Abstract: A water-proof fabric has a perimeter consisting essentially of a straight section and a remaining section. The perimeter of the remaining section is circumscribed by first and second zipper tapes arranged in series. The perimeter of the straight section is circumscribed by third and fourth and fifth zipper tapes in series. The fourth zipper tape is located centered around a center of the straight side. The second zipper tape extends along the remaining side to an end of the remaining side. The fifth zipper tape extends along the straight side to the end of the straight side in an orientation to mesh at the corner with the second zipper tape. The fourth zipper tape mates with itself to form a cape. When the first zipper tape mates with itself and the second zipper tape mates with the fifth zipper tape a bivy tent is formed.

Abstract: An outdoor shelter system has a bottom water-proof fabric with a perimeter and zippers circumscribing the perimeter. The bottom water-proof fabric can have a hood and be worn separately as garment. An upper fabric has zippers circumscribing its perimeter that mesh with zippers of the bottom water-proof fabric. The surface of the upper fabric accommodates at least one support pole, and is crossed by each support pole at a portion. Each of the zippers on the perimeter of the bottom water-proof fabric mate by zipping to corresponding ones of each of the zippers on the perimeter of the upper fabric to form the outdoor shelter system fully enclosed by a floor, walls and ceiling with the bottom water-proof fabric at the bottom serving as a floor and part of walls and the upper fabric on top, serving as the ceiling and part of the walls.
