Review (5/5): I LIke It
This is the most comfortable sleeping mask I have (its better than my other five, including a memory foam mask). There is a pleasant aroma when opening the mask, it goes away after using it a few times. What I like about this mask is that it is both comfortable and form fitting (goes around the nose to block noise and has a soft fabric that adjusts to the face).
I find that doubling sleeping masks tends to produce the best darkening effect as well as a cupping of the face. For "doubling" I've found that using a heavier bulkier mask on the outside seems to work more effectively.
