Materials & product seals in the PETER HAHN collection

Have you ever had a look at the label sewn into your clothes? The typical information on the label reveals the composition of the fibres and all important care instructions. But often there is other important information about the garments, for example that only organic cotton has been used. In such cases, product seals and certificates help to clarify important article specifications.

Below we present the most important awards for sustainable products that you can find when shopping in the PETER HAHN fashion world.



Introduced in 1992, the STANDARD 100 by OEKO-TEX® is a recognized certification system. It is the most widely used label worldwide and governs all sorts of textile products that have been tested for harmful substances. Approximately 10,000 manufacturers in nearly 100 countries are certified by the Oeko-Tex STANDARD 100 certification (as of April 2017).

STANDARD 100 by OEKO-TEX® applies to raw, semi-finished and finished textile products at all stages of processing. STANDARD 100 by OEKO-TEX® also covers ancillary materials used. Textile products are tested for several hundred regulated individual substances from 17 pollutant classes. The standard takes into account regulated substances or those prohibited by law, such as banned azo colourants, formaldehyde or nickel. It goes further and tests for the use of substances known to be hazardous to health or that are environmentally detrimental, even if they are not yet legally regulated. As a result the test criteria and the limit values in many cases clearly go beyond national and international standards.


GOTS: organic natural fibres

Sustainable, ecological and fair: this product has been awarded the GOTS seal of approval. GOTS stands for “Global Organic Textile Standard”. This internationally recognised textile standard for natural fibres from certified biological origins is associated with particularly stringent requirements – from the cultivation of the raw materials to the processing and delivery of the finished garments.

Each phase of the manufacturing process is regularly monitored by independent bodies. Decent working conditions and the sustainable production and processing of raw materials are checked. Organic fertilisation, natural pest control, avoidance of pesticides and use of environmentally friendly dyes are not only good for the environment, but make for a real feel-good factor.



The unique properties of TENCEL™ fibres are immediately noticeable: skin-friendly and soft to the touch, with excellent breathability. The product family consists of 2 different fibre types:

1. Lyocell
The sustainable TENCEL™ lyocell fibre is manufactured using a special process. As with viscose, the raw material is derived from wood. The cellulose contained within it is extracted and processed into a fibre, in aenvironmentally friendly  closed circuit method.

Using a process developed by Lenzing, more than 99% of the solvent used in a closed cycle is recovered and fed back to the production process again and again. The same applies to the water used, which is also always recycled in a closed system. These two closed circuits are the reason for the extremely low emissions during lyocell production.

2. Modal
TENCEL™ modal is produced from the natural raw material beech using a unique process at the specialist works in Lenzing, Austria. The fibre is produced using a symbiotic process. This means that the raw material pulp is produced in the same location as the modal fibre itself. This makes it efficient in terms of energy and resource consumption.



LENZING™ ECOVERO™ viscose fibres are designed for a sustainable lifestyle and contribute to a cleaner environment as they are produced using a holistically environmentally-conscious manufacturing process. In comparison to generic viscose production, up to 50% less emissions and water pollution are caused. Also, the fibres are made from pulp which comes from responsibly managed forests. FSC® and PEFC™ certification prove that the material comes from these sustainable sources.

A dedicated system allows for the LENZING™ ECOVERO™ fibres to be identified in the final product even after long textile processing and conversion steps throughout the production chain. Thus you, as a customer, can be confident that you will find LENZING™ ECOVERO™ viscose in your products.

LENZING™ ECOVERO™ fibres have also been awarded the EU Ecolabel, an eco-label awarded to products and services that meet high environmental standards throughout their life cycle: from raw material extraction to manufacturing, distribution and disposal.


Faux fur – our contribution to animal welfare

At PETER HAHN we’ve deliberately refrained from using real fur for many years and that includes in the manufacture of this product. First, because we want to make an active contribution to animal welfare. Second, because artificial skins are of an excellent quality these days and are just as fashionable – the use of real fur therefore makes no sense.

High-quality faux furs look and feel almost the same as real fur and are therefore a real pleasure for anyone who wears them. It is of course important that you can rely on us and therefore we guarantee you that you will get only faux fur, also called “Fake Fur” from PETER HAHN.

In order to substantiate our consideration for ethics, we have been officially a “Fur Free Retailer” since 2016 – and thus part of an international initiative that already includes more than 800 companies.



Our Medima products carry the Caregora™ seal, which indicates the animal welfare of Angora rabbits. Medima condemns painful cruelty to animals during the extraction of angora wool and therefore makes sure that the rabbits are not plucked but carefully shorn. The rabbit does not feel any pain. And since not only trust but also control is important when it comes to sustainability, Medima has had its Angora wool elaborately certified. The Caregora™ seal of approval marks the first high-quality selected and certified Angora fibre, combined with compliance with guidelines for animal husbandry and animal welfare. We think this is great with PETER HAHN. And that is why our Angora pieces come exclusively from Medima.



ETERNA respects both nature and working conditions throughout the entire production chain. Made in Europe, the shirts and blouses are produced responsibly and without compromise. ETERNA makes an unequivocal promise and puts a seal on it: GOOD SHIRT. This promise can be verified by anyone just by looking for the EAN code on the sewn-in label: For all shirts and blouses bearing the seal GOOD SHIRT, the entire manufacturing process can be traced on the internet by entering the EAN code.

As the world’s first shirt and blouse manufacturer to use this verification method, ETERNA thus guarantees sustainability in the production chain and in the product portfolio. The products and their components are thoroughly tested for harmful substances, and all companies and suppliers involved in their production provide environmentally friendly and fair working conditions. This is constantly monitored by the independent Oeko-Tex institutes and ratified with the highest Oeko-Tex standard “Made in Green”.
