Quality 45

For our snugly woollens we only use finest, untreated merino wool. Wool balances temperatures, can absorb up to a third of its own weight in moisture without feeling damp while letting the skin breathe. Its high natural lanolin content has an antibacterial effect. Usually, it’s enough to air our woollens regulary and only handwash them from time to time at a max. of 30° C with a mild woolshampoo and reoil them with lanoline-cure. Our woollens are made without chemical treatments (chlorine chemistry).

To avoid moth, please use lavender or cedar wood pieces.
Care: Handwash at 30°.


Wool / Cotton

Quality 48











With our new quality mixture from ecologic fibers in
60 % wool and 40 % cotton K.b.A., we achieved
to combine the advantages of both fibers.

But the mixture need special treatment, because we do not
finish our qualities with chlorine etc..Wool offers a high
wearing comfort by its special characteristic, however it is very sensitive.

Because of it a special structure wool is highly influenced by
mechanic treatment especially when it if wet (while washing).
The mixture with cotton combines the nature of both fibers.

We use cotton from controlled ecologic production in worldwide projects, Certified by CERES, ECOCERT or Control Unions Certifications.


Neither in cultivation nor in harvest or Manufacturing there are used toxic elements. Our all-natural cotton offers a higher stability and durability to your garment by the mixture. The structure of wool offers a comfortable climate to your body, while cotton supports it by an air film and creates a warmth store.


At the same time cotton transports the humidity to the wool which emits it to the air. By this mixture we achieved a machine washability up to 30 ° C. Above all we achieve this without using other methods, which are applied even in the ecological area to make wool washable.



Wool / silk

Quality 71

Our merino and mulberry silk mixture (70% wool/30 % silk) combines all the advantages of wool and silk. Wool keeps us warm, is water and dirt repellent. Silk is soft and gives our skin a feeling of wellbeeing. This mixture is especially recommended for sensitive skin.
Care: Handwash at 30°.

Silk / Wool-Cotton

Quality 91

We know the problematic of the hand wash in today’s time. Therefore, we developed a special yarn-mixture which corresponds to our wool, silk and organic cotton we already use.

The result is a fabric made of 20 % silk, 35 % wool and 45 % organic cotton, manufactured after strict ecological guidelines. You can machine wash our new quality at 30 degrees (no spinning, no tumpler!)
People with sensitive skin stand this all-season soft material-mixture very well and the shrinkage-results after machine washing are really very satisfying

Mulberry Silk

Quality 13

Untreated silk is skin-friendly and balances temperatures. It is cool and fresh on hot summer days and warm in winter. It soothes and relaxes and has beneficial effects on allergic and sensitive skin. The thread of the silkworm shines soft and is extremely fine. Our quality is very smooth, fine yet elastic.

Care: Silk regenerates best in fresh air. This natural fiber is washed with plenty of water and by hand.



All of our underwear is manufactured with care and the environment in mind on the „Schwäbische Alb“ (South Germany).


Cosilana is using yarns that are certified by GOTS and produced with natural processes. Therefore it is possible that your garment shows structural defects just like a example the woolen fur of a sheep. These structural defects and impurity fibres are proof of a sustainable production. They are no quality deficiencies and cannot be accepted as complaint.


We guarantee highest quality standard. Our natural fibres are residuechecked and controlled regularly by an independent ecology-institute. In January 2006 we joined the IVN-control-system*. Please do not hesitate to contact us for further information.
We wish you many good experiences with our underwear
