We bear responsibility for our planet and the next generations.


A large proportion of our products consists of cotton. The cultivation of conventional cotton comes often along with enormous water consumption and the use of genetic engineering and herbicides. For this reason, we made a conscious choice to use cotton from sustainable cultivation. For 100% of the cotton of the autumn / winter 2021 STUDIO collection we obtained the “Better Cotton Claims Units”. The selection of our accessories such as buttons, yarns and interlinings also follows a consistently sustainable approach.

Production plants

Our own production sites as well as our partner companies and fabric suppliers undergo regularly independent audits or certifications and meet the highest international, social and ecological standards.


We place a high emphasis on our environmentally friendly packaging and the selection process of our shipping options. Concrete objectives are the most climate-neutral distribution from our production facilities to our customers worldwide, the use of environmentally friendly cardboard packaging made from recycled materials and the elimination of plastic. Our packaging consists of biodegradable materials, the labels of recycled yarn. Our hangtags are “Forest Stewardship” (FSC) certified.


We have the firm conviction that positive and far-reaching changes in social and environmental conditions are only possible if we stand up for this project together. An open exchange with all stakeholders is essential. For this reason we have joined various initiatives and rely on the expertise of independent standard organisations. All products meet at least one criterion for each level of the value chain.

ClimatePartner is one of the leading providers of climate-protection solutions, including climate-neutral packaging. Together with ClimatePartner, we have determined the CO2 emissions that result from the manufacture of our shipping boxes. By supporting a project for forest protection in Papua New Guinea, we can offset the emissions and make production climate neutral. With the use of climate-neutral shipping boxes and the support of climate protection projects, we are making a contribution to the Sustainable Development Goals (SDGs) of the United Nations.
