Why Shop For Sustainable Sweaters?

There’s more than one reason why a sustainable sweater brings the warm fuzzies! First up, eco-friendly sweaters usually use materials that are gentler on the planet, like organic cotton, recycled fibers, or responsibly sourced wool. 

These materials use fewer resources than traditional production: organic cotton reduces pesticide and water use, and recycled fibers save precious resources and cut down on waste that might otherwise end up in landfills.

Then, there’s the energy and emissions factor. Sustainable sweater brands often focus on reducing their carbon footprint by choosing cleaner energy sources, shorter supply chains, or manufacturing locally. That means each sweater has a smaller environmental impact, helping reduce greenhouse gas emissions (and contributing to a healthier planet for all of us).

Sustainable sweaters are often made by brands that ensure fair wages, safe working conditions, and dignified treatment for garment workers, so each sweater and cardigan supports a better fashion system. And because sustainable brands tend to emphasize quality, you’re getting a well-made sweater that won’t stretch, shrink, or pill easily, giving you a long-lasting piece you’ll wear year after year.

Choosing a sustainable sweater is about more than looking good; it’s a chance to wear your values proudly, knowing your cozy purchase is as gentle on the earth as it is on you!



Our Sweater Criteria

Sustainability is a journey, not a destination, and each of these brands has made significant strides in the fashion industry to support our environment. Yet, they continue to push boundaries and strive for even greater improvements. The companies on our list utilize sustainable materials, implement eco-friendly practices, and maintain transparency about the life journey of their clothing. Together, they are setting a new standard for responsible fashion!

Materials |

We look for fibers like GOTS-certified organic cotton, luxurious alpaca wool, or innovative TENCEL™ made from sustainably sourced wood pulp.

Recycled materials, such as recycled polyester made from plastic bottles, are also fantastic options– reducing waste and giving new life to discarded resources.

The focus is on natural, biodegradable fibers that are hypoallergenic and gentle on your skin, ensuring that your cozy knitwear is kind to both you and the planet!

Eco-Friendly Practices |

From utilizing low-impact dyes and natural plant-based alternatives to supporting ethical labor practices and fair wages for artisans, these brands prioritize the well-being of their workers and the environment.

Many brands also implement water-saving techniques, energy-efficient manufacturing, and packaging made from recycled or compostable materials. 

Transparency |

The best brands are open about their sourcing, production methods, and the people behind the seams. They share the story of where their materials come from and the artisans who create their products, ensuring fair treatment and working conditions.

We look for brands that provide detailed information about their supply chain and are certified by recognized organizations, such as Fair Trade or B Corp.
