This is the adjustable Easy Release Headgear (straps) with Clip & Tri-Glide Buckle that comes standard with all FlexiFit 432 (HC432) Full Face CPAP/BiPAP Masks.
It is identical to the headgear used for the FlexiFit 431 except for the label, indicating the mask design, on the back of the headgear.
A Tri-Glide Buckle, which connects the two headgear straps at the back of the head for easy adjustments, is included.
