This mask is so simple to fit and use that acceptance is almost 100% at the first fit.

No mask is perfect, but F&P has come up with a real winner this time.

What we like about the ESON is . . .

1. A pioneering cushion (RollFit) that seals easily over and around the contours of your nose.

2. Stable and comfortable headgear that clips in place at the front, making it easy to put on and take off or adjust.

3. Stable and comfortable forehead support (no bumpy things or adjustments necessary.)

4. The newly revisited, extremely quiet,   diffuser pad on the elbow.
