A nasal mask (1) includes a flexible shell (4) and a seal (2). The flexible shell (4) has an inlet (8) and includes a malleable element (6) disposed about a periphery of the shell for maintaining the shell in a user selectable configuration. The seal (2) is disposed along a perimeter of the shell (4) so as to form a chamber (80) within the shell when the mask is donned by a user. <IMAGE> |
