VITALE BARBERIS CANONICO 1663 Flannels and Covert. Vitale Barberis Canonico's Flannels and Covert bunch is a classic collection of elegantly distinguished suitings, blazers, and trousers for the colder months. This curated selection of our best-selling winter fabrics includes our heavier weight, Original Woollen Flannel which is characterized by its natural ability to drape well. Our handsome light-weight worsted flannel with some new paler plain colours for blazers and trousers. Finally, we have included our heavy-weight whipcord which is particularly suitable for sporty trousers and covert coats.
