On the edge of the Bessa, on the hills divided by the Ingagna and Viona streams and dotted with small Piedmontese villages, lies Mongrando. Here, the Lanificio Guabello (now part of Biella Manifatture Tessili of the Marzotto Group) opens the doors to its historic Biella factory, where wool fabrics have been created with the same care since 1815 - a know-how that combines territory and environmental responsibility. An immersive journey: from the wool's journey through Australian farms to all the fabric processing phases and today's technological innovations. Not just a simple interweaving of threads, but the secret ingredient for men's haute couture.
