The feedback we have been receiving from CPAP users about the OPUS nasal pillow mask has all been positive.

The Opus nasal pillow system is the smallest, lightest, quitest mask on the market and offers unprecendented freedom of sleep. With anatomical silicon pillows, supplied in 3 sizes (S/M/L) for a perfect fit, the slim lines of the Opus nasal pillows mask allows for any sleeping position without mask displacement.

Unlike other nasal pillow masks, the unique design of the Opus allows for 360 degree rotation of the connecting hose, which is a real bonus if you are a back and two-sided sleeper and the OFF THE LIP Pillow design allows for flexing of the pillows to ensure a SECURE FIT in the nostrils .
