Cork is a natural material that is derived from the cork oak tree, which mostly grows in the Mediterranean and Iberian region. It can be harvested every nine years from the outermost layer of the tree. Cork material keeps its unique surface structure and can be used as a vegan alternative to leather. The material is extremely lightweight, water- and tear resistant. In addition to that, a harvested cork oak tree can absorb up to five times more carbon than one that is not harvested, making the process even more sustainable.
