The suitcase comes with all the important features you need when traveling. The special rib cage construction is inspired by the human rib construction and is made of strong and lightweight ABS ribs that provide support and protection. The suitcase also comes with the unique Hook-Up System, which allows you to easily strap a smaller suitcase onto the Little Bastard to take the strain off your shoulders. On top there is still a really simple handling. The wheels are big and stable and the handles on the top, bottom and side guarantee best navigation. FeaturesRib cage constructionhook-up system
