I have used sleep masks for years.  This mask is by far the best.  The design allows it to assure proper REM (rapid eye movement) which is needed for deep sleep. It is comfortable and does not make me hot as all my other masks have.  It is much more sturdy than any I have ever used. I will buy this product again.
