We were skeptical at first because they are quite thin, but after wearing it a couple of times it was very comfortable, my glasses did not fog as much as other types, and the water repellancy really works - we did a water test by running some water on the outside and it actually runs off the surface. Very good job in designing this product. The only 'complaint' we have is that it slightly itched our neck because the edging of the mask was a bit rough.
