Sustainable Knitwear to Keep You Warm and Cosy - Good On You
18 Feb

Sustainable Knitwear to Keep You Warm and Cosy

We don’t know about you, but knitwear is one of our favourite things to don on those cooler days when we just want to be warm and cosy. Knits are one of those fashion items that have the double benefit of being super comfortable while looking effortlessly stylish. They are also diverse, and can match as easily with a flowy dress or skirt as with a pair of jeans or tights.

For sustainable knitwear, you want to look out for fabrics that treat the planet right. Rather than damaging polyester or acrylic, opt for recycled wool like from Näz (Portugal), or organic cotton from tentree (Canada). For more ethical knitwear that prioritises workers and animals, this fair trade knit from LANIUS (Germany) or vegan knitted scarf from Kowtow (New Zealand) are great options. Whatever your brand of cosy, these ‘Good’ and ‘Great’ brands are here to help for this season and many to come.
