2. The cushion of claim 1, wherein each pocket is filled with a low-viscosity medium.

3. The cushion of claim 2, wherein the low-viscosity medium is a medium selected from the group including air, oil, silicone fluid, or a gel.

4. The cushion of claim 1, wherein:

the first end portion has a sealing flap;

a number of pockets are disposed on the first end portion sealing flap;

the first end portion sealing flap includes a number of solid segments;

each pocket includes an inner wall, an outer wall, and a plenum, the plenum disposed between the inner wall and the outer wall;

wherein the sealing flap solid segments are unitary with each pocket inner wall and each pocket outer wall; and

wherein the thickness of each sealing flap solid segment is less than the thickness of each pocket.

5. The cushion of claim 1, wherein:

the first end portion has a sealing flap;

the first end portion has a sealing flap (50) with a generally uniform thickness;

the first end portion sealing flap includes a number of solid segments;

each pocket includes an inner wall, an outer wall, and a plenum disposed between the inner wall and the outer wall;

wherein the first end portion solid segments are unitary with each pocket inner wall and each pocket outer wall; and

wherein the thickness of each solid segment and each pocket is generally uniform.

6. The cushion of claim 5, wherein each pocket (40) includes a plenum and the pocket plenum has a thickness of between about 0.15 mm and 2.0 mm.

7. The cushion of claim 1, wherein:

the first end portion has a sealing flap;

the first end portion sealing flap includes an inner surface and an outer surface;

each pocket including an inner wall, an outer wall, and a plenum disposed between a pocket inner wall and a pocket outer wall;

wherein each pocket inner wall is coupled to the first end portion sealing flap outer surface.

8. The cushion of claim 1, wherein:

the first end portion has a sealing flap;

the first end portion sealing flap includes an inner surface and an outer surface;

each pocket includes a convex wall including an inner surface and an outer surface;

each pocket convex outer wall inner surface is coupled to the first end portion sealing flap outer surface; and

wherein a space is created between each pocket convex wall inner surface and the first end portion sealing flap outer surface.

9. The cushion of claim 1, wherein the first end portion includes a sealing flap, the first end portion includes a support flap, and the first end portion support flap at least partially overlies the first end portion sealing flap.

10. The cushion of claim 1, wherein the first end portion sealing flap includes an apex region, a first side region, a second side region, a bottom region, a first transition region, and a second transition region, each side region extending from the apex region, the first transition region disposed between the first side region and the bottom region, the second transition region disposed between the second side region and the bottom region;

and wherein the discrete location of a pocket is one of the apex region, the first side region, the second side region, the first transition region, or the second transition region.

11. A patient interface device comprising:

a mask including a faceplate and a cushion, the cushion comprising;

a first end portion structured to contact a portion of a patient'"'"'s face;

a second end portion structured to be coupled to the faceplate;

a sidewall extending between the first end portion and the second end portion, the first end portion including a first surface, a second surface, a number of pockets disposed between the first end portion first surface and the first end portion second surface, and a number of solid segments;

wherein each pocket is a located at a discrete location with solid segments disposed about each pocket; and

wherein the cushion second end portion is coupled to the faceplate.

12. The patient interface device of claim 11, wherein each pocket is filled with a low-viscosity medium.

13. The patient interface device of claim 12, wherein the low-viscosity medium is a medium selected from the group including air, oil, silicone fluid, or a gel.
