I don't use sleep masks, but my boyfriend loves them because some times he has to sleep during the day. I got this for him to try out and he liked it a lot. He found it to be really comfortable to wear and blocked out all light. He only wishes that it was a little tighter because after he falls asleep it has a habit of popping off and he prefers to wake up with it still on. This product is available on Amazon . I received this product at a discounted rate in exchange for a honest review.
