Trolley Jack ideal for every type of activity during the day thanks to its system tray. In a few simple steps you can turn the trolley to a backpack and vice versa. The cart has a reinforced base and corner protectors for maximum protection of the content and you can unhook for when you want to use it as a backpack, washable, maxi large backrest and padded shoulder straps. By trolley instead can lead to the disappearance of the shoulder straps or not. Also when you lift the durable double telescopic bar with dual adjustment height, you automatically also raise the shoulder straps, so you will never crawl on the ground. Finally, thanks to the maxi wheels from 10 inches, you can take the trolley where you want it.
