More about Oeko-Tex

Oeko-Tex Standard 100

Your clothing lies directly against your skin. The area between the skin and the fabric is an unpleasant environment where sweat, heat, cold and friction can all prevail. This explains why textile safety is important to us.

Our socks, underwear and T-shirts have Oeko-Tex® Standard 100 certification and are therefore 100% skin-friendly and allergy-tested.

Why Oeko-Tex?


Why the standard was introduced

The Oeko-Tex® Standard was introduced in the early nineties as a response to the general public’s demand for textiles that did not pose a risk to health. Since then, the Oeko-Tex® Association – made up of a series of independent testing bodies – has been guaranteeing safe textile products.

The Oeko-Tex® criteria catalogue provides a consistent, scientifically sound benchmark for the evaluation of potentially hazardous materials in textiles for companies in the textile and clothing industries.


Skin-friendly socks

Quality is our priority. Our socks are therefore made of high-end materials and undergo regular tests.

Discover your favourite socks and enjoy a 100% skin-friendly, comfortable fit.
