This is the fantastic Jack. It is multifunctionalal: with few easy moves, a school-travel hand luggage turns into a backpack and vice versa. The bag has a reinforced bottom for maximum protection of the backpack contentsss and you can unhook it for when you want to use it as a backpack, it is washable, large and comfortable to wear thanks to the padded back and shoulder straps. When you use it as a hand luggage, you can make the shoulder straps disappear or not. If not, thanks to the CROSSOVER SYSTEM, when you lift the extremely resistant double telescopic bar with double height adjustment, the shoulder straps are automatically raised as well, which in this way do not crawl on the ground. Lastly, thanks to the 4 wheels with 360° double rotation it is easy to drag it wherever you are.
