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 user, and a sidewall extending between the first end portion and the second end portion. At least a portion of the second end portion along at least a portion of a perimeter of the second end portion includes a textured area having a first rms surface roughness that is greater than a second rms surface roughness of a non-textured area of the seal. The area of increased surface roughness provides the user contacting portion of the seal with a silky feeling to maximize user comfort and the effectiveness of the seal without impairing the sealing ability.
