I get up very early in the morning for work and sometimes in the afternoon I need a quick nap between classes/ work/ whatnot. I have used so many different sleep masks over the years and most of them simply did not work. They let through light, they didn't conform around the nose to block out light, they slid off my face because they were satiny, etc. Then I ordered this mask based on other reviews- an excellent decision. Soft, but not the kind of soft that makes your face warm or sweaty, padded under the eyes to block out light, and an adjustable strap for my giant head.  And seriously, at just over $6, can you beat it?
