Abstract: The inventive subject matter is directed to an assembly of a plurality of baffle constructs which each include: a primary baffle, comprising a pliable textile, and a secondary baffle. The baffle constructs are configured to be alignable along a vertical axis relative to the ground. Each primary baffle defines a bounded, volumetric space for enclosing a first volume of insulative fill material and a secondary baffle. Each secondary baffle defines a bounded, volumetric space for enclosing a second volume of fill material. One or more of the secondary baffle are disposed in the primary baffle so that most of the second volume of insulative fill material is contained above most of the first insulative material when the primary baffle is maintained in an intended vertical orientation. The secondary baffles are mainly responsible for filling the primary baffle to its intended shape in an upper portion of the primary baffle.
