Abstract: A carry bag is formed of a flexible plastics material and has an outer wall, an inner wall defining a receiving space and being sealed to the outer wall to form an inflatable volume between the walls. There is a valve in the outer wall, and an opening through which articles can be inserted/retrieved into/from the receiving volume. There is a strap at the bag opening having a pair of fasteners at each of its ends. The fasteners can be attached to one another to form a handle.
