This mask is very comfortable, but I found that I had to breathe through my mouth because the portion where the nose goes is a little too narrow for my nose. I started wearing the mask with Breathe Right strips, but this caused the mask to ride up and allow light under the cushion. My nose isn't THAT wide, but the nose portion is narrow enough to cause some discomfort. If you have a narrow nose, this is the mask for you. It checks all the other boxes: comfortable, total darkness, easily adjustabSee full review
