    • A hose arrangement comprising an outer tube 11 of flexible material and an inner tube 12 of an elastic material for carrying fluid through the hose arrangement, wherein due to the action of the elastic inner tube, the hose arrangement has a shorter length in a contracted state in the absence of fluid pressure in the interior of the inner elastic tube and a longer length in an expanded state when fluid pressure is applied to the interior of the elastic inner tube, and the outer tube has an undulating state when the hose arrangement is in the contracted state and serves to control and contain expansion of the inner tube when the hose arrangement is in the expanded state. The flexible material of the outer tube comprises a woven fabric which is woven from two types of yarn, a first type of yarn 9a being of a first material and a second type of yarn 9b being of a second material, which is different from the first material.
