Beschreibung
Zusammenfassung:	The present invention relates to a flexible hose (1) having a multilayer 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) arranged on the innermost layer (1.1), an exterior layer (1.3) arranged on the second layer (1.2), features of which are that the second layer (1.2) adheres on the first layer (1.1) and on the third layer (1.3) and that the difference in the material-related standardized water vapour transmission, measured in accordance with DIN 53122-1: 2001-08, climatic conditions 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 m) /(m2 x d), where the standardized water vapour transmission is the water vapour transmission in accordance with DIN 53122-1 multiplied by the foil thickness on which the measurement is made.
