A wheeled luggage case is provided with a retractable handle (4) assembly that is withdrawn from the interior of the case to an extended vertical position, from which it is angularly rotated by the user to a position that minimizes the vertical force required to comfortably tow the luggage. Preferred angular displacements for a wide range of users and loads have been found to be at about 17° and 35° from the vertical position. Optionally, the handle assembly (4) can be provided with telescoping legs for greater versatility.
