Once you try packing cubes, you’ll never go back. These simple looking organizers help you with packaging your clothes for upcoming trips by compressing the air out of them. These are not your typical vacuum bags either. These expandable cubes use a two zipper system to help eliminate the extra bulk when packing your luggage. The zippers literally compress your clothes together and eliminate wasted space. Skip the extra fees of a checked bag- eliminate the bulk and use a carryon instead!
