Zusammenfassung:	This invention relates to a ventilation means (120), particularly for ventilating surfaces close to or in contact with persons, wherein, the ventilation means (120) has at least one air-ducting means (122) which comprises at least a barrier layer (125), a covering layer (126) and a distribution layer (124) positioned therebetween, wherein, at least one barrier layer (122) is arranged on a side ofthe distribution layer (124) facing away from the user, and at least one covering layer (126) is arranged on a side of the distribution layer (14) facing toward a person. In the ventilation means, atleast one covering layer (126) is at least partially permeable to the air and is at least partially permeable to the steam, and the barrier layer (122) at least partially includes the air permeability lower than that of the covering layer (126).
