The user may use releasable fasteners affixed above fixed connection points along each opposite side of the front and rear panels to adjust the size of the sleeve openings. Releasable fasteners are provided below the fixed connection points to allow the user to open or close the side edges of the front and rear panels below the fixed connection points. A plurality of releasable fasteners is provided along the bottom edges of the front and rear panels to allow the user to selectively adjust the fit about the user's torso.
