Abstract
A seal for a respiratory mask that includes a first end portion adapted to be coupled to a mask shell, a second end portion for sealing engagement with a face of a patient, and a sidewall extending between the first end portion and the second end portion. At least a portion of the second end portion includes a textured area having a predetermined pattern. The area of increased surface roughness provides the patient contacting portion of the seal with a silky feeling to maximize patient comfort and the effectiveness of the seal without impairing the sealing ability.
