Never run out of packing space. The Travelpro Foldable Duffel solves your packing needs as a nearly-weightless extra bag to use on day excursions while traveling and for additional packing capacity as a personal carry-on item if you come home with more than your luggage can hold.
Made from resilient, abrasion-resistant polyester fabric, this duffel folds up into its own built-in zippered pouch for compact storage when not in use.
