This is the Quattro Air for Her full-face mask replacement headgear. There are two sizes of the Quattro Air for Her headgear: small and standard. The seamless SoftEdge Quattro Air for Her headwear has a special touch that feels more natural on your face. This helmet should be worn loosely in order for the cushion to fill. There are no headgear clips required; simply slide the headgear into the loops integrated into the mask frame. The Quattro Air for Her headgear has a "crown" strap that sits on top of the head and prevents contact with the back of the neck.
