Our new FOSS quality is a 50/50 mix of merino and Lyocell fibers from TENCEL™ . Lyocell fibers are derived from sustainable wood sources – sustainably managed forests. Wood and pulp used by the Lenzing Group is harvested from certified and controlled sources. This piece has a slightly loose fit. Wear it in the same way as your favorite basic tee: with tailoring and jeans alike.
