Back up your carry-on Our duffel bag, your good companion for traveling, could be served as a gym/ sports/ overnight/ weekend/ airplane carryon/ outdoor activities/ Just In Case bag as well. How to fold it into small size When you don't use this bag, it collapses into a flat compact size, and stores after it is zipped into its compartment taking up minimal space on a shelf or in a closet. It can be packed in your carry-on to make moving around easier. Details make perfect Our duffel bag has adopted the enhanced cross-stitching (a craft stronger than normal stitching other sellers used) to extend the service life of the hand strap. All of the hardware (zipper, loops for straps, etc) are solid metal, and the straps for hand and shoulder are soft for easy-carry but also strong to hold up the bag in full.
