Comfortable if you have a smaller head
I wear glasses full-time and have to wear a behind-the-ear headset for work and there just isn't enough room for a facemask string, so I purchased these headbands.  I'm a big girl there for I have a larger head.  The concept is good however, the band it too tight on my head and pulls when I have the facemask attached.  I let a friend of mine that is quite a bit smaller than I am and she did not have any problems.
