What is eco denim?
When we talk about eco-friendly denim and sustainable jeans, we are referring to pieces that are not pre-treated, made from water-saving organic cotton, recycled materials, or made with energy and water-saving technologies.
The Jeans Redesign project has set out guidelines to solve denim’s biggest environmental issues, and while not all brands have made real changes to their manufacturing practices, looking at the project’s members might give you an idea of which companies to support.
