Abstract
A nasal mask includes a flexible shell and a seal. The flexible shell has an inlet and includes a malleable element disposed about a periphery of the shell for maintaining the shell in a user selectable configuration. The seal is disposed along a perimeter of the shell so as to form a chamber within the shell when the mask is donned by a user.
