This patented compressible packing cube is designed as part of a packing system that is affordable, organizes your life into smaller space and can even help you save on airline baggage fees by getting you into that carry-on luggage versus a larger bag. the ultra-lightweight cube measures 15 x 11 x 5 inches. this packing cube zips to compress your packed clothes by nearly half. this compression factor allows a load that would normally require "check in" to become "carry on" when combined with a kiva 21 inch roll aboard, when combined with multiple cubes. great for clothes, but also perfect for organizing your electronic cords - keeping them from getting tangled in your bags. ideal for backpackers too!
