Core Performance Benefits High-Definition Field of Vision: The Siesta frame is engineered without a forehead support bar, providing an entirely open view. You can wear your glasses, read a book, or finish a movie comfortably before turning in for the night. Fluid Movement Swivel: Equipped with a 360-degree rotating elbow, this assembly allows for maximum freedom. Whether you sleep on your side or toss and turn, the swivel manages the tubing to prevent tension and mask drag. Contoured Silicone Seal: The included nasal cushion is made from hypoallergenic, medical-grade silicone. It is designed to “self-adjust” to the bridge of your nose, creating a soft but secure barrier that stops leaks before they start. Silent-Flow Venting: The frame features a built-in air diffuser that breaks up exhaled air into tiny, silent streams—directing it away from you and your bed partner for an undisturbed night.
