The dress has a tube (400) supplying a ventilation fluid from the interior (2) of a suit (1). A conduit (40) evacuates the fluid after it ventilates a part of the interior (2). A connection unit (50) connects the suit`s interior with the conduit`s interior. The unit is formed of a sealed passage (51) provided in center of a bottom wall (22) of a helmet part (11) of the suit. A valve (60) is mounted in cooperation with the conduit or the passage so that the valve passes in a direction passing from the suit`s interior towards the conduit`s interior and is blocked in a reverse direction.
