A vehicle body hatchback (12) is disclosed as including a hatch (16) that is movable between open and closed positions and has a hatch opening (24) with a soft top convertible closure (26) movable between open and closed positions with respect to the hatch opening (24). The convertible closure (26) includes a frame (28) movable between raised and stored positions and also includes a soft top (30) that is moved between the closed and open positions thereof upon movement of the frame between the raised and stored positions. Frame (28) of the convertible closure (26) preferably includes a main bow (34) having opposite ends (36) pivotally mounted on the hatch and also includes an auxiliary bow (54) having opposite ends (56) pivotally mounted on the main bow.
