Abstract: A first panel-like element has a longitudinal fold near a first longitudinal edge. A second panel-like element has a longitudinal crease near a second longitudinal edge. The first longitudinal edge and second longitudinal edge are parallel to each other and form a longitudinal opening. A fastener is disposed at said longitudinal opening. When the fastener of the closure is closed, the first element and a second element form a flat, longitudinal flap, and the longitudinal opening and the fastener are located on the inside surface of the flap.

Abstract: An adjustable hood system for simultaneously adjusting the shape of the hood on wearer's head in directions having longitudinal, lateral and vertical components with a single drawstring. Each side has a front passageway that extends from the temple area, along the face opening, and then curves backward. Each side also has a back passageway that extends backward from the top of the hood and then curves downward and then curves forward. The front passageway and the back passageway each have openings adjacent to each other in the lower region. On each side, one end of a drawstring is attached to the upper end of the front passageway, the other end is attached to the top end of the back passageway, and a portion of the drawstring is exposed between the openings in the lower region where it may be manipulated by the wearer for adjustment of the hood. Preferably, a cinch clamp is disposed on the exposed section of the drawstring to maintain an adjustment.
