This mask works just like it is supposed to. It blocks your vision and almost 100% of the light. It's great for sensory deprivation and for beginners, or advanced users. We use it during light bondage to increase pleasure.

This is just a simple, black, eye covering with two straps in the back to keep it secure on your head. It is the most basic design, but it works perfectly. The material feels nice and feels like it will last a long time. It is soft against the face and the straps are not too tight, at least not for either one of our heads.

The mask worked well for both of us. It fits comfortably on my head. The double straps make it easy to position and it doesn't move. Very little, if any, light came in. The only place I could find any is where my nose raised the mask slightly, but that could have been fixed with moving it some.
