Invisible Urban Roller 3.0 is designed for one- or two-day business trips. This laptop backpack comes with unique patented retractable roller wheels. The wheels are hidden or popped out by pushing or pulling the telescopic handle, thus preventing dirty wheels from staining your suit. It has a main compartment to hold your working gadgets and belongings, and a back utility compartment for clothes and travel essentials. A special pocket hides the shoulder straps to prevent them from dragging on the floor when the roller wheels are in used.
