Linen is the world’s most ancient fabric. The Egyptians were already using it in the 5th millennium B.C., then it spread among the Greeks and Etruscans. Used for clothes, but also for curtains and sails for ships, it was only with the Renaissance that it became a material for shirts. It is characterized by a unique quality: the ability to absorb moisture. In fact it can absorb the same quantity of water as its dry mass.
