Very soft and comfortablely cooling

Only drawback: the strap is too voluminous and presses on the back of the head. Two flat straps would be even better, then the mask would sit better on the head. Still good.

Great

Totally blacks out light for good sleep, doesn't press on eyes too much, and keeps face cool. Recommend it.
