An inner bottom piece (14) connected to the two sides along a bottom seam by stitching (36). An outer bottom piece (16) comprising an outer layer (44) and an inner layer (46), the inner layer being impermeable to water and permeable to vapor. The outer bottom (16) extending outwardly beyong the bottom seam in overlapping relationship to portions of the sides adjacent the bottom seam, the outer bottom piece (16) adhered to the inner bottom piece (14) and overlapped portions of the sides to form a waterproof seal between the outer bottom piece (16) and the sides (12).
