Blocks the Majority of the Light to Help You Sleep! [SEP] I sleep better when I wear a sleep mask, so I use them regularly. When I was looking for a new one to replace my worn out one, I was given the opportunity to purchase this one at a discounted price so I could try it out. This is a nice, light weight sleeping mask. I've had one mask before that was super thick & padded, but it was actually more difficult to sleep with. Thicker is not always better! One side is satin and the side that is against your eyes is a soft, velour type fabric. The straps are a nice, thick elastic band which is adjustable with Velcro. I've purchased many sleeping masks which have a thin elastic band that is not adjustable at all. Those eventually get stretched out before the rest of the mask is worn out. This mask does a pretty good job of blocking the majority of the light. A little light can get through the area of the mask around the nose. I don't use ear plugs very often, but it's nice to have them handy when I do need them, so I don't have to fumble around my night stand looking for them.
