The Rise and Hang Travel Gear is based on a collapsible shelving system. Just hang it up and pack it, then fold it up and put it in your suitcase. When you arrive, just pull it out and hang up. The Weekend Duffle Bag comes with the shelves built in, making it much more functioanl than your average bag, and also contains a hamper on the bottom for dirty clothes. The duffle bags come in blue and gray.
