Why Buy Organic Sweaters and Cardigans? (What Fabrics to Look For)

These days, a lot of sweaters are made out of synthetic materials like polyester and nylon. Yes, your sweaters are made out of plastic. These materials can be problematic for a few different reasons. Some of them can contain chemicals like phthalates (BPA, for example, is a phthalate), which have been proven over and over again to be toxic to human health, fertility, and more.

Not only that, but as you wear and wash your synthetic clothing, they shed microplastics, which end up in our waterways and ecosystems and are nearly impossible to clean up and filter out. These teeny tiny pieces of plastic can not only pose a threat to wildlife but they actually have been found to end up all the way at the end of our food supply, harming humans as well.

Natural materials like cotton, wool, and TENCEL are a better option for the long-term health of consumers, our ecosystems, and the planet.

But since conventional cotton is grown using toxic pesticides and herbicides, organic cotton is even better. Organic cotton is grown and harvested without toxic synthetic chemicals, it requires less water to grow, and it is (almost always) sourced in a more ethical way in terms of the farmers involved. Look for third-party labels such as the Global Organic Textile Standard (GOTS), which indicates the cotton and the finished product has been audited and verified to meet a specific set of standards.

What about animal-derived textiles like wool? Since these materials aren’t plants grown from the grown, the organic certification requirements are different from plant-based textiles like organic cotton. Although wool doesn’t need any herbicides or pesticides to grow, you’ll want to look for brands that prioritize ethical treatment of their animals throughout their entire life, and that the shearing process is done ethically and sustainably. Labels such as Climate Beneficial, Fibershed, and PETA can help you identify wool that has been sourced ethically.

Non-Toxic Dyes

The other factor to consider is the dye used to color the organic knitwear you buy. Since many textile dyes can include toxic chemicals, you want to look for brands that use non-toxic, eco-friendly, and biodegradable dyes. These colorants are better for the wearer, the garment worker, and our ecosystems. Also look for third-party certifications like OEKO-TEX, which means the product has been tested for a long list of toxic substances.


If you’re trying to reduce the amount of synthetic material in your life and opt for organic and natural products instead, we hope this list has been helpful for you as you shop for new cold-weather clothing!
