Review (4/5): A night shift necessity
This mask has an elastic and Velcro strap for adjusting the fit. It is flexible and is cushioned but not too soft with a convex construction that allows for you to open and blink your eyes while wearing it. I have worked night shift for 19 years and this is the best mask I have ever worn. I sleep on my back, side and stomach and I feel it works well. A little light may come through depending on how aggressively I roll over but the mask is easily adjusted and I don't feel like my sleep is compromised because of it. My daughter said it looks like a super hero mask. She calls it my Captain Nap-time mask.
The only thing that I can say bad about it is that it does leave black streaks on my pillow BUT they do wash out. For me that is a minor issue and the only reason I gave it a 4 not a 5.
