The present invention relates to a flexible hose (1) with a multiple-layer wall which surrounds a lumen (2), with the following layer arrangement: an innermost layer (1.1) which delimits the lumen (2) of the hose (1), a second layer (1.2) which is arranged on the innermost layer (1.1), an outer layer (1.3) which is arranged on the second layer (1.2), which flexible hose (1) is characterized in that the second layer (1.2) adheres to the first layer (1.1) and to the third layer (1.3), and in that the difference of the material-related standardized water vapour permeability, measured according to DIN 53122-1:2001-08, climate D, between the first layer (1.1) and the third layer (1.3) or the third layer (1.3) and the first layer (1.1) is at least 150 (g x µm) / (m2 x d), wherein the standardized water vapour permeability is the product of the water vapour permeability according to DIN 53122-1 and the film thickness which is used during the measurement. |
