With 13 cubic feet of storage space, the Yakima Get Out Cargo Bag is a nice alternative to a hardshell cargo box. It folds or rolls up for easy storage, and since it attachs to raised factory side rails, crossbars or a cargo basket, you'll be able to get out of Dodge (or whatever city you happen to be in) quick as a flash. The Get Out Pro features a cross padded base for superior protection for the roof of your vehicle.
