2. If the face is a normal face, that is the problem of wear.
Silicone-based polygon mirror with not too tight, to feel comfortable, because there will be pressure compacted underwater mirror (Imagine Le too tight and will face seal silicone mask Le deformed edge will tilt, how can not water, wear comfortable against underwater pressure will naturally mirror and face close).
