Protective cover, particularly for vehicles

The device has at least two layers joined at the edges in a pressure tight manner, preferably a cover layer and a contact layer, of material that is impermeable to air. The layers are essentially parallel when pressure is applied. The rollable cover has at least one, preferably two preferably integrated attachment bands (8) whose length corresponds to the cover and that can be rolled up with the cover so that the cover can be unrolled very rapidly over the object by pulling in the unrolling direction (9).
