Useless size chart
This was way too small for me. The size chart, based on the description as well as using a measuring tape, puts me at the edge of a medium and medium+.  I ordered the medium+ and there was no way I could get the mask to cover my nose and reach my chin at the same time. However, my boyfriend was able to fit this mask just fine, even though he is much larger than me and according to the size chart is an XL.<br /><br />Otherwise the mask appears to be well constructed. I'll try to order it again in a larger size. I have no idea how they settled on their size chart but there are clearly some dimensions missing to help gauge fit.
