A textured surface coating for a portion of an elastomer strap included in a headgear system is adapted to contact the skin of a patient, when in use, and the coating has a Ra value greater than zero. A vent () for use with a patient interface for delivering a flow of breathable gas to a patient includes a plurality of rises () and runs () in a stepped arrangement; and a plurality of holes () in the stepped arrangement for the venting of gas.
