The Cargo Hauler Duffel 90L/L is a beast of a bag with all the right straps in all the right places. This giant duffel is perfect for long vacations or worldwide jet setters. Rough and tough is the name of the game with heavy-duty tie-downs for strapping to the roof rack for the ultimate road trip.
