Transitioning to an organic and low-tox wardrobe is definitely a process.

Choosing non-toxic and organic clothes is crucial for people with allergies and skin sensitivities, but considering all of the different chemicals that are added to clothing throughout the manufacturing process, buying safer textiles can be beneficial for anyone’s longterm health.

To reduce stress, I recommend you build your low-tox wardrobe gradually. As your old clothes wear down, you can find healthier brands to buy from as you replace each garment, piece by piece.

In this specific guide, I’m helping you find cozy, non-toxic, and organic sweaters and cardigans for the whole family!

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

These days, a lot of sweaters are made out of synthetic materials like polyester and nylon. That means your sweaters are made out of plastic.

These materials can be problematic for a few different reasons. Some of them can contain chemicals that get dumped into our air and waterways during manufacturing, which is especially harmful for factory workers and surrounding communities.

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 the ethical treatment of their animals throughout their entire life, and that the shearing process is done ethically and sustainably. Labels such as Responsible Wool Standard (RWS), Climate Beneficial, Fibershed, and PETA can help you identify wool that has been sourced ethically.

Non-Toxic Dyes & Finishes

There’s a lot that goes into making an article of clothing besides the raw material. That’s why you’ll also want to consider the dyes and and treatments used to finish the textiles as well.

Since many textile dyes can include toxic chemicals, you want to look for brands that use non-toxic, azo-free dyes whenever possible. These colorants are better for the wearer, the garment worker, and our ecosystems.

You’ll also want to avoid labels like “stain-resistant” or “iron-free,” which usually indicates that chemicals like PFAS or formaldehyde have been added.

Although third-party certifications such as OEKO-TEX as not foolproof, they are definitely helpful—so look for those, too.

Wrapping It Up
