The classes

Recycled Cotton

Our jeans consist of up to 40% post-consumer recycled cotton, which is the highest percentage out there. Recycled post-consumer denim is our favourite material as it allows us to lower our use of virgin materials and in so doing, save water, energy and protect biodiversity. The aim to make our jeans 100% from postconsumer recycled cotton. Imagine the positive impact we can achieve then!

Our jeans are made from environmentally friendly materials; namely recycled and organic cotton. Cotton is a natural fibre, and therefore better for your body than materials that consist of blended fabrics. It’s very breathable, comfortable and hypoallergenic.

GRS certified

All recycled material is GRS certified. The GRS (Global Recycle Standard) is a full product standard that sets requirements of recycled content, chain of custody, social and environmental practices and chemical restrictions. By being GRS certified we ensure that the recycled components of our jeans are safe for our customers and the planet.

Organic Cotton

Organic cotton is grown without pesticides, insecticides, herbicides or whichever -cides are out there. The plants are non GMO, the ground it’s grown on is toxic free and is given time to recover in between harvests. In short, it’s better for your skin and the planet. Our denim consists of 60-75% organic cotton depending on the style, which is supplemented with recycled cotton.

GOTS certified

Since we want the best organic cotton out there, GOTS is the ultimate certified material. The Global Organic Textile Standard ( GOTS) is an internationally recognized organic textile standard. All the virgin cotton that we use to make our jeans is GOTS certified. This way we can ensure that the cotton we use has been harvested with the highest environmental and social standards.


We not only use organic cotton but we also triple check that it is in the jeans you purchase. The Organic Cotton Standard (OCS) verifies and tracks the organic material in the final product. All of our fabrics are OCS certified.

Paper and printed labels

To make sure our jeans can be recycled after use, we replaced the usual leather patch on jeans with a printed label. This results in the jeans consisting of one material only (monomaterial) and therefore facilitates recycling. Positive side effect: No animals are harmed in the production of our denim.

FCS certified

Our paper labels are FCS certified, which ensures us that the forests used to make the paper we used are managed in a way to preserve biodiversity as well as benefit the lives of local people and workers.
