This is a very comfortable mask. The first time I put it on, I was amazed at how much more comfortable it was than any of the other masks I have tried. I was so impressed, I decided to buy another one to have when the first is in the wash. Funnily enough, when I revisited the website, I saw a more detailed picture and realized I was wearing it upside down, with the chin cup on my nose. However, when I wore it correctly it wasn’t as comfortable. I have a high nose bridge and protruding nose. The chin cup forces the top of the mask cover out farther from my cheeks and does not flatten my nose as other masks do. I still wear the insert the right way around with the flexible band over the bridge. So, if you have a high nose bridge and a bigger than “normal’ nose, try it with the chin cup on top. It’s really much more comfortable that way.
