Vehicle with a air-permeable roof covering

The vehicle has an air-permeable roof cover (12) whose permeability is set between 20 and 50 percent. A bolt connects a structure (9) of the vehicle and the cover such that when a movable roof (5) is placed partly aside a position above a cab interior (3) of the vehicle, the cover is disposed above the cab interior in a removable/movable manner. The cover covers parts occupied by front/rear side windows (17a, 17b).
