We enlarged the Milano Duffle, added some pockets and gave it wheels to create the Milano Trolley. It is made with full grain leather and 100% cotton canvas lining. The calfskin leather for this rolling luggage bag was vegetable tanned in Tuscany to create rich color tones while the semi gloss finish helps prevent stains. Over time this leather rolling duffle 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 make our leather travel bags high quality, rugged, and lightweight. Milano Trolley rolling duffle comes in four colors - Vecchio Brown, Tuscan Red, Orange, and Black. Made in Italy.
