Seamless SoftEdge Headgear for Quattro Air series masks features premium rolled-edge fabric with a unique texture that helps improve fit and feels more natural on the face. It should be worn loosely to allow the mask cushion to inflate and adapt to facial contours and movement through the night. The headgear's crown strap sits comfortably at the top of the head, limiting contact with the sensitive areas around the back of the neck

This headgear is available in two sizes. Standard sized headgear comes with all Quattro Air Masks; the small size can be purchased separately
