The present invention relates to a positioning and stabilising structure to provide a force to hold a seal-forming structure in a therapeutically effective position on a patient's head for positive pressure airway treatment of sleep disordered breathing. The positioning and stabilising structure comprises at least one gas delivery tube to deliver a flow of air to an entrance of the patient's airways via a seal-forming structure. Each gas delivery tube comprises a tube wall defining a hollow interior through which air is able to flow to the seal-forming structure, and a patient-contacting portion and a non-patient contacting portion. Both portions comprise 1) a textile material and/or a foam material, and 2) an air-impermeable material provided to the textile material and/or the foam material to make the respective portion substantially air-impermeable. At least one seam is configured to join the patient-contacting portion and the non-patient contacting portion.
