Everybody needs a few perfect sweaters in their life. And when we say perfect, we mean stylish but classic, cozy and comfortable (not itchy), and of course, eco-friendly and ethically made.

Well, good news: there is no shortage of sweaters that fit these qualifications. Below are our favorite brands that make beautiful, sustainable sweaters. But first, here’s what to look for while you’re shopping:

What to Look for in Eco-Friendly Sweaters

Natural and/or Recycled Fabrics: Unlike other fashion categories, it’s actually relatively easy to find sweaters that are 100% free of synthetic material. Even some of the materials used in conventional luxury sweaters like cashmere can be considered sustainable if sourced and processed the right way. Wool and alpaca are also two of our absolute favorite materials to wear.

Environmentally-conscious manufacturing: Again, it’s standard to find a zero-waste sweater, because the knitting process (usually) doesn’t involve cutting fabric into shapes that produce offcuts. But the processes involved in creating and dyeing yarns are often pretty harsh on the environment, using lots of water, chemicals, and energy, and leaving behind waste. Look for brands that are using more earth-friendly processes that reduce their impact, like zero-waste policies and renewable energy in their factories.

Fair labor and transparency: As with everything you buy, check for fair labor practices. Look for brands that prioritize transparency (do they tell you where their apparel is made?) and certifications like Fair Trade and SA8000. Also, look for brands that are owned by or support BIPOC.

Timelessness: If you choose wisely, a good sweater can last you decades. Look for brands that prioritize durability and timeless, versatile style. Choose sweaters that can be dressed up or down, that you can wear to the office, date night, and family dinner.

Here are the brands we recommend:



Tradlands is a high-quality women’s essentials brand, inspired by classic menswear. Its pieces are comfortable, yet timeless, with an emphasis on fit, detail, and quality. Of course, it values the welfare of its craftsmen and women all over the world, uses sustainably produced materials, and minimizes waste as much as possible. Tradlands’ sweaters are made from alpaca and/or cotton.

This brand carries super-soft cashmere sweaters for both men and women.



The scrappy Dutch brand SoGoodToWear is trying to revive traditional cashmere goat herding in Nepal. “I think if I reincarnate as an animal I would reincarnate as a goat in Nepal,” says Burger. “It was a very Buddhist approach — they were one with the goat. They would live with the goat and treat it very respectfully as a being.” Unfortunately, there are few Nepalese goats remaining and they’re ill-suited for the warming climate of current Nepal, which is more humid than in years past and can lead to moldy cashmere. Sogoodtowear imports top cashmere goats from Australia and interbreeds them with Nepalese goats. The first of these climate-resistant goats were born this summer.  Right now Sogoodtowear sweaters are 8% Nepal cashmere and 92% cashmere from suppliers in Italy and China that are certified as animal-friendly. It’s aiming for 100% Nepalese cashmere sweaters in six years.


Or Shop Secondhand

Of course, shopping secondhand is also an excellent option when it comes to both sustainability and affordability. Check out this post for our recommendations for where to look for secondhand and vintage sweaters!
