Review (4/5): Good sleep mask
This is a good sleep mask. It has a mild scent right out of the box, but isn't noxious. After some use the smell goes away. The mask is washable which extends its life. It blocks out light well, and isn't too annoying on the back of the head. Once adjusted it stays on most of the time. They seem to last me about 3 months if I wash it occasionally. Subscribe and save is worthwhile if you like it as they do wear out in a few months.
