A hose having a low permeation rate, in particular a hose for a high temperature coolant, having at least the following layer configuration: a barrier layer in the form of monofilm or multilayer film made of a polymer material; an inner layer that is placed on top of the barrier layer and is made of a polymer material having elastic properties; a reinforcement supported by the inner layer made of threadlike material, and an outer layer made of a polymer material having elastic properties, which protects against external influences. The reinforcement features a spiraled shape, specifically by forming at least two spiraled layers, wherein the area between two spiraled layers is free of an intermediate layer of a polymer material. In addition, the area between two spiraled layers is in particular free of a bonding agent. Further a method for producing such a hose is disclosed.
