About TENCEL Lyocell

Most underwear is cotton or synthetic. Nether fabric is spun from wood. TENCEL Lyocell fibers by Lenzing, from certified and responsibly managed forests, make up 93% of the fabric.

Closed loop

99% of solvent recovered

Lenzing spins the fiber in a closed loop. Water and solvent are captured and reused instead of released.

Less water

A fraction of cotton's thirst

Wood pulp needs far less irrigation than cotton fields. The fiber starts with a smaller footprint before it is ever knit.
