It is important to us that our CONCEPT GREEN products are proportionately made of materials that are as natural and environmentally friendly as possible. Our goal is to have the sustainable components extended to all collection items as soon as possible.


Wool is a pure, renewable natural product. Among other things, we use recycled, mulesing-free and undyed wool. 

Harris Tweed

The Harris Tweed fabric is dyed and woven in Scotland with great care and tradition. Only 100% mulesing-free British virgin wool is used for this. Harris Tweed also refrains from bleaching wool and uses the fibres in their natural state to produce light shades of colour. The fabric produced is certified harmful substance tested at the end. You can find more information about Harris Tweed here.

GOTS certified outer fabric

Bei GOTS GOTS is a globally recognised standard for the processing of textiles made from organically produced natural fibres. The seal defines environmental requirements along the entire textile production chain as well as social criteria. The fabrics used by our weavers, such as Leomaster, Marzotto and Olimpias, must also already be GOTS-certified in order for us to be able to produce our GOTS articles from them. We ourselves are also certified with the number CERES-1038.

Recycled materials

It is not only the processing of natural fibres that is environmentally friendly, but also the recycling of raw materials that are already in the cycle. This can be pre-consumer waste or post-consumer waste, for example. We use recycled cotton, recycled polyamide and recycled polyester, among other things. An approach to produce less waste in the long term and conserve natural resources.

Certified trims and fabrics

In addition, we use ingredients and fabrics that have already been certified by our suppliers and weavers. These include certified for harmful substances tested ingredients (e.g. buttons, lining, etc.) and outer fabrics for, among others, cotton and linen or certified paper and viscose from sustainable forestry. We also use sustainably certified cotton.
