Tij (57) Abstract: A patient interface including a seal-forming structure with a textile membrane that has at least one hole such that the 
flow of air at a therapeutic pressure is delivered to at least an entrance to the patient's nares and/or an entrance to the patient's mouth.  
The seal-forming structure is constructed and arranged to maintain the therapeutic pressure in a cavity of a plenum chamber throughout 
the patient's respiratory cycle, in use. The textile membrane includes a first portion that is held in a relaxed state and a second portion 
that is held in a taut state. The tautstate of the second portion is configured to allow the seal-forming structure to include a three
Odimensional shape that has multiple curvatures.
