The top, bottom, first side, and second side sheets provide an inflatable air duct having an inflated state and a deflated state. The inflatable air duct has an inflated length greater than an inflated width. The inflated width is more than twice as great as an inflated height. The interior of the inflatable air duct defining an air passageway having a first airway, a second airway, and an intermediate airway. The intermediate airway is adjacent the first airway at a first transition area. The example air duct system also includes a second transition area between the intermediate airway and the second airway.
