Works great and comfortable too!
This is my second sleep mask and I've been surprised at how much better I sleep with one.  I guess I never knew the extent to which ambient light was disturbing my sleep.  The velcro strap makes this mask easy to size, the fabric is very soft and the biggest improvement over my other mask is the enhanced eye cups. By extending out the eye cups the mask doesn't press against my eyes or leave any marks, and it does a better job of keeping out light, especially at the bridge of the nose.  At the price it's a great value too.  Highly recommended!
