How stable is the Logical® Sleep Mask on the face?
This is a very hard question to answer as each mask is an individual and will fit only one person. However, because the Logical® Sleep Mask is an exact fit on your face, we believe it to be the most stable mask available anywhere in the world. The Logical® Sleep Mask is so secure on your face that it will dictate movement to the hose at all times and not the other way around (which can create mask leaks). The Logical® Sleep Mask only extends a few millimetres beyond the tip of your nose, making it stable in all sleeping positions. You can even change positions during sleep without dislodging the mask.
