A delivery conduit for delivering a flow of gas in a respiratory therapy system, comprising:

• an elongated wall member made of a textile material;
• and
• a support member extending along at least a portion of a length of the wall member and engaging an inner surface of the wall member, wherein the support member engages less than an entirety of the inner surface of the wall member such that a plurality of portions of the wall member are not engaged by the support member and at the plurality of portions the wall member is the only barrier to the gas within the delivery conduit, wherein the support member is a frame member provided within the wall member and engaging the inner surface of the wall member, the frame member including one or more joining members and a plurality of rib members coupled to at least one of the one or more joining members, wherein the one or more joining members comprise a spine member extending along a length of the support member, wherein the rib members have an arcuate shape and are formed in number of associated pairs located on and extending from opposite sides of the spine member, wherein in each of the associated pairs the rib members are located directly opposite one another, wherein in each of the associated pairs the rib members have a gap that separates a distal end of each of the rib members, and wherein in immediate adjacent ones of the associated pairs, the gaps thereof are offset from one another.
