Organic Cotton

Skall Studio use GOTS certified organic cotton, ensuring the processing standards throughout the whole supply chain. Organic cotton is grown without the use of any harmful chemicals, synthetic fertilizers or soil additives and with respect for the environment and the people involved in the processes. The characteristics of organic cotton, are same or better than those of conventional cotton so it was an obvious and easy choice for us, from the very beginning.

Pure Linen

Linen is a very earth-friendly fiber because Flax - the plant from which the fiber is derived - is an inherently eco-friendly crop. It is a hardy and pest-resistant plant with low environmental impact. The properties of linen are many. It is a strong fabric, breathable and absorbs moisture well without feeling damp. In warm weather linen fabric is even able to cool the skin, making linen products extremely comfortable during the summer season.

As with organic cotton, linen is the obvious and perfect choice for at sustainable material.


Skall Studio use peace silk from India. Peace silk is made without harming the silkworms. They leave the cocoon after turning into butterflies, and only when they have left the cocoon and no longer need it, the threads are unwound from the cocoon and made into silk fabric. The production of peace silk is a cruelty free method that allows us to enjoy the beauty and the many properties of silk fabric, without harming the animals. Silk fabric is very comfortable. Light but still with strong insulation properties - warm in winter and cool in summer. And with such natural functional properties and classic beauty, silk is an outstanding material for sustainable design.


Since we launched our first collection in 2015, our knitwear has been made in Denmark. We love the beauty of pure and natural wool, and the amazing benefits of not only keeping us warm, but also being a sustainable material that can last a lifetime. The idea of making knitwear in Denmark came from our values for animal welfare. To be able to know for sure that the sheep giving us wool would be treated with care and respect. And to secure transparency by using local production facilities, made it possible for us to feel good about making knitwear in wool. 

Leftover Fabrics

One of the most sustainable choices we make is to use unique materials that are leftover or rejected, and give them a new life. When visiting our suppliers in India, we love to go through the fabrics that others have rejected, and be inspired to use them for our purpose. Yet another way of helping to reduce the production of raw materials and thus the environmental impact.
