Stretchgear Headgear: Stretchgear Headgear is made of comfortable and breathable elastic, specially designed to maintain a firm seal. The headgear also includes a glider clip and hidden strap release feature that offers simple one-step removal of the headgear. No more ongoing headgear adjustments required!

Maintenance-Free Air Diffuser: The FlexiFit 406 features a maintenance-free Air Diffuser that disperses airflow away from the sleeper and sleep partners and minimizes exhaust noise.

Sleek Cushion Design: Using anthropometric measurements from an exhaustive database of facial specifications and contours, Fisher & Paykel redesigned and improved the cushioning and silicone seals on the FlexiFit 406 to create a better fit with fewer pressure points.

One-Step, Easy Fit & Mask Removal: The new strap releases on the FlexiFit 406 are designed to make removal and cleaning easy and allows reassembly without having to adjust the fit! The unique glider strap allows for more freedom of movement during the night and also helps prevent the mask from moving around your face.
