Aspen and Birch trees grow fast and thick on low-grade land in central European forests, using 80% less water in comparison to cotton plants — making TENCEL™ Lyocell super environmentally responsible. The trees are responsibly thinned out, rather than cut down and then the wood is turned into a pulp. The wood pulp is dissolved in a closed-loop process with a non-toxic organic solvent, then the solution is forced through tiny holes in order to create a magical biodegradable fiber that feels softer and lighter than cotton.
