A boot for a hydraulic, hydropneumatic or pneumatic piston-cylinder unit, in particular for vibration dampers or spring struts for vehicles, covers a portion of a piston rod that projects from the cylinder of the piston-cylinder unit. To protect against dirt and/or damage, the boot is arranged between the end of the piston rod and the cylinder. The interior space of the boot undergoes a change in volume due to the relative movement of the piston rod and cylinder with respect to one another. At least one flow connection is provided which leads to the interior space of the boot and allows for air flow in and/or out of the interior space. The at least one flow connection is at least partly covered by an area of the boot.
