I just got off the glacier on a Denali expedition and picked this item up last minute. I taught myself daily saying how it was my favorite piece of equipment that I brought on the trip. I wore it different from the picture, with it stretched out over my head and chin. This left the opening flap just under my nose. I was still able to breathe and now I had sun protection from the reflection off the snow under my nose as well. It is the only piece of gear that I used every day one the trip and I highly recommend taking one on you're next glacier expedition.
