Your order will be acknowledged upon receipt."The Medium ComfortFit Full Face CPAP Mask Without Headgear from Drive Medical is a deluxe mask designed to provide you with effective sleep therapy every night. A soft silicone contact and frame stabilizers redistribute pressure evenly, greatly increasing the effectiveness of the therapy and reducing the risk of mask leaks. With no clunky forehead pad, this mask allows you to perform tasks in bed such as reading and watching television without the mask getting in your way or blocking your view. No forehead pad also means that this mask fits more comfortably allowing you to sleep throughout the night. The mask will fit securely with your existing headgear, making your sleep therapy treatment effective throughout the night.
