The mask fits perfectly. I have adapted a rather small head (helmet size S) but thanks to the adjustable headrest, the mask is really for each head. Once set up and breathed no longer wants to sell it. She feels high-quality and which in no manner on the nose or cheeks. Even my buddy (who wear glasses) has no problems with this mask more sins to work. There is no water is formed in the mask and a pleasant breathing is ensured by the valves.
I would recommend the mask really clear.
