A vehicle window assembly includes a cap that includes a rooftop section, which extends in a transverse direction of the vehicle, and a side wall that extends from the rooftop section generally in a normal direction. The side wall includes an opening. The window assembly also includes a rigid window that includes an interior surface and an exterior surface. Moreover, the window assembly includes a pivot coupling that pivotally connects the window to the cap for rotational movement between a closed position and an open position. The window covers the opening and the interior surface is operable to face the vehicle passenger compartment when the window is in the closed position. The window overlaps the rooftop section and the exterior surface faces the rooftop section when in the open position.
