The Soyala nasal mask is a recent addition to the U.S. CPAP market, and Somnotech has unveiled several innovative features in its design that will make it attractive to many nasal mask users.  The silicon cushion was designed through extensive computer analysis of human facial characteristics, and it provides an excellent seal.  The exhalation vent is whisper quiet and designed to direct air in a way that will make it less intrusive to bed partners as well.  The Forehead support has locking notches that allow the user to easily change the angle, but it locks down and will not change during the night.  It is also less likely to break easily than some other masks on the market.
