A mask (10) for use with a system for supplying breathable gas pressurised above atmospheric pressure to a human or animal's airways. The mask (10) includes a mask shell (12) which is, in use, in fluid communication with a gas supply conduit (30), and a gas washout vent assembly (20). At least the region of the mask shell (12) or conduit (30) surrounding or adjacent the vent assembly is formed from a relatively flexible elastomeric material.
