Interesting. Does it make a real difference the size of the mask? Based on the picture, I measured 4,5” from nose bridge to under chin (my horizontal axis is also off chart). While I’m surprised to find that I have such a large head (maybe I should be called a “cabezona" in Spanish, which also means stubborn), I find even the XL won’t fit for me. Laura
