Tencel is the registered trademark of Lenzing for lyocell. It is a 100% natural and highly durable material (Tencel has the European Ecolabel). Tencel is made from the cellulose of eucalyptus wood.
This wood comes from special, sustainably managed forests where a new tree is planted for each used bean. The production of the material takes place via a closed system whereby water and solvents are permanently recycled.
