Proface

This eye mask is by far the best at blocking out light and the most comfortable I have used yet.

And while {those two features are critical, a few other features make this mask stand out from all the other masks I have tried:
The ear plugs store directly in the mask strap.
The durability of the mask - it doesn't fall apart and the elastic doesn't get stretched out and useless.
