and a strap separate from the liner and the respiratory mask and arranged to engage the flaps to releasably tether the liner to the respiratory mask. ### Claim 2 (depends on 1) The kit of claim 1, wherein the strap includes an elastic band. ### Claim 3 (depends on 1) The kit of claim 1, wherein each flap has a length that is between about 20% to 50% of a length from the opening to the first end or from the opening to the second end. ### Claim 4 (depends on 1) The kit of claim 1, wherein each flap has a width approximately as wide as a width of the opening. ### Claim 5 (depends on 1) The kit of claim 1, wherein the flaps are curved. ### Claim 6 (depends on 1) The kit of claim 1, wherein the flaps are formed as a reverse curve departing from a curved trajectory of the outer edge at the first and second ends of the liner. ### Claim 7 (depends on 1) The kit of claim 1, wherein the flaps are devoid of affixing material for securing the liner to the mask. ### Claim 8 (depends on 1) The kit of claim 1, wherein a perimeter of the outer edge is larger than a perimeter of the face-engaging portion of the respiratory mask for forming an extending portion of the body, wherein the extending portion is configured to be in non-adhering communication with a user's face. ### Claim 9 (depends on 8) The kit of claim 8, wherein the extending portion is a baffle for regulating the flow of air away from the face-engaging portion. ### Claim 10 (depends on 1) The kit of claim 1, wherein the flaps are aligned with the opening along a longitudinal axis of the body.
