After reading many reviews on all of the blindfold/sleep eye masks, I decided to purchase this one in black (because the navy apparently ruins people's pillow cases). I have had it for almost a week now, and I am in love with it! I have never slept so well.

I sleep on my side and/or stomach, yet this mask stays in position. It is soft and pillowy, yet I can blink when it's on, which makes me think it probably does not affect my REM sleep in any negative way. Absolutely no light penetrates this mask nor creeps up from the nose area. It is all black when I put this mask on.

I feel like I am sleeping harder and waking up more refreshed as a result of this mask, and I am super incredibly thankful.

The quality of construction seems decent, and I expect that it will hold up for a long while before I need to replace it. (If it doesn't, I will come back and edit/update my review.)

I am super happy with this purchase and am thankful to all the people who took the time to review all of the eye masks. This worked out far better than I had hoped or expected. Thank you! :)
