A technical hose with foam insert, expediently a maritime swimming hose for drawing-off oil, as well as to the process for the production thereof. The hose according to the invention consists of the elastic cross-linked elastomer layer containing also fibre-reinforcement, of the foam layer with closed cells arranged above said layer and assuring swimming ability, as well as of the new type of outer coating sheet. The outer coating sheet is a multi-layer system, the elementary layers are previously partially cross-linked, in their cross-section inhomogenous elastomer layers, stretched longitudinally in a given case, being interconnected and connected to the foam layer, respectively, by means of thermally and/or chemically activated adhesive layers.
