Abstract: A portable structure defining an interior volume, and configured to facilitate draining rainwater. The portable structure includes a frame including a central support and a side support shorter than the central support. A roof fabric has a first edge coupled to the central support and an opposing second edge coupled to the side support. At least a portion of the roof fabric extends downward at the second edge with respect to a ground plane to define a concavity. An apron fabric is coupled to the roof fabric at a joint. The apron fabric is configured to extend toward the ground plane. A portion of the apron fabric defines a concave cavity that extends inward with respect to the volume of the portable structure. The concave cavity is in flow communication with the concavity to define a passage configured to drain rainwater from the roof fabric.

Abstract: A moisture diversion system is provided for a collapsible structure including a collapsible frame assembly and an outer structure coupled to the collapsible frame assembly. The moisture diversion system includes a guide strip coupled at each of a first edge and an opposing second edge to the outer structure. The guide strip defines a channel between the first edge and the second edge for facilitating diverting moisture from the outer structure.
