you want!

One of the best things you can do is to source local wool from sustainable and responsible farms or local yarn stores. It’s a wonderful way to support small businesses and oftentimes you can even visit the farms. Check if there is a Fibershed near you where many farmers also use regenerative practices.

We also have a roundup of sustainable fabric and yarn stores!

Wool and the Gang

Wool and the Gang is great if you’re looking for cute and trendy styles, with everything you need to make your own sweater!

Some of their yarns are definitely better than others, and for sustainability and ethics we’d recommend sticking with their upcycled or organic cotton and hemp blend yarns.
