1. A nasal mask assembly for providing high flow respiratory therapy, the nasal mask assembly comprising:
a nasal interface configured to deliver a flow of pressurized breathable gas to a patient, the nasal interface comprising:
a pair of nasal inserts to be inserted into nares of the patient without sealing against the nares;
a frame that supports the pair of nasal inserts and is configured to connect to a headgear assembly, the frame including a left frame arm extending away from the pair of nasal inserts and toward a left headgear connector, and a right frame arm extending away from the pair of nasal inserts and toward a right headgear connector,
a nasal interface body with one or more surfaces defining one or more fluid passageways for delivery of the pressurized breathable gas to the pair of nasal inserts, wherein the nasal interface body includes:
a barrel receiver portion integrally formed with the pair of nasal inserts;
an insertable barrel portion having a flow aperture and configured to releasably mate with the barrel receiver portion such that the insertable barrel portion sealingly connects to the barrel receiver portion for delivery of the pressurized breathable gas through the flow aperture toward the pair of nasal inserts; and
a tube connector extending from the insertable barrel portion such that, when the insertable barrel portion releasably mates with the barrel receiver portion, the tube connector portion is positioned laterally of the barrel receiver portion and adjacent to the frame;

a conduit to provide the flow of pressurized breathable gas to the nasal interface body, the conduit including a first end configured to receive a supply of pressurized breathable gas and a second end being connected to the tube connector of the nasal interface body; and
a headgear assembly comprising a plurality of headgear straps that include at least:
a left headgear strap with a left connecting end that is configured to releasably connect to the left headgear connector;
a right headgear strap with a right connecting end that is configured to releasably connect to the right headgear connector; and
rear upper and lower straps positioned between the left and right headgear straps,

wherein the left headgear strap, the right headgear strap, the rear upper strap, and the rear lower strap comprise a laminate of fabric and plastic, the frame comprises a plastic material, and the pair of nasal inserts and the barrel receiver portion comprise a silicone material.
