Contour can be a problem
I am a side sleeper. When I first put the mask on, I thought it was going to be great. The material is nice and sleek and it fit well in the strap area. It was  a little too big over my nose. When I slept on my side, depending on whether or not the pillow was in a certain place, the mask buckled and felt uncomfortable. If I put my head into the pillow and didn't move, the mask was fine. So it was ok for naps but not for all night long.<br />(The ear plugs did not work for me: they kept popping out)
