They're "ok"
My bedroom allows far too much light in the morning so I sought out a sleep mask. I figured all of them would do what seems like a simple task but I was surprised about a couple of things. The  bands that wrap around the back of your head are made of what I can only describe as standard Velcro strips of an elastic nature. The straps dig into the tops of the crevice of my ears as the edges are not particularly soft. It wakes me up regularly from the discomfort<br /><br />The mask itself, however is very soft and comfortable over the eyes but the second issues is that the eye pads don't quite conform to my eye sockets providing a good seal. The pad is flat and faces are not. In addition, when over the bridge of the nose, the nose pushes the pad out just enough to let a little light in.<br /><br />Overall, they are fine and I still gave 4 stars because I'm sure most people won't be as critical as I am being. My critical review is based on the fact I wanted and need total darkness. The don't block all of the light but the do block most of it and I'm sure most people will not notice. Perhaps I need to invest in blackout curtains.
Rating: 4 stars
