1. A headgear assembly used to secure a respiratory interface to a head of a user, the headgear assembly comprising:
a first strap portion; and
at least one connecting strap assembly, comprising:
a relatively inelastic connecting strap; and
a relatively elastic connecting strap,
wherein the relatively inelastic connecting strap is at least partially integrated with the relatively elastic connecting strap,
wherein the relatively inelastic connecting strap is fixed to the first strap portion at a first end of the relatively inelastic connecting strap, and a second end of the relatively inelastic connecting strap is connected to the respiratory interface via an adjustment mechanism such that the relatively inelastic connecting strap provides a connection between the respiratory interface and the first strap portion,
wherein the adjustment mechanism allows a connection length of the relatively inelastic connecting strap between the first strap portion and the respiratory interface to be varied,
wherein the relatively elastic connecting strap comprises a passage that extends from the first end to the second end and within which the relatively inelastic connecting strap is disposed.
