Systems and methods for making a custom sleep apnea mask or other wearable article are disclosed. The sleep apnea system comprises a face mask, a headband integrally connected to the face mask, and at least one air duct configured to direct air from the CPAP machine to nasal tubes. The face mask preferably comprises: an inner surface having the same shape as the user's face; an upper surface configured to sit at a first predetermined distance between the user's nose and eyes; and an outer… Show more

Systems and methods for making a custom sleep apnea mask or other wearable article are disclosed. The sleep apnea system comprises a face mask, a headband integrally connected to the face mask, and at least one air duct configured to direct air from the CPAP machine to nasal tubes. The face mask preferably comprises: an inner surface having the same shape as the user's face; an upper surface configured to sit at a first predetermined distance between the user's nose and eyes; and an outer surface configured to extend a second predetermined distance from the inner surface. Nearly shape and position of substantially all the surfaces of the mask are configured based on the shape and or location of facial features, resulting in a highly customized mask optimized for each individual patient.
