It will fall apart within a month and the lining will pull away from the outside and the inner eye and lose material while sleeping is annoying. Still lets light in under the nose. I have a small head so it's already at max tightness and then it just gets sloppy and loses its elasticity and falls off your head. Wouldn't bother with these masks again. It's only good if you need it for a one off trip on a plane for example.
