Respironics Premium Headgear has a simplified design for improved comfort and durability. It uses soft, wide Lycra stretch fiber straps to provide a stable fit that stands up to long term use. It is highly resistant to fraying and curling and eliminates the stitching which can cause irritation. PREMIUM HEADGEAR is provided as standard on ComfortGel NASAL, ComfortGel BLUE NASAL, and ComfortFull 2 masks. It can also be used with most other Comfort Series masks.
