The DreamWear Fabric Wraps are considered an optional accessory. The fabric wrap is designed to add comfort by wrapping around the DreamWear's frame (or 'cheek tubes') to provide a plush padded option.
The Philips Respironics soft fabric frame wraps are for use with all DreamWear CPAP & BiPAP Masks. This includes DreamWear Full Face, DreamWear Nasal, and DreamWear Gel Nasal Pillow Masks.
