RollFit Nasal Seal (Cushion): The Eson's RollFit Nasal Seal (Cushion) rolls back and forth on the nose during sleep creating a soft, effective seal while increasing comfort and minimizing pressure points -- especially at the difficult-to-fit nasal bridge. Integrated soft, silicone stability panels optimize sealing performance and enhance stability all night long.

ErgoFit Headgear: Eson comes complete with breathable, ergonomically designed ErgoFit Headgear. ErgoFit headgear is designed to self-locate high on the rear of the head, allowing for maximum head movement and minimum mask drag. Embedded Velcro Tabs with Easy-Clip Hooks make fitting and removal fast and easy. Two headgear sizes are available: All Small Eson masks come standard with Small ErgoFit Headgear. All Medium and Large Eson masks come standard with Medium/Large ErgoFit Headgear.

Easy Frame: Eson's low-profile 'Easy Frame' is stable, durable and small, and ensures a clear line of sight. One frame fits all three seal sizes and has an Easy-Clip frame attachment to aid assembly after cleaning.

Quiet Air Diffuser & Swivel Elbow: Eson includes a "Q Cover" elbow vent for super-quiet air exhalation and minimal partner draft. The ball-and-socket elbow rotates for freedom of movement while minimizing drag from your CPAP or BiPAP tubing.
