Milano Trolley is made with full grain leather and 100% cotton canvas lining. The calfskin leather for this bag was vegetable tanned in Tuscany to create rich color tones while the semi gloss finish helps prevent stains. Over time this leather bag will soften and develop a beautiful patina. Our 8 oz cotton duck canvas lining is made in South Carolina and very durable. The combination of Italian vegetable tanned leather, Italian craftsmanship, and U.S. made canvas lining.
