A warm sweater is an indispensable staple of any man’s wardrobe.  And for many of us, when we’re considering adding a new item to our wardrobe, we want to know that the brand making it is working hard to minimize its environmental impact and support the people and communities that it works with. Fortunately, there are a growing number of brands making sustainable men’s sweaters that are committed to doing just that.

What are Sustainable Sweaters?

The most sustainable sweaters available today are made from eco-friendly materials like GOTS certified cotton, organic hemp, and a broad range of wools. Recycled versions of those same materials, as well as recycled polyester and acrylic are also often used to minimize production of new material. 

Sustainable brands work to minimize their environmental impact beyond just the materials used. Many use plastic-free or recycled packaging, offer climate-neutral shipping and encourage the donation and recycling of used garments.

And finally, brands committed to sustainability are also ensuring their employees and suppliers are being paid and treated fairly. Some brands even align their mission to include improving the lives and communities of the people who work for them.
