Now that winter has passed, it’s the perfect time to look back and see which pieces truly kept us warm (and which ones we’ll want by our side next season). Wool can be a planet‑friendly fiber when it’s made with care, from the way the sheep are treated to how the yarn is dyed. It keeps you warm, feels natural on the skin, and avoids that plastic‑y feel many synthetic fibres have.
To help you build a cozy and conscious wardrobe, we’re sharing our favorite sustainable wool brands: Dilling, Artknit Studios, The Knotty Ones, and Babaà. These labels show that staying warm and choosing responsibly can go hand in hand.
