Schwanen was revived by Gitta and Peter Plotnicki to carry forward the legacy of the original Balthasar Merz textile mill. Using century-old loopwheel machines—some dating back to 1889—the brand focuses on authentic heritage construction, high-quality organic materials, and environmentally responsible production. Every component, from fabrics to threads and labels, reflects their commitment to traditional craft and sustainable manufacturing.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Merz b.
