Glasses Fog.
I purchased the XL size and construction, quality, and fit work well for my average to large, clean shaven face.  This mask causes my glasses to fog with every breath and no adjustment, including a pipe cleaner in the top of the pocket to mold the mask around my nose seem to work.  I particularly like the way the strap extends around the back of my neck and how it can be used to tighten the fit on the ear loops.<br /><br />Sadly, I consider this a waste of money for glasses wearers, but would recommend it to those who did not wear glasses.
