Patented technology and durable quality

Vitadylan™ is made in the same innovative and environmentally friendly way as lyocell. Our raw material supplier’s nature-based production method virtually goes full circle, meeting the highest standards in terms of sustainability and quality. The technology behind lyocell is so sustainable that it has won the European Union’s European Business Awards for the Environment in the “Technology Award for Sustainable Development” category. Our secret and patented procedure is used to weave the algae and the zinc directly into the cellulose fiber. So you feel the benefit of the fabric, even after several washes.

How GREY’s patented Vitadylan™ material works

The algae used in GREY’s patented Vitadylan™ material come exclusively from the unique ecosystem of the fjords of Iceland. The algae are harvested in an environmentally friendly and sustainable selection process in which only the part above the algae’s regenerative region is cropped, to promote regrowth. The algae are left fully untreated to preserve their biological value.


Rich in essential nutrients, these algae contain more minerals, vitamins, and trace elements than any other natural product in the world. They are also high in antioxidants to protect the skin against free radicals, which damage healthy cells. Vitadylan™ contains medical zinc oxide, which is skin-friendly and anti-inflammatory. These properties are known to have a positive effect, especially on people suffering from sensitive skin or skin diseases. Zinc is probably the most important trace element for our health. It is essential for the immune system and sensory functions, and it helps to protect and regenerate the skin. Zinc oxide protects the skin against harmful UVA and UVB rays, which can damage our skin cells.


Alongside the benefits for the skin, zinc oxide has antibacterial and odor-eliminating properties to keep fabrics fresher for longer. The skin’s natural moisture releases the micronutrients in the algae and the zinc, which stimulates the active exchange between our revolutionary fibers and the skin. The skin absorbs the essential nutrients, which helps the entire body to benefit and feel good.
