An inflatable device is specified which has at least two surfaces (1, 2) which are each in the form of at least one bulge (dome) (3, 4, 6, 7), the surfaces (1, 2) being connected to one another at the ends of their respective bulges (3, 6; 4, 7) and being separated from one another between the ends, in order to form interspaces (intermediate spaces) (9, 10) for a fluid passing through, the concave sides of the bulges being directed in the same direction. Fields of application include, in particular, parachutes, hang gliders, portable items of clothing for jumping from heights and propulsion sails for maritime or land vehicles. <IMAGE>
