Eco knitwear is a slow fashion darling because the longevity of wool makes it one of the most environmentally friendly fibers. It is made of natural materials and lasts season after season, which only makes it so much better to invest in.

They want to change the way we consume and see themselves more as a design brand making clothes instead of a fashion brand. Do I have to say they don’t support fast fashion and see themselves as a slow fashion brand?

Why eco knitwear is better than non-eco knitwear
When can you call something eco knitwear? And why is that better than fast fashion knitwear or unsustainable knitwear?
Well, for something to be eco-approved the materials used to make the product has to be eco-friendly, and the things used in the process such as the colors used to dye your clothes need to be ecological as well.
Eco-friendly knitwear should also be biodegradable and no harmful sort of microplastic or chemicals should be used in the production. This means that eco knitwear and eco sweaters have a much less negative impact on the environment. It also has a positive impact on the people who produce the clothes, since they won’t be exposed to harmful chemicals and dying materials, which is used by many regular and cheaper knitwear brands.
All in all, this means that eco knitwear is a much more sustainable alternative to regular knitwear and sweaters.
Look for brands that care about animal welfare
When searching for your next cute sweater for the fall season remember to look for brands with the Responsible Wool Standart Mark as this means that the wool used in your sweater comes from animals who are treated well and taken properly care of.
Many animals aren’t treated right in the process of getting the wool, but by choosing brands that have a transparent and traceable wool policy you make sure you don’t support farmers and manufacturers who mistreat the animals.
Take care of your knitwear
The longer you keep your clothes the more sustainable it is, and of course, the same goes with knitwear. A way you can protect the environment is by taking good care of the knitwear after you bought it, because the longer you keep it, the more you are cutting down on clothes waste.
There are several ways to make your knitwear stay in (almost) the same condition as you bought it. As a rule of thumb, you should always wash your knitwear by hand. This way you make sure the washing machine doesn’t break the delicate fibers of the clothes. But remember that you should never twist or wring the clothes! This will break the fibers and ruin the look of your knitwear.
You should never put your delicate knitwear into the dryer/tumble and if you want to use the washing machine you should always check the label first!
