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. Just avoid acrylic, a synthetic, fossil-fuel product.

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. As traditional items, sweaters lend themselves to artisanal origins. If not made in a workshop, look for brands that prioritize transparency and certifications like Fair Trade and SA8000. Also, look for brands that are owned by or support BIPOC designers.

Timelessness: If you choose wisely, a good sweater can last you decades. Look for brands that prioritize durability and 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:
