transparency is an integral part of a sustainable future


The Befriend the Sun shirt was part of our SS23 collection, which for the first time was entirely designed and sewn locally in the Czech Republic. Read where it comes from and how the material it is made of is processed.

Linen is made from flax fiber. The flax season begins in March when the seeds are sown, and after 100 days, usually between June and July, the harvest begins. During August, the most important part of the process begins - uncorking - and nature plays a huge role in this process. The farms where our flax is grown are in Northern France and Belgium.

After harvesting, the fiber must go through shredding and combing. Fiber quality is assessed manually. The weaving and spinning process takes place in Poland. In weaving mills that are powered by renewable green energy.

The linen fabric is then put into a machine where the shearing knives remove the last remnants and impurities. This step is essential for a perfect finish. Cutting dust is collected and recycled. It can be used to make paper or insulation. This last stage of processing takes place in Belgium. Our supplier is the Belgian company Libeco, which has been a traditional flax processor in Europe since 1858.
