I call this a coma mask, instead of a sleep mask, even with a spouse, child and pet in the house, this sleep mask helps me to drift off quickly, and sleep longer in the early morning when the sun rises before I do in the summer.
It's soft against your eyes, wraps around your ears, comes with decent earplugs which can help you drift off into an undisturbed land of nod for a sleep which feels like a one week holiday. Very restful sleep can be had with this sleep mask.
The soft material will leak the blue dye onto your pillowcase, so be mindful of which pillowcase you use for the first few nights of sleep, especially in hotter summer nights. I have not tried to wash the mask as yet, I'd suggest a cold hand wash initially/
