Whether you're an adventurer or a meticulously planned vacationer, this trolley is designed for anyone who loves traveling with good friends. This backpack was specifically created for these people. Who hasn't experienced the struggle of dragging a trolley or suitcase over gravel and uneven ground while on vacation? How much easier would it be to simply throw the trolley on your back for a short carry? Conversely, when you're traveling with a backpack and covering a long distance on asphalt, it would be great to easily pull it behind you. Just pull out the shoulder straps, and you have a backpack. Snap them back in, extend the telescopic handle, and you have a trolley again.
