Almost new black Monos Metro Duffel bag with QuickSnap classic kit and dust bag. Used two times then hurt my back and had to switch to a book bag style. From the Monos site- With a sleek profile and water-resistant nylon twill with vegan leather details, the Metro Duffel is the perfect multi-purpose companion for everyday travel – from daily commutes to weekend trips. The Metro Duffel features our unique QuickSnap™ Modular Kit System, allowing the interchangeable Metro Kit to be easily added or removed to suit your needs. The duffel’s roomy interior is designed to keep all your essentials organized, with a sleeve that fits up to a 15-inch laptop and inner side pockets that allow for easy access to your water bottle or compact umbrella. The built-in trolley sleeve fits securely around the handle of any Monos suitcase for seamless pairing, and converts into an extra pocket when not in use.
