A facial sealing segment for a respiratory device includes a sealing flap adapted to sealingly engage the face of a user. The sealing flap is disposed about, and defines, a cutout adapted to receive one or both of the mouth or nares of the user. The facial sealing segment further includes a number of selectively removable portions formed in the sealing flap about the cutout. Each removable portion is defined in the sealing flap by a tear portion. |
