A mask (10) for supplying gas under pressure to the nasal airway of a human includes a series of flexible stretchable straps (12, 14, 16) formed from an clastomeric material for locating the mask (10) against the human face. The straps (12, 14, 16) are integrally formed or joined to define a perimeter (18) enclosing an aperture (20) adapted to fit around the nasal area of a human. The straps (12, 14, 16) are configured to approximate to the three dimensional shape of the region around the nasal area of the human face as they arm strethed, to form a tight fitting seal. The mask may be used with or without a manifold. |
