Best sleep mask out of dozens tried, here's why:
I've tried a lot of sleep masks from super cheap like this one to the more expensive ones like manta sleep mask.  This is the best as it meets 3 big problems with most: 1. Light blocking is awesome.  The nose, the sides, the top. It's amazing how many sleep masks don't get this right.  2. The adjustable fastener is velcro, not a buckle in the back. 3. This mask doesn't hit your eyes when sleeping.  Pressure on your eyes causes them to be red in the morning.  I'll be getting a few extra of these.
