Abstract: An improved jump suit with a rear drop-seat panel that opens downwardly is provided. The suit has a flexible panel mounted across the inside front portion thereof to define pockets therewith. The panel further extends on either side of the suit to define tapered flaps which overlap around the rear portion of the suit near the waist and under the drop-seat panel when it is raised to the closed position.The overlapped flaps are joined by attaching means such as VELCRO and the drop-seat panel has attaching means thereon such as VELCRO or zippers which engage matching fasteners on proximate portions of the flaps when the panel is closed over the flaps.The overlapped flaps supplement the strength of the jump suit and enhance the fit thereof and reduce draftiness at the seams of the drop-seat panel.
