I've never seen anything quite like them on a backpack, but they're a wonderful feature for carrying long and unwieldy objects without having to worry about them falling off your pack

It is also very breathable, so theres no chance youll suffocate

That said, today even larger pieces like trunks and checked bags tend to have four wheels
