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. The beautiful drape of the fabric is great for the oversized, relaxed fit that's perfect for tucking in. The tone-on-tone printed graphic on the front is designed by our very own Synnøve Balabanian.
