product: Invisible Urban Roller 2
category: Trolley Backpack
description: The wheels of this trolley backpack fold away when the trolley bar is pushed down, and they flip out again as soon as the bar is pulled up. Thanks to the foldaway wheel system, the backpack does entirely without an exterior fixed wheel housing and features an overall compact appearance. The trolley bars are connected to the front part of the luggage, so that the retracted handle does not put strain on the user’s spine.
