ABSTRACT:
A portable bivouac shelter (10) is provided having an end pole (48) retaining on the top sheet (12) through a tunnel (46) for holding the top sheet (12) in a taught and semi-circular configuration. This permits the top sheet (12) to be held away from the bottom sheet (14) in an open configuration for enhanced ventilation. A top pole (54) is also provided across the top sheet 12 near the head end (20). The top pole (54) cooperates with the flexible end pole (48) to form a sloped roof over a user's head and to hold the top and bottom sheets (12) and (14) in a selected degree of an open configuration. Optional mounting snaps (62) in the interior (24) of the enclosure (18) enable a user to reconfigure the opening (26) without leaving the interior (24) of the shelter (10). The shelter (10) thus provides enhanced ventilation while the sloped roof formed by the top pole (54) prevents the entry of precipitation into the enclosure (18). Optional mosquito netting (32) is zippered on the interior of the opening (26).
