Exceptionally Quiet Performance: Zest Q masks minimize partner disturbance with advanced Air Diffusers. The refined Air Diffuser design ensures minimal noise and soft, draft free, exhaust dispersal. Use with the special Q Cover for extra quiet or without, for a simple, maintenance-free option.
Auto Contouring Cushion with VTS Silicone Seal: Zest Q's auto-contouring, FlexiFoam Cushion was developed with the help of an exhaustive facial measurement database. The unique cushion materials automatically adjust to a wide range of facial contours providing support and seal without pinching or pressure. Working in concert with the cushion, Zest Q's ultra-soft, smooth Variable Thickness Silicone (VTS) Seal snaps on to improve seal and comfort.
Anti-Leak, Adaptive Glider Straps: At the base of the Zest Q a sliding Glider Strap adapts to movement, turning and shifting during the night to maintain a secure, leak free seal without requiring manual adjustments or creating pinch and pressure points.
