ABSTRACT:
A breathing mask with a half mask and a nape band is to be improved such that secure contact of the mask in the entire nose and mouth region of the mask user is ensured by the nape band. The mask is thus effectively prevented from slipping despite the fact that the band is located in the nape region only. An additional application of a hood is possible without providing additional holding members. To accomplish this task, the band can be applied in the form of a rubber-elastic cuff (5) which has a neck opening (6) and a head opening (7). The mask and cuff are preferably made in one piece of silicone rubber, and the hood can additionally be bonded to the cuff.
