1. A patient interface configured to supply a pressurized flow of respiratory gas to a patient's airways, the patient interface comprising:
a hollow base with an air inlet configured to be connected to an air delivery tube and receive the pressurized flow of respiratory gas, the hollow base further comprising a pair of air outlets configured to discharge the pressurized flow of respiratory gas, the air inlet being positioned inferior to the pair of air outlets when the hollow base is mounted on the patient's face;
a pair of nozzles extending from the hollow base, each nozzle being configured to receive the pressurized flow of respiratory gas from a respective one of the pair of air outlets; and
a continuous flexible adhesive strip of material configured to adhere to a side of the patient's nose and support the hollow base and the pair of nozzles on the patient's face to form a sealed airpath from the hollow base to the patient's nasal airways,
wherein the hollow base comprises a first portion from which the pair of nozzles extend and a second portion that is attachable to the air delivery tube, the second portion being more rigid than the first portion.
