No need to tinker with this mask. Zest Nasal Mask’s innovative cushion design automatically adjusts to your face without the need for complicated adjustments, while the outer silicone seal clips in place allow for the perfect seal. The Zest features a maintenance-free Air Diffuser that disperses airflow away from the sleeper and sleep partners and minimizes exhaust noise. A breathable elastic headgear is specially designed for comfort, while Fisher & Paykel's Glider straps and clips distribute pressure equally across the face and automatically adjust the mask alignment during sleep.
